Lasik is a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. In LASIK, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser.
- It is a daycare procedure which is painless, safe, and with fast recovery of vision. It the most popular procedure for laser vision correction.
- The patient is prepared before the procedure with anesthetic and antibiotic eye drops, making the eye numb and sterile for the laser procedure.
- A Microkeratome or a Femtosecond laser handpiece-is used to create a thin corneal flap which remains hinged through the procedure.
- The corneal flap is lifted and the inner layers of the cornea are “Lasered” with a excimer laser to reshape the inner layer of the cornea assisted by an active eye tracking system , tracking eye movements and directing the laser accordingly. The laser algorithms or treatment plans are computer calculated and driven to give an accurate outcome.
- The flap is then replaced without the need for stitches, the entire LASIK procedure thus finishes within few minutes.
