LASIK, which stands for laser-assisted in situ keratomileusis, is a type of refractive eye surgery designed to correct vision problems such as myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism. Using a laser to reshape the cornea—the clear front part of the eye—LASIK allows light entering the eye to be properly focused onto the retina, resulting in clearer vision. Renowned consultant ophthalmic surgeon Mr Avi Kulkarni provides the answers to commonly asked questions about the LASIK, helping you to make an informed decision before undergoing the surgery.
How does LASIK work?
LASIK involves creating a thin flap in the cornea, which is then carefully lifted to permit an excimer laser to reshape the underlying corneal tissue. The laser precisely removes microscopic amounts of tissue to alter the cornea's curvature. Once the reshaping is complete, the flap is laid back in place, acting as a natural bandage for the healing process.
Am I a good candidate for LASIK?
LASIK isn’t appropriate for everyone. Suitable candidates are usually adults over 18 who have had a stable prescription for at least a year. Good overall eye health is essential, meaning conditions like glaucoma, cataracts, and certain corneal diseases might preclude one from undergoing the procedure. A thorough pre-operative examination by your ophthalmologist will determine your suitability.
What are the benefits of LASIK?
One of the primary benefits of LASIK is the significant improvement in vision, often eliminating the need for glasses or contact lenses. Many patients achieve 20/20 vision. The procedure is relatively quick, typically lasting around 15 minutes for both eyes, with minimal discomfort due to numbing eye drops. Recovery is also swift, with most patients experiencing improved vision within 24 hours.
Are there risks associated with LASIK?
As is the case with any surgical procedure, LASIK carries potential risks and complications. Some patients might experience dry eyes, glare, halos around lights, or fluctuating vision in the initial healing period. These side effects are usually temporary, but in rare cases, they can persist. Serious complications are infrequent, but it is essential to discuss all potential risks with your ophthalmologist.
How should I prepare for LASIK?
Preparation for LASIK involves a comprehensive eye examination to ensure your eyes are healthy and to measure the cornea's shape and thickness. You should stop wearing contact lenses a few weeks before the surgery as they can alter the cornea's shape. Additionally, you should arrange for someone to drive you home after the procedure, as your vision might be blurry immediately following the surgery.
What can I expect during recovery?
Post-operative care is crucial for a successful outcome. Your ophthalmologist will provide specific instructions, which might include using prescribed eye drops to prevent infection and inflammation, avoiding strenuous activities, and not rubbing your eyes. Follow-up appointments will be scheduled to monitor your healing and ensure your vision is improving as expected.
LASIK eye surgery can offer a life-changing improvement in vision. By understanding the procedure, assessing candidacy, and following pre- and post-operative guidelines, you can make an informed decision about whether LASIK is right for you.
