Laser Cataract Surgery vs Traditional Eye Surgery

Laser Cataract vs Traditional: Which is Better

A cataract is a type of eye disease which makes your vision blurry and it happens generally due to age, tissue damage or genetic disorder. If anyone has a cataract, it means in their eye(s) a cloud-like substance has formed (in the focusing Lens) and is making the vision hindered. A cataract is the most common reason for vision loss in people who are 40+ and is also the primary cause of blindness in the world!

Cataracts Surgery Techniques

There are two main surgical methods for cataract and one of them uses laser, which has precision and no use of blades! Laser eye surgery is also considered the best for patients who have severe eye conditions such as astigmatism. And the other techniques for cataract surgeries are the traditional surgeries like Phaco and manual small incision (SICS).

Which Treatment is the Best for You?

Without any doubt, laser surgery is the best for you. Just like we mentioned, laser surgery is very accurate and there is no involvement of pain. With laser eye surgery, you can resume your work quickly as well. If you go for traditional surgery, you will have to undergo through the discomfort because traditional cataract surgeries include utilizing a vibrating needle to tear up cataracts, or the cloudy lens. They also use a blade to manually make a small incision inside the cornea via which the cloud-like substances are removed and the replacement lenses are inserted in their place.

How is laser-assisted cataract surgery done?

As the name suggests, the laser-assisted Semi-Robotic surgery involves the use of laser where a surgeon develops a deeper understanding of your eyes and the most specific of all problems. With laser cataract surgery, the incisions are made with the help of laser, which is also used to generate a better and more precise opening into the lens capsule. Moreover, laser energy is used to unstiffen the cataract before removal. After the laser steps, the cataract fragments are removed with the help of the same probe which is used in the traditional surgery and, in both the procedures, an intraocular lens is inserted.

Biggest Difference Between Traditional and Laser Cataract Surgery

The biggest difference between the two surgical methods is precision and the involvement of blades. Let’s understand this in a simpler way when a surgeon or an ophthalmologist performs laser-assisted surgery the chances of human errors are next to zero because most of the procedure is computer-assisted and the precision level is pretty high. There is discomfort at all because a surgeon won’t have to use a blade or any other cold-steel surgical instruments.

Now, let’s talk about- traditional surgery! The traditional surgery for cataract removal involves the use of blade and other surgical instruments. There is no use of Semi-Robotic technology here and the chances of errors are higher than usual. It is recommended to always go for laser-assisted eye surgery for your own good.

Last, but not least, laser-assisted surgery takes only few seconds to minutes per eye and when you compare it to traditional surgery it is was lesser! Also, after laser eye surgery, a patient can resume their work quickly and it involves zero post-medication care. Also, the laser-assisted surgery has a shorter recovery time (due to high precision and no use of blades) as compared to traditional surgery.

Benefits of laser cataract surgery which is absent in traditional cataract surgery

  • Semi-Robotic Computer based online assessment of eye during surgery
  • A laser cataract surgery increases accuracy and precision
  • A laser cataract surgery helps to reduce surgical time
  • Laser cataract surgeries do not require blades for cataract removal
  • Laser cataract surgery offers lesser recovery time

So, with the help of aforementioned references and points, it is not hard to understand now that the laser surgery is far better than the traditional one because the laser-assisted surgery is more accurate, takes lesser operating time, doesn’t need blades for making incisions, yields quicker recovery, and needs minimal post-operation care. Also, a patient can resume their work soon and start enjoying their life back without any possible issues.

Benefits of Laser Cataract Surgery

Many people are suffering from eye diseases like cataract and they are constantly looking for best ways to get rid of it. Very few people opt for traditional cataract surgery which is not that great because it lacks precision. On the other hand, majority people choose laser cataract surgery which uses a computer-assisted laser and renders a highly accurate procedure to free your eyes from cataract and it has helped myriads of eye patients to reclaim their vision back.

What is Laser Cataract Surgery?

Laser cataract surgery is also known as Refractive Laser-Assisted Cataract Surgery (ReLACS). It is a modern surgical treatment for cataract that uses FemtoSecond laser technology which brings a whole new level of accuracy in the procedure as compared to the old times when the cataract was being treated with the help of hand-held equipment. Laser cataract surgery has mainly 3 steps and those are-

  • The corneal incision
  • The anterior capsulotomy
  • Lens and cataract fragmentation

Now, let us see what role the aforementioned steps play during the process of laser cataract surgery

Corneal Incision: During regular cataract surgery, the surgeon utilizes hand-held medical equipment which has a diamond or metal blade and is used to make an incision in the exact area where the sclera meets the cornea. This incision permits the surgeon to enter the interior parts of the eye to crack up and remove the cataract.

A cataract clouds the eye lens and makes your vision blurry and generally happens behind the pupil. After that, the surgeon inserts an intraocular lens (IOL) to replace the cloudy lens which is causing blurry vision.

Anterior Capsulotomy: For your information, the natural eye lens is enclosed by a clear and very thin capsule. During laser cataract surgery the anterior part of the capsule is detached into a step known as capsulotomy. This procedure enables the surgeon to garner direct access to the lens which is affected by cataract.

It is of pivotal importance that the remaining part of the lens capsule which was intact in the eye must not be damaged during the surgery because it should hold the implanted lens for the rest of the life. Various studies and researches have shown that the capsulotomies performed with the help of a laser have more reproducibility and accuracy.

Lens and cataract fragmentation: Once the capsulotomy has been performed, the surgeon can access the cataract to remove it. In traditional cataract surgery, during the phacoemulsification process, there is a high chance that the ultrasound energy can build up heat and damage the incision and can negatively affect the outcome by inducing astigmatism.

But when we are dealing with laser cataract surgery, there are no chances of error. The laser softens the cataract as it tears up. By breaking the cataract into much softer and smaller pieces, a lesser amount of energy would be required to remove the cataract which in turn, boosts the overall accuracy of the entire process.

Should You Consider Laser Cataract Surgery?

Laser cataract surgery is a safe method for the treatment of cataract and has several other advantages, but this type of surgery is not for everyone. Why? It is because the user of a laser and the utilization of premium lenses are not covered by most of the insurance agencies and a patient will have to burn a hole in their pocket for the treatment.

So, if money is not your concern and you want the best possible treatment for your cataract then you must go for laser cataract surgery. It is safer and has lesser post-surgery care and maintenance.

Benefits of laser cataract surgery

Laser cataract surgery has myriads of advantages over traditional cataract surgery. Firstly, it is safer and requires lesser post-surgery care and maintenance. Apart from this, a patient has a better vision once the laser surgery has been performed. The accuracy of the laser assists a surgeon in giving people clearer vision faster, more consistently, and very often without glasses. The laser’s accuracy matters a lot when a surgeon wants to graft a multifocal lens which resolves close-up and distant vision or Toric lenses that has the capability to correct astigmatism.

Now, let us see the benefits of laser cataract surgery

Laser cataract surgery demands lesser energy: Researches say that the laser treatment requires 45% lesser ultrasound energy for achieving successful cataract removal and, during the procedure, the eye surgeons have to perform 45% fewer movements when compared with the traditional surgery. The laser pretreatment adds about five to seven minutes to the usual 10- to 15-minute cataract surgery.

Lesser cell damage: A survey tells us that no endothelial cells are damaged during the laser cataract surgery. This is really good because endothelial cells are the barometer of the eye-health as they preserve cornea’s clarity and are non-regenerative in nature. Another survey shows that during the standard treatment there is a huge loss of endothelial cells and it might range from 1 to 7%

Precision mapping: Before the surgical procedure starts, the laser cataract system allows a surgeon to create a 3D map of your eyes which helps in achieving exceptionally precise measurements for every step during the surgery.

Mild approach: The laser system is utilized to soften the cataract in the eyes, and it helps to break them into minute pieces which allow the scope for an easier and gentle way to remove the cataract. In traditional surgery, a surgeon used a hand-held surgical tool which has a metal or diamond blade.

Laser accuracy: During the first step of cataract surgery, a miniature opening is made with the help of a laser that holds the cataract together. For better accuracy, the laser makes the opening as circular as possible so that the new lens can be inserted without any hassle. For your information, the laser can be utilized to create impeccable incisions which can be used to correct astigmatism.

Now, we hope that you know what a laser cataract surgery is and what are its benefits for you. Laser cataract surgeries are safer and can be used to correct astigmatism as well. If you are having cataract then it will be a good option to visit an eye surgeon and get yourself treated as soon as possible.

Benefits and Advantages of ReLEx SMILE Surgery - DLEI

Benefits and Advantages of ReLEx SMILE Surgery

ReLEx SMILE surgery is one of the most widely performed surgeries in the world and is used to treat myopia and astigmatism. SMILE stands for Small incision lenticule extraction and earlier, it was known as Femtosecond lenticule extraction (FLEx). The entire method was developed by Carl Zeiss Meditec. ReLEx SMILE surgery has myriads of benefits when compared to traditional eye surgery and involves lesser precautions and is more accurate.

What is ReLEx SMILE Surgery?

The surgery is performed by an eye specialist or an ophthalmologist. ReLEx SMILE surgery is an advanced type of minimally invasive surgery which is bladeless, painless, and stitchless. It is a great alternative to eye traditional surgery methods such as LASEK and LASIK treatment.

In ReLEx SMILE surgery, a top-notch Carl Zeiss VisuMax laser is used which places a series of pulses in the center of the cornea which is affected. The accuracy level is very high in this type of surgery because it utilizes 3D mapping. These pulses form minute bubbles that have a 1/100th width of human hair and are used to outline the tissues that need to be removed because of deterioration. After this, the laser creates a minute tunnel which is used to draw out the damaged tissue.

This treatment demands no flaps and the whole procedure requires only few seconds for completion. The best part of this procedure is that 80% vision is restored within minutes. And after a few days, the patient’s vision will be magnificent and reaches normal level within a few days of time.

Benefits of ReLEx Smile surgery

Because laser is involved in this treatment, ReLEx SMILE is great in terms of accuracy. In this method, there is no chance of the flap moving, shifting, dislocating or folding and the chances of having dry eyes is negligible. Also, the procedure is considered to be a better alternative for the long-term stability of the cornea. The entire process takes place in a closed room and there is no chance for the involvement of external factors like – temperature, draft, dust or humidity.

  1. Flapless Method: ReLEx SMILE surgery has changed the way of refractive surgery is performed. Earlier, an eye specialist has to make a side-cut of approximately 28 mm. But now, a small incision which is lesser than 2 mm is sufficient enough to perform ReLEx SMILE which makes it a micro-incision keyhole procedure.
  2. 100% Femto: ReLEx SMILE surgery is a hi-tech method which utilizes Femtosecond laser for maximum accuracy. In this method of treatment, high-precision ZEISS VisuMax laser is used.
  3. Single-step procedure: ReLEx SMILE brings a lot of factors together which make the process easier to perform and more successful – the complete laser treatment and lenticule access and creation both take place in a single step.
  4. Indication range: ReLEx for myopia and astigmatism

Sphere: -0.50 to -10.00 D

Cylinder: 0 to 5.00 D

Spherical equivalent: -0.75 to -10.00 D

Comparison of ReLEx SMILE and LASIK Surgery

LASIK stands for laser in-situ keratomileusis. This is highly popular surgery and LASIK is used to treat vision problems in people who are suffering from farsightedness, nearsightedness or astigmatism. The procedure works by reshaping the cornea which is present in the front side of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye.

  • In a survey of 1000 patients, 82% of patients said SMILE is better, faster, and safer than LASIK treatment.
  • LASIK is a method where there is a need to create a FLAP and on the other hand, ReLEx SMILE is entirely a flapless procedure.
  • In ReLEx SMILE, an eye specialist uses only one laser during the procedure and that’s – Zeiss Femtosecond laser. In LASIK treatment, an ophthalmologist uses different brands of excimer lasers to treat eye problems.
  • Recovery time of the SMILE procedure is quicker than LASIK treatment.
  • Research suggests there may be less risk of dry eyes after SMILE, compared with after LASIK.

When it comes to overall advantage, ReLEx SMILE wins over LASIK over a big margin. The entire process is bladeless, flapless, painless, and stitchless. Also, the procedure is highly advanced which uses only Femtosecond laser for better accuracy. The patient does not suffer from dry eyes after the treatment in ReLEx SMILE.
