Know All About Cataract Surgery For Diabetic Patients

Know All About Cataract Surgery for Diabetic Patients

Diabetes is a growing systemic disease, and many patients undergoing cataract surgery also have diabetic eye disease. Modern cataract surgery can restore excellent vision and correct myopia, hyperopia, and astigmatism in otherwise healthy eyes. However, if there is coexisting diabetic eye disease, cataract surgery may place additional strain on the eye, leading to macular edema, progressive retinopathy, and limited vision.

Although you can still achieve excellent results from cataract surgery in diabetic patients, these patients are at a higher risk of complications and subsequent vision loss. Diabetic patients can achieve near-perfect vision after cataract surgery with careful preoperative planning. And with attention to detail during phacoemulsification and close postoperative supervision.

Today, you will learn more about how diabetes affects your eyes and how cataract surgery works on diabetic patients. Here’s a detailed account of the subject and why you should consider all factors before opting for eye surgery. Moreover, comprehensive consultation with your doctor can change your understanding and give you a better perspective.

What Is Diabetic Cataract?

Diabetes is a significant contributor to the development of cataracts. Although the reasons for this are still unknown, according to some studies, people with diabetes mellitus have a 60% increased risk of developing cataracts. Maintaining proper control of your blood sugar levels, as with most diabetes complications, will help to reduce your risk.

Furthermore, research indicates that people with type 2 diabetes who significantly reduce their HbA1c level by just 1% minimize their risk of cataracts by 19%.

Cataract treatment has come a long way in recent years. Surgery is frequently recommended, with the lens being removed and replaced with an artificial one. Cataract surgery is widely recommended and performed regularly.

Why Do Diabetics Get Cataracts?

Diabetes affects your body in several ways. Therefore, it can have an impact on your eyes as well. Individuals with diabetes are not only more prone to developing cataracts, but they are also much more likely to develop them at a younger age and to progress more quickly than people without diabetes.

The aqueous humor, the fluid that fills the front of the eye, provides oxygen and glucose to the lens of your eye. If you do not control your glucose levels, such as a diabetic patient, the sugar levels can rise, causing the lens to swell. As a result, your glasses prescription may change. Furthermore, the lens contains an enzyme that converts glucose to sorbitol. Sorbitol accumulation in the lens can harm cells and other proteins, making the lens more opaque.

So, if you have diabetes, you should get your eyes checked at the earliest to avoid any uncalled-for surprises in the future.

Can Diabetes Affect Your Eyes?

The straight answer is yes! Diabetes or high blood sugar can harm your eyes, leading to several eye conditions like cataracts, glaucoma, blurry vision, or retinopathy. If you have diabetes at a younger age, it can give rise to problems in the future. The only way out for you is to have your eyes checked regularly. So can nip the issue in the bud as and when it arises.

Apart from cataracts, diabetes can cause other eye conditions, such as:

  • Glaucoma

Diabetic patients are more likely to develop glaucoma, which can manifest itself in a variety of ways. When fluid does not drain properly, pressure builds up inside your eye. It can cause nerve and blood vessel damage, as well as vision changes.

  • Blurry Vision

Don’t go out and buy new glasses the moment you notice that things are blurry. It could be a minor issue caused by high blood sugar. Your lens may swell, impairing your ability to see. To correct it, you must return your blood sugar to the normal range (70-130 milligrams per deciliter, or mg/dL, before meals, and lower than 180 mg/dL 1 to 2 hours after a meal).

  • Diabetic Retinopathy

Diabetic retinopathy gets caused by damage to the small blood vessels in your retina. It is associated with high blood sugar levels. You could go blind if you do not catch it and treat it right away. The longer you have diabetes, the more likely it is that you will develop it again. You can reduce your chances by keeping your blood sugar under control.

  • Cataracts

The natural internal lens of your eye, like a camera, allows you to see and focus on an image. When that lens becomes cloudy, as if it were a smudged window, a cataract has formed. They can happen to anyone, but people with diabetes are more likely to get them and have them worsen faster.

Therefore, if you do not want diabetes to impact your vision adversely, make sure you have your eyes checked regularly and lower your blood sugar levels to avoid any drastic consequences.

Can A Diabetic Patient Have Cataract Surgery?

Every cataract surgery patient has a preoperative evaluation, but diabetic patients can expect a more thorough assessment. There will be a greater emphasis on tests that assess the extent of diabetes-related eye changes. If a cataract patient reports visual problems affecting their quality of life, a doctor will run additional tests. It is to ensure that the cause of vision loss is cataract and not any other.

For instance, diabetic retinopathy affects some diabetic patients, which occurs when high blood sugar levels damage blood vessels in the retina. As a result, a retina specialist may get involved in the evaluation process before cataract surgery. A thorough eye exam may reveal other pathologies, in which case the doctor may consider a treatment plan before cataract surgery.

That said, a diabetic patient can have cataract surgery but with extra tests and evaluations to minimize risks during the process.

Is Cataract a Complication Of Diabetes?

Yes, diabetes can cause cataracts, and their removal may enhance your blurred vision. However, due to other complications, cataract removal may get slightly unmanageable. Essentially, you will find a two-fold impact of cataracts.

  • Due to the weak view of the retina, laser and intravitreal injections may become impossible. They treat diabetic visual complications such as diabetic retinopathy or maculopathy. Without treatment, these conditions can worsen to the point where potential vision is so poor that cataract removal will not improve vision.
  • Cataract-related vision loss complicates the timely administration of blood glucose-controlling medication (blood sugar). It is especially true for those who must use insulin injections.

Unfortunately, cataracts tend to develop early in diabetics and progress quickly if blood sugar control is poor. It is most likely due to osmotic changes occurring within the lens, typically resulting in cortical or posterior subcapsular lens opacities.

Is Cataract Surgery Safe For Diabetics?

When evaluating cataract patients who also have diabetes, doctors must consider several factors. The first of which is how well diabetes gets controlled. If your blood glucose levels are too high, your doctor may advise you to postpone surgery as it may not be safe to perform.

Cataracts develop at a younger age in diabetics, and it may be preferable in some cases to perform cataract surgery at an earlier stage in cataract development to reduce the risk of complications. Cataract surgery can cause diabetic retinopathy to progress, but in eyes with minimal diabetic changes, cataract surgery is less likely to cause this progression. As a result, you may get advised on surgery at an earlier stage.

Cataract surgery entails removing the eye’s natural lens and replacing it with an artificial lens, known as an intraocular lens or IOL. Doctors avoid certain types of IOLs in diabetic patients in some cases. Diabetic patients will be able to discuss IOL options with a qualified eye doctor.

What Is The Best Treatment For Diabetic Retinopathy?

Diabetic retinopathy may or may not threaten your vision. However, if it does, seeking an expert ophthalmologist’s help will do wonders in keeping your eyes in check. When it comes to treating diabetic retinopathy, if it affects your sight in any way, the following treatments will work in your favor (after consulting your eye doctor, of course):

  • Laser Treatment – It is used to treat the growth of new blood vessels at the back of the eye (retina). It is in cases of proliferative diabetic retinopathy and to stabilize some cases of maculopathy
  • Eye Injections – They are used to treat severe maculopathy threatening your eyesight
  • Eye Surgery – It helps remove blood or scar tissue from the eye if laser treatment does not yield proper results because retinopathy is too advanced

Following the procedure, you will most likely have blurred vision. It should gradually improve, though it may take several months for your eyesight to return to normal. During your recovery, your surgeon will advise you on any activities you should avoid.

Can Diabetics Do Cataract Eye Surgery?

Almost everyone eventually develops age-related cataracts. More than half of people over 65 years of age have a cataract, and the prevalence rises with each decade of life. Since diabetes has become more common, many diabetic patients seeking cataract surgery question if doctors can h3restore vision loss due to cataracts.

Although there may be an increased risk of complications and some limitations, diabetic patients can benefit from cataract surgery. The doctor will go over the evaluation process with you, discuss the factors to consider, and assist you in your recovery from surgery.

Can Type 1 Diabetics Get Cataract Eye Surgery?

The risks associated with cataract eye surgery for Type 1 diabetes patients remain plenty. However, with careful evaluation and procedural follow-up, you can get it done. Initial tests and assessments will give an insight into the condition of your eye and help your doctor create a treatment plan for you.

Depending on the extent to which your eye has been affected, your ophthalmologist will recommend the necessary treatment. If cataract removal through laser, injections, or surgery is possible, your eye doctor will proceed with the same.

Can Type 2 Diabetics Get Cataract Eye Surgery?

Since you can improve your blood sugar levels in case of Type 2 diabetes, some lifestyle changes or modifications will work in your favor. Especially in the case of cataract eye surgery, it can help. Sometimes, cloudy vision problems can get solved with cataract surgery, while at other times, your eye doctor may recommend a different treatment. However, if you have Type 2 diabetes, you can get cataract eye surgery if the doctor prescribes it.

Remember, high blood sugar can lead to several eye conditions, including cataracts. However, the treatment may not necessarily entail eye surgery. Therefore, it deems essential that you consult a certified and qualified ophthalmologist with years of experience in the field to assist you.

How Effective Is Laser Treatment For Diabetic Retinopathy?

In the advanced stages of diabetic retinopathy, laser treatment gets used to treat new blood vessels at the back of the eyes. It gets done because the new blood vessels are usually weak and frequently cause eye bleeding. Treatment can help stabilize the changes in your eyes caused by diabetes and prevent your vision from deteriorating, but it will not usually improve your vision.

Laser treatment involves shining a laser into your eyes, and you will be given local anesthetic drops to numb your eyes. Doctors use eye drops to widen your pupils and special contact lenses to hold your eyelids open and focus the laser onto your retina. The process isn’t usually painful. However, you may feel a prickly sensation when specific areas of your eye get treated.

The entire procedure takes around 20-40 minutes usually and gets carried out on an outpatient basis. In the coming days, you may require to visit your eye doctor more than once to make sure the procedure went well.

Factors To Consider For Diabetic Patients Contemplating Cataract Surgery

When evaluating cataract patients with diabetes, your ophthalmologist will have many factors to consider, such as:

  • Diabetes control
  • Delaying surgery in case of high blood glucose levels
  • Performing cataract surgery early to reduce risks of complications

Cataract surgery involves the removal of the natural lens of your eyes. It gets replaced with an artificial lens – intraocular lens or IOL. In specific cases, the eye doctor may have to avoid some types of IOLs in patients who have diabetes. You can discuss your IOL options, if you have diabetes, with a qualified eye doctor.

Cataract Surgery Recovery For Diabetic Patients

Diabetic patients who have cataract surgery may require more supervision and evaluation afterward. To prevent and treat fluid buildup (macular edema) and swelling or inflammation, you may get prescribed topical steroids and anti-inflammatory drugs. Diabetes patients are more likely to develop a condition known as posterior capsule opacification, also known as a “secondary cataract.” Although not a cataract, this condition can give you an impression that the cataract has returned; however, it is usually treatable with a routine outpatient laser procedure.

Even though having diabetes presents unique challenges and may result in a more prolonged recovery time, thorough pre-and post-treatment can lead to good cataract surgery results.


Diabetes can lead to several challenges, and cataract surgery may just become one of them. However, if you follow a proper preoperative and postoperative course, you can deal with these tests with gumption. While the difficulties may seem plenty, a significant part of your surgery and recovery will only get based on your ophthalmologist’s diagnosis and treatment.

Moreover, consider your daily actions and how they might affect your recovery. In the first few days after your cataract surgery, your eye needs extra care and precautions, and eventually, the rest will fall into place.

Remember only to reach out to the most advanced eye-care hospitals and clinics for your cataract surgery if you have diabetes or even otherwise.

The procedure is usually done as an outpatient and does not necessitate an overnight stay in a hospital or other care facility. The majority of modern cataract procedures involve using a high-frequency ultrasound device to break up the cloudy lens into small pieces, which are then gently suctioned out of the eye.

This procedure is conducted with tiny incisions than past surgical techniques for cataract removal, resulting in faster healing and a lower risk of cataract surgery complications such as retinal detachment.

Experienced surgeons are well-versed in the most recent technologies and have had ample hands-on experience with modern tools. Consult an ophthalmologist with at least 20 years of experience.

  • Reputation

Some eye patients may believe that a doctor’s reputation is unimportant. But it is essential when it comes to treatment. Check a doctor’s qualifications, registrations, and success rate before scheduling an appointment. If you’re having trouble getting around, go online and look at a few websites. You will learn everything there is to know about an eye surgeon. Also, if possible, look up an eye doctor’s online ratings and reviews. So you don’t end up with a specialist with a tarnished reputation.

  • Technology Used
  • Using cutting-edge technology to promote safety and accuracy in various eye surgeries, including cataract surgery, is essential these days. Consult your friends if they are sure about a particular eye specialist who performs surgery using updated and advanced medical technology. If you are unsure whether an eye specialist has all of the necessary tools, you can find out by visiting their website for more information.

  • Cataract Surgery Cost in India

Cost is an important consideration when making any decision. But you should know not to cut corners in your cataract treatment. The cost varies depending on the ophthalmologist you consult and the location. Remember that your safety and the accuracy of the procedure are the most important considerations. An expert eye surgeon, skills, technology, and modern equipment should not cost you an extravagant amount.

  • Patient Benefits

You can be confident that you will never have cloudy vision again if you have cataract surgery. Although cataract treatment changes with each advancement in technology, the procedure remains the same even today. However, now that you have new lenses to choose from, doctors have an extensive range of options that may work well for a specific patient. Whether you pick out the lens or rely on your ophthalmologist, choose one that works very well for you.

  • Friendly or Family Recommendations

If you get recommendations from friends and family members, they are always welcome. Many people are aware of cataract treatment because it is an essential eye treatment. You can inquire about a specific doctor, their experience, whether they use cutting-edge technology, whether their clinic is easily accessible and much more. If you find their responses convincing enough, take the plunge.

  • Financing Options

Many eye clinics offer to finance. You can check online to see if a specific eye clinic has this provision or not. You can also inquire with your insurance company to see if they will cover the entire cost of your cataract treatment. If that is not the case, you can consider opening a Flexible Spending Account (FSA). The funds in your FSA can be withdrawn tax-free and used for such purposes – as cataract treatment.

  • Location Advantages

Check to see if the clinic for your cataract surgery is close by and not too far off. If the hospital is far away, it can get hard. You will need to bring a friend or family member with you during the procedure. So, for your convenience, choose eye clinics or hospitals that are close to your home. Furthermore, the price may differ from one city to the next. As a result, location is also an essential factor in the cost calculation.

  • Testimonials from Previous/Current Patients

Testimonials from previous or current patients for the eye surgeon can help you decide whether they’re the right fit for you. Testimonials ensure that an ophthalmologist is effective in treating their patients. You can find these testimonials on their website, social media platforms, or other channels. Don’t forget to check each of them, and once you’re confident that the testimonials are genuine, you can schedule an appointment with the eye doctor.

  • Surgeon Commitment

If you want the procedure to go smoothly, the surgeon’s commitment is required. Check to see if the appointed ophthalmologist has any government or non-governmental organization accreditation or awards. In this case, your friends, family members, and the internet can be very beneficial. You can visit their website and read through each page to determine whether or not the surgeon understands the extent of their work and is committed to surgery.

  • Average Recovery Time

Many people report that they have clear vision within a few hours of having cataract surgery. However, everyone heals differently, so it could be a week or two until you see images in their sharpest focus. The day after the procedure, your scheduled follow-up consultation with your cataract surgeon will help you understand your progress. It ensures that no complications arise.

  • Infrastructure

During the procedure, infrastructure plays an important role. You can check if a particular eye clinic has all of the necessary amenities and equipment and that their staff members are friendly and candid. You can also find out if the eye clinic has a dark room for post-surgery patients. If an eye clinic meets all of the above requirements, you can go ahead with your cataract surgery here.

  • Comprehensive Eye Care

You should ideally seek an eye surgeon who has vast knowledge and experience in ophthalmology. They should not remain skilled in a single type of surgery but also cataracts and other eye surgeries. It ensures that a doctor is well-versed in all surgical procedures and has extensive experience in ophthalmology.


Your ultimate goal is to get the correct treatment for your eyes. Selecting the best hospital offers you the conviction to go for cataract surgery and emerge successfully.

Dos & Donts After Cataract Surgery - A Complete Post-Operative Care Guide

Do’s & Don’ts After Cataract Surgery: A Complete Post-Operative Care Guide

A conventional age-related condition, in cataracts, the natural lens of the eye becomes cloudy and less transparent. While it may initially have little impact on your sight, cataracts can grow over time, and it may start to interfere with your abilities to accomplish everyday tasks if it remains unaddressed. It is usual for the level and quality of vision achieved to decrease as a result of a cataract.

Cataract surgery usually takes lesser time to complete. The surgery takes less than an hour. The doctor will first place eye drops in your eyes to dilate the pupil. Local anesthetics will get administered to numb the area. The doctor may even apply a sedative to assist you in relaxing. If given a sedative, you will be awake but groggy throughout the procedure.

Today, you will learn more about the aftercare procedure once your cataract surgery gets complete.

What is a Cataract Surgery?

Cataract surgery typically takes no more than 15 minutes and is performed under local anesthesia, making it virtually painless. While the procedure itself is very prompt, it can take a while for your eyes to acclimate to the synthetic lens used to substitute your natural lens in the days or even weeks post-surgery.

There are several things you can do while recovering from surgery. You need to care for your eyes and optimize the overall healing process. To assist you in preparing for this, we have created a comprehensive guide. It covers everything you could want to know about the dos and don’ts following cataract surgery.

Tips for Post-Cataract Surgery

You should be able to leave the hospital the same day as your cataract surgery. When you leave the hospital, you may have a pad and plastic shield over your treated eye, which can usually get removed the next day. The feeling should return to your eye after a few hours after surgery, but vision may take a couple of days to recover.

These side effects usually go away after a few days, but it can take 4 to 6 weeks to fully recover. If you require new glasses, you will be unable to order them until your eye has completely healed, which usually takes six weeks. Cataract surgery has a high success rate in improving your vision and should allow you to resume normal activities such as driving.

However, keep the following tips in mind to ensure a good recovery.


  • Avoid activities that are strenuous on your eyes in the early post-op phase.

Avoiding activities, which are taxing on your eyes is critical to promoting healing, so take it easy in the first week after treatment. Throughout your various aftercare appointments, your ophthalmologist and clinical care team will be able to make the best recommendations for you.

  • Use eye drops as instructed by your eye surgeon.

Your eye surgeon will prescribe antibiotics as well as anti-inflammatory eye drops after surgery. You must use these drops as directed. They are critical in preventing infection and inflammation and thus aiding the healing process.

  • Show up for every aftercare appointment.

Receiving systematic aftercare is critical to ensuring that your recovery progresses as intended, so you must attend all of your routine follow-up appointments as instructed by your ophthalmologist and surgeon.

  • Take painkillers if needed (and prescribed).

Although the treatment itself is painless, some individuals may suffer minor discomfort during the early healing process. It usually goes away as your recovery progresses, and you can use over-the-counter pain relievers like paracetamol to alleviate any discomfort and make the healing process more comfortable.

  • Use your protective eye glasses or eyewear.

Following surgery, it is critical to use protective glasses in the early stages to reduce the risk of infection and, as a result, to guarantee a proper healing process. Wearing goggles or shields at night will keep you from rubbing your eyes while sleeping, and wearing them in the shower will keep water, soap, and shampoo out of your eyes.

  • Rub your eyes.

For a variety of reasons, vigorous rubbing of your eyes can hurt the healing process. Rubbing, for example, can result in bacteria entering the eye, which can lead to infections. Furthermore, putting pressure on your eyes through extensive rubbing can harm the cornea, the outer window of the eyes and is detrimental to the healing process.

  • Drive after surgery.

You should avoid all intensive activity directly afterward your treatment, which means you would be unable to drive the day of surgery. We recommend that you arrange transportation home ahead of time, preferably by a friend or family member who will be able to see you inside and ensure that you are comfortable once you arrive.

  • Wear eye makeup for the first week post-surgery.

One of the few precautions you should take after surgery to aid the healing process is to avoid wearing eye make-up. Even when you’re extra cautious, make-up particles can irritate and lead to infection during the recovery period, so you are recommended not to wear any for at least the first week after treatment.

  • Swim or use sauna.

Swimming pools, hot tubs, and saunas should be avoided in the first few weeks after treatment because water can carry bacteria that are harmful to the eyes. Swimming gets considered a strenuous activity, and you ought to evade it in the days following treatment.

  • Expose your eyes to dust or dirt.

Because your eyes will be more sensitive during the healing process, it is critical to avoid all possible allergens to achieve a smooth recovery. Airborne irritants such as dust and pollen, as well as dirt, smoke, wind, and sunlight, can all be considered.

What Is a Typical Cataract Surgery Recovery Time?

Don’t get too concerned if your vision appears cloudy, blurry, or distorted after you remove the eye shield for the first time. It may take time for your visual system to adjust to the cataract removal and the intraocular lens used to replace your natural lens. During this initial adjustment, some patients even report noticing “wavy” vision or distortions. This phenomenon, if it exists, should last for a short time.

Many people experience having clear vision within a few hours of getting cataract surgery. However, everyone heals differently, and it may take up to a week or two before you see images in their sharpest focus. A follow-up consultation with your cataract surgeon gets scheduled the day after the procedure. It ensures that there are no complications.

If you don’t start noticing any improvement in your blurry vision, or if you experience eye pain or considerable distress in the days following this visit, please notify your surgeon.

Follow every one of these dos and don’ts after your cataract surgery to ensure a good recovery. If you need both eyes treated, the sooner your first eye heals, the sooner you can get treatment for your other eye.

While the list may appear detailed, a significant part of your recovery will only get based on reason. Consider your daily actions and whether they might affect your recovery. In the first few days after cataract surgery, your eye is essentially an open, healing wound. Take extra precautions in the first few days, and the rest will fall into place.

Remember only to reach out to the most advanced eye-care hospitals and clinics for your cataract surgery. The experts at Dada Laser Eye Institute will guide you through the entire process.

Cataract Types, Causes, Symptoms & Risk Factors

Cataract Types, Causes, Symptoms and Risk Factors

Clear vision remains one of the essential attributes to function well in your day-to-day life. When it gets compromised, it can cause trouble in performing basic tasks. We have a natural lens inside our eyes. The lens bends (refracts) light rays that enter the eye to assist us in seeing, and it should be clear. Your lens becomes cloudy if you have a cataract. It’s similar to looking through a foggy or dusty car windshield. With a cataract, things appear blurry, hazy, or less colorful.

Cataracts are most common in people over the age of 55. However, as a result of trauma or medications, they can also occur in infants and young children. Cataracts usually develop in both eyes, but one may be worse than the other. Cataract treatment gets determined by the degree of visual impairment caused by the cataract. If a cataract only has a minor impact on vision, or if it has no impact at all, you may need no treatment. It is advisable to keep an eye out for any increased visual symptoms and maintain a regular check-up schedule.

Today, you will learn more about cataracts – their causes, types, symptoms, and risk factors. It will give you an insight into the eye condition.

What is Cataract?

A cataract is a clouding of your eye’s usually clear lens. Seeing through cloudy lenses is similar to looking through a frosty or fogged-up window for people who have cataracts. Cataracts can cause clouded vision, making it difficult to read or drive a car (especially at night). Most cataracts develop slowly and do not interfere with your vision at first. However, cataracts will eventually obstruct your vision.

Intense lighting and eyeglasses can help you deal with cataracts at first. However, if your vision keeps interfering with your daily activities, you may require cataract surgery. Changes in the proteins and fibers of the lens cause the clouding of the lens. Cataract surgery, fortunately, is generally a safe and effective procedure.

What are the Cataract Types?

Cataracts form when protein deposits in the lens of your eye, causing it to become cloudy. It prevents light from passing through. You may lose some of your vision as a result of it.

Many layers make up your eye lens, much like an onion. The capsule is at the very top. The cortex is the layer inside this capsule, and the nucleus is the layer on the inside. A cataract can form in any of these locations. Cataracts get their name from where they are in the lens and come in a variety of forms.

Here is the list of various Cataract Types due to their causes and severity:

  • Nuclear Cataracts

Nuclear cataracts, also known as nuclear-sclerotic cataracts, are the most common type seen by doctors. Someone who lives long enough usually acquires one. They form in the nucleus of the lens, located in the center of the lens. As they deteriorate, your reading vision may improve. It’s called second sight, but it’s fleeting.

  • Cortical Cataracts

Cortical cataracts take shape on the cortex, located on the outside edge of your lens. They begin as white wedges that resemble triangles and point toward the center of your eye. They scatter light as they grow. The most noticeable symptom is glare. Driving at night may be difficult for you.

They can also cause your vision to become hazy as if you’re looking through a fog. It may get hard to distinguish between similar colors or to determine how far away an object is. Because they can cause problems with both near and far vision, they usually get removed early on.

  • Congenital Cataracts

Congenital cataracts you are born with or develop as a child. Some get caused by your genes, while others get caused by an illness. They may not require treatment if they are small or outside the center of the lens. However, if a baby is born with one that blocks vision, a doctor must remove it because it can prevent the eye from learning to see.

  • Posterior Subcapsular Cataracts

Posterior subcapsular cataracts develop just inside the back of your lens capsule, which is the part of your eye that surrounds and holds the lens in place. They are directly in the light’s path as it passes through the lens. They manifest faster than other types of cataracts, and you may notice symptoms within months. They impair close-up vision and make it difficult to see in bright light.

  • Anterior Subcapsular Cataracts

Anterior subcapsular cataracts develop near the front of your lens capsule. It can get caused by an injury or swelling in your eye. Atopic dermatitis, a type of eczema, can also cause this.

  • Secondary Cataracts

When a cataract develops due to another condition or medical treatment, it gets referred to as secondary cataract formation. Diabetes, the use of steroids such as prednisone, and even cataract surgery are all potential causes.

You will find many other cataract types, but these get priority due to their causes and severity. In any case, if you have blurred vision, you need to get your eyes checked by a certified and experienced ophthalmologist at the earliest.

What Are the Causes of Cataract?

The most common cause of cataracts remains aging. It is due to usual eye changes that begin around the age of 40. That is when normal proteins in the lens begin to degrade. It is what makes the lens cloudy. People over the age of 60 usually experience some clouding of their lenses. However, vision problems may not appear for years.

Some inherited genetic disorders that cause other health problems can increase your chances of developing cataracts. Other eye conditions, previous eye surgery, or medical conditions such as diabetes can also cause cataracts. Long-term use of steroid medications can also result in the development of cataracts.

Let’s take a look at some of the causes of cataracts, other than aging.

  • Diabetes: People with diabetes are more likely to develop cataracts.
  • Medications: Certain medications have become linked to the development of cataracts.
  • Ultraviolet Radiation: According to research, unprotected exposure to ultraviolet (UV) radiation has seen linkage to an increased risk of cataract formation.
  • Smoking: There may be a link between smoking and increased lens cloudiness.
  • Alcohol Consumption: Several studies have found that patients who consume more alcohol have more cataracts than those who consume less or no alcohol.
  • Nutritional Deficiency: Although the findings are inconclusive, studies suggest a link between cataract formation and low antioxidant levels (for example, vitamin C, vitamin E, and carotenoids). Further research may reveal that antioxidants can aid in the reduction of cataract growth.
  • Family History: If a close relative has had cataracts, you are more likely to develop one yourself.

Cataracts are rarely present at birth or develop soon after. You can inherit them or acquire them due to maternal infection (such as rubella) during pregnancy. A cataract can also develop due to an eye injury or surgery for another eye condition, such as glaucoma.

What are the Symptoms of Cataract?

Cataracts usually form slowly. You may be unaware of their presence until they begin to block light. Then you may notice:

  • Blurred or hazy vision.
  • Colors have a lower intensity.
  • Increased sensitivity to light glare when driving at night.
  • Night vision becomes harder.
  • Change in the refractive error of the eye, also known as an eyeglass prescription.
  • Color fading or yellowing.
  • In a single eye, you have double vision.

At first, the cloudiness in your eyesight triggered by a cataract may impair only a tiny fraction of the eye’s lens, and you’d be oblivious of any vision loss. As the cataract grows in size, it clouds more of your lens and distorts the light that passes through it. It could result in more noticeable symptoms.

  • Increasing age – The older you grow, the risk of cataracts amplifies.
  • Diabetes – A condition that can cause secondary cataracts.
  • Excessive exposure to sunlight – It results in excessive exposure to radiation, resulting in the need for cataract surgery.
  • Smoking – Some studies suggest smoking can hamper your vision, and when combined with other factors, can result in a cataract.

There is no treatment to prevent or slow the progression of cataracts. Changes in vision caused by age-related cataracts can be very gradual. Some people may fail to notice the visual changes at first. However, as cataracts progress, vision symptoms worsen. Researchers have linked eye-friendly nutrients like lutein and zeaxanthin, vitamin C, vitamin E, and zinc to a lower risk of certain eye diseases like cataracts. However, do not self-diagnose your eye condition. Seek help from a licensed and experienced ophthalmologist.

How to Select Lenses for Cataract Surgery in India?

What is a Lens?

As a commoner, when you hear about lenses, you think of those used as an alternative to eyeglasses. But, when it comes to eye lenses, their design is such that it both accepts and bends light. These particles of light then get pushed to the back of your eyes, where the brain converts them into images. However, when factors like age and underlying health issues come to the fore, your eye lens can get cloudy and blurred. Thus, calling for the need for corrective eyewear or surgery.

When it comes to cataract surgery, the ophthalmologist places another lens inside your eyes to sharpen the particles of light as they pass through. You will find most eye doctors using silicone or acrylic lenses for cataracts. They get coated with protective material to shield your eyes from the damage caused by harmful sun rays.

Today, you will learn more about the different lenses and the ones best suited for cataracts.

Best Lens for Your Cataract Surgery

How can you decide the best lens for you? Firstly, an expert opinion on the subject matters as it concerns your eyes and your vision. Secondly, with multiple options available, you can choose a lens that’s best-suited for your eyes. While your eye doctor may suggest the right kind of lens for you, the decision remains personal, and what you need from the eye surgery matters in this case.

You will come across four types of lenses used in cataract – monofocal, multifocal, accommodative, toric – designed to make your eyesight sharper and less blurred. Here, you can take a comprehensive look at all of them.

  1. Monofocal Lens – It is the most common lens used in cataracts. The primary purpose of the monofocal lens is to give you crisper, clearer vision at a predetermined distance range. Therefore, if you need to look closer or farther away from this set distance, you might need your eyeglasses.

In some cases, people who have opted for monofocal lenses can read, knit, or work on a computer without the help of glasses. However, when they need to watch things at a distance, they need to wear their glasses.

  1. Multifocal Lens – In your life, you will find some people who willingly wear glasses if the need arises. However, you will also find people opposed to the idea of depending on any corrective eyewear to help them see clearly. In the latter, the multifocal lens proves beneficial and has appeal too.

A multifocal lens has zones of focus. When your eyes get familiar with these lenses, the brain learns to select the clear-cut vision automatically. However, this lens has its challenges, and you need to consult your doctor to know if this is the right kind of lens for you.

  1. Accommodative Lens – If you’re uncomfortable wearing glasses or with the idea of using multifocal lenses, this is the perfect option for you. It moves or shifts in shape similar to your natural lenses and allows you to see things clearly, whether they’re near or far away.

However, some researchers suggest that eye exercises enhance the workability of accommodative lenses. So, before you opt for them, check with your doctor if you’re eligible.

  1. Toric Lens – In the case of astigmatism, these lenses will work wonders for you. Not unlike an accommodative lens, the toric lens changes shape. But, its design is such that it corrects your specific refractive error.

Some researches and studies suggested that a maximum percentage of people with toric lenses did not feel the need to wear glasses to see clearly at a distance, while others did not need reading glasses.


While the way cataracts get treated nowadays change with every innovation, the procedure remains the same. However, with new lenses to choose from, it gives the eye specialist a range of options that could work well for a particular patient. Whether you pick the lens or trust your ophthalmologist, select one that works well for you.
