LASIK is a corrective eye procedure designed to free patients from the need for glasses or contacts. LASIK is an acronym for laser-assisted in situ keratomileusis. The surgical procedure permanently changes the shape of the cornea, which is the clear cover over the eyeball. The Food and Drug Administration governs lasers used to perform LASIK vision correction.
Procedure
The LASIK procedure is performed by using a laser or blade to cut the cornea, creating a flap that can be pulled back to reveal the middle portion of the eye. Pulses from the laser vaporize the required portions of the stroma and the flap is replaced.
Considerations
Since contacts affect the natural shape of the cornea, patients preparing to have LASIK surgery should refrain from wearing contacts for two to four weeks prior to the surgery, report doctors at the FDA.
Time Frame
LASIK typically is performed on one eye at a time. Most LASIK procedures take about 30 minutes to complete.
Side Effects
Following LASIK surgery, patients may experience itching or burning, or feel that something is lodged in the eye. Patients are strongly discouraged from rubbing the irritated eye.
Warning
Patients who experience any severe pain or drastic changes in vision following a LASIK procedure should contact their doctor immediately and receive emergency treatment.
Benefits
The Eye Surgery Education Council reports that LASIK can be useful for athletes, mothers and frequent travelers who may experience difficulty in keeping up with contacts and glasses.
