LASIK begins with the application of numbing eye drops to ensure comfort. A small flap is created on the cornea using either a microkeratome or a femtosecond laser. This flap is gently lifted to expose the underlying corneal tissue. An excimer laser, which is highly precise and computer-controlled, is then used to reshape the cornea by removing microscopic amounts of tissue. This reshaping corrects the refractive error, allowing light to focus properly on the retina. Once the cornea has been reshaped, the flap is carefully repositioned, where it adheres naturally without stitches. The entire procedure typically takes about 15 minutes per eye, and patients usually notice an improvement in their vision almost immediately.
