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.

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.

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

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.
