LASIK
LASIK EYE SURGERY – A PATH TO BETTER VISION
LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a popular surgical procedure used to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The goal of LASIK is to reduce or eliminate the need for glasses or contact lenses by reshaping the cornea, the clear front part of the eye, so that light entering the eye is properly focused onto the retina. LASIK surgery has become a widely embraced and effective solution for individuals seeking freedom from glasses or contact lenses. Its popularity stems from its quick and relatively painless nature, with many patients experiencing improved vision almost immediately after the procedure. By reshaping the cornea, LASIK addresses common refractive errors such as myopia, hyperopia, and astigmatism. The creation of a corneal flap, achieved either with a microkeratome or femtosecond laser, allows for precise access to the cornea for reshaping.
Preoperative Examination:
Before undergoing LASIK, a comprehensive eye examination is conducted to determine your candidacy for the procedure. Factors such as the thickness of your cornea, the size of your pupils, and the overall health of your eyes will be assessed.
Creation of a Flap:
During the LASIK procedure, a thin flap is created on the cornea using a microkeratome or a femtosecond laser. The surgeon lifts this flap to access the underlying corneal tissue.
Reshaping the Cornea:
The cornea is then reshaped using an excimer laser. The laser precisely removes small amounts of corneal tissue, altering its shape to correct the refractive error.
Flap Repositioning:
After the cornea has been reshaped, the flap is carefully repositioned. It begins to adhere without the need for stitches.
Recovery:
Patients typically experience improved vision almost immediately after the procedure, with minimal discomfort. However, it may take a few days to weeks for vision to stabilize fully.
Postoperative Care:
Patients are given specific instructions for postoperative care, including the use of prescribed eye drops to aid in the healing process.
LASIK has a high success rate, and many people achieve significant improvements in their vision without the need for glasses or contacts. However, not everyone is a suitable candidate for LASIK, and it's important to discuss your individual circumstances with an eye care professional to determine the most appropriate treatment for you. It's worth noting that while LASIK is a commonly performed and safe procedure, like any surgery, it comes with potential risks and complications. Some people may experience dry eyes, glare, halos, or difficulty with night vision after LASIK. Additionally, the long-term effects of LASIK are not yet fully understood, and individual outcomes can vary. It's crucial to have realistic expectations and thoroughly discuss the benefits and risks with your eye surgeon before deciding to undergo LASIK.
