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, pupil size measurement, and a detailed retinal check-up.

Then we take additional steps to ensure safety, by using the most advanced equipment for eye measurements.

  1. The iTrace - This unique machine works on the principle of ray tracing technology. Aberrations are imperfections in the optical quality of an eye. Some of these (‘lower order aberrations’) can be corrected with spectacles and some (‘higher order aberrations’) cannot. Similarly conventional LASIK laser can only correct the lower order aberrations. For eyes with significant higher order aberrations, we offer Wavefront-guided LASIK, a sophisticated technique that is individualized to that eye.
  2. Pentacam (Oculyzer by Alcon) – This is based on Scheimpflug camera wherein the corneal power is measured at multiple points. These measurements are based on elevation from a reference sphere – a form of elevation-based topography. This helps in assessing the corneal cylinder (astigmatism) and different locations. Unsafe cases like eyes with keratoconus are easily picked up with this test. The Pentacam can also accurately measure thickness of the cornea at various locations, and can determine whether the cornea can safely withstand the laser procedure.


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!

Some FAQs

  1. Will it be safe for me in the future?
    The surgical procedure is painless and a safe one. Before you undergo the surgery, we at Laxmi eye Institute perform an exhaustive and comprehensive list of tests and investigations for every refractive patient. The test results are then analyzed and interpreted by our Refractive Specialists who then discusses with the patient whether it is safe to undergo the surgery.
  2. Do I have to go elsewhere for some of these complicated tests?
    Most of the tests required for a comprehensive refractive workup are based on latest technology and equipment which may not be available everywhere. Fortunately, at Laxmi Eye Institute we have everything under one roof. 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.
  3. Why should I choose Laxmi Eye Institute for undergoing this procedure?
    Laxmi Eye Institute is synonymous with quality eye care, and the team of Refractive Specialist at LEI will strive to give you the best of eye care. To guide you through the process, we have helpful patient coordinators, competent and well-trained technicians, and compassionate counselors who will dispel any doubts you may have. Our experienced and skilled Refractive Specialists will examine you and discuss your reports with you, and indeed, will become your friend by the end of your visit!
  4. 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.
