Limbal Relaxing Incisions - (Astigmatic Keratotomy)
Limbal Relaxing Incision is a procedure used to correct Astigmatism.
A cornea that has astigmatism (or is “warped”) can be made more round with limbal relaxing incisions. These incisions “relax” the cornea’s steep curvature and improve the way the eye focuses light.
By decreasing the astigmatism, images are clearer and there is a decreased need for glasses or contact lenses. Limbal relaxing incisions (sometimes called peripheral corneal relaxing incisions) are often combined with cataract or other lens-based surgeries.
The Procedure – In Detail
Prior to surgery, the eye is numbed with drops. With an eyelid holder in place to keep the eye steady, Dr. Harvey uses a surgical blade to make one or two tiny cuts around the edge of the cornea. The procedure takes less than five minutes.
The eye heals by itself and bandage contact lenses are rarely needed. Slight irritation and light sensitivity are normal immediately after surgery. Eye drops are needed for several weeks to keep the eye lubricated and promote healing.
The surgery is performed on an outpatient basis so that the patient is able to leave the surgery center the same day. Patients are advised to arrange for someone to drive them to and from surgery.
