LASIK AND PRK
LASIK is a time-tested surgical procedure to remove glasses painlessly and effectively. The actual procedure takes only a few minutes, is pain-free, and provides clear vision in a matter of days.
This procedure involves two steps – creating a flap in the cornea, and then using a highly sophisticated laser to shape the bed and thereby remove your spectacle number.
LASIK surgery is extremely safe. All patients we see undergo a thorough eye check-up from A to Z. We look for all possible eye variations which could contribute to spectacle power and any previously undiagnosed eye problems. Some of these tests include detailed evaluation of the true spectacle power by different methods, tests for dry eye, intraocular pressure measurement,Topography,Keratometry, pupil size measurement, and a detailed retinal check-up.
The LASIK procedure is performed by the highly sophisticated Excimer laser – the Allegretto Wavelight by Alcon.
PRK is a similar procedure to LASIK. However, in this surgery, the laser is applied directly to the cornea without creating a flap. This procedure is often the choice of surgery in eyes with thinner corneal profiles.
LASIK and PRK are once-in-a-lifetime procedures, which can provide crystal clear vision. Truly a life-changing experience!
Will it be safe for me in the future?
The surgical procedure is painless and a safe one. Before you undergo the surgery, we perform an exhaustive and comprehensive list of tests and investigations for every refractive patient. The entire check up for the first time may take upto 3-4 hrs including the time for dilatation of your eyes and retinal examination. The test results are then analyzed and interpreted by our Doctor who then discusses with the patient whether it is safe to undergo the surgery.
What if LASIK or PRK is not suitable for me? Can’t I get rid of my glasses?
For the patients whose eyes aren’t suitable for the corneal procedures (LASIK, PRK) we provide other options, which are equally safe and effective. These include like ICL (Implantable Collamer Lens) or IPCL or Refractive Lens Exchange.
ICL AND IPCL
These procedures are an option in patients who are unsuitable for corneal procedures (LASIK, PRK) due to a thin corneal profile or a very high refractive error.
ICL & IPCL can be compared to contact lenses which are worn over the eye. But unlike contact lenses, which require to be worn and removed every day, the ICL and IPCL lenses are surgically implanted directly into the eye. This is a once-in-a-lifetime procedure.
ICL and IPCL can correct very high refractive errors, even those above the reach of LASIK. The surgery is very safe, and in experienced hands, gives excellent results. Unlike other surgeries, it is also completely reversible.
Once the lens is inside my eye, Will it hurt? Will it be seen from the outside?
The ICL or the IPCL are designed to perfectly match the shape of your eye. The lens sits comfortably behind your iris tissue and on top of your natural lens without causing any discomfort. It is not visible to naked eye and can only be seen through a ophthalmic microscope.
What are the precautions I have to undertake after the implantation?
After the surgical procedure routine eye drops will be started. You will need to visit the consultant on day 2, day 7 and then 1 month after the surgery. These visits are important to check the location and the position of the lens inside the eye and to measure the intraocular pressure.
RELEX AND PRELEX
Refractive Lens Exchange (ReLEx) is the name given to the surgery wherein the natural lens of the eye is exchanged with an artificial lens (IOL). Normally this is done when the natural lens becomes cloudy, a condition called cataract. However, when this surgery is done before the development of cataract, in order to remove glass power, it is called ReLEx.
Just as cataract surgery is one of the safest surgeries performed around the world, so is ReLEx. This surgery is especially suitable for patients in the presbyopic age group with very high glass power who cannot undergo LASIK or other procedures. When this kind of lens exchange is done in patients in the presbyopic age (>40yrs) it is referred to as PreLex.
The natural lens is substituted with an artificial intraocular lens (IOLs) like multifocal or trifocal lenses whose optical properties provide the patient with good distance, intermediate and near vision. This reduces the dependency on glasses for everyday work. Occasionally a small power may be required in some patients for fine work, both for distance and near.
Will I need my glasses after surgery?
ReLEx or PreLEx is a surgery done in patients who are absolutely dependent on glasses for all their daily activities and hence want to get rid of them. Once the natural lens is substituted with IOLs like multifocal and trifocal lenses which give excellent vision, the dependency on glasses is greatly reduced. This means that the patient will get good quality vision for both near and distance without wearing glasses. Glasses may be occasionally needed, based on each patient’s individual perception.
At what age can I get this surgery?
You can have this surgery right from the age of 20 years to before the cataract actually develops. It is a procedure which replaces your natural lens with an artificial intraocular lens whose power is calculated according an individual’s eye. It is a customized approach which takes into account the personality of the individual, the nature of his or her profession, and hobbies such as reading, watching television, etc. to give maximum comfort after surgery.
