Helpful Definition for: LASIK Eye Surgery, Surgeons And Centers
LASIK is a type of surgical procedure that uses an excimer laser to permanently alter the shape of the cornea (the clear covering at the front of the eye). For many patients, LASIK can be a viable alternative to wearing glasses or contact lenses. The procedure involves three steps: making a thin flap on the eye, folding it so that the underlying tissue can be reshaped with the laser, and then repositioning the flap so that the eye can heal. The surgery is done with the patient awake using anesthetic eye drops and, sometimes, a mild sedative. Post-operative care includes a course of antibiotics and eye drops, protective goggles to prevent accidental rubbing of the eyes, and shields to prevent exposure to bright light; patients must adhere strictly to post-op instructions to reduce the risk of complications. Many patients report great satisfaction with LASIK; however, all surgeries present the risk for complications. The most common post-LASIK complaint is dry eyes; others include experiencing halos, light sensitivity, double vision and over- or under-correction of the original condition.
