Limbal Relaxing Incisions (LRI) are an office or operating room procedure to correct for astigmatism. Astigmatism is an optical problem usually due to the cornea not being round but oval, like the shape of a spoon. This results in the patient’s vision being out of focus. A LRI is performed with a diamond knife under a topical anesthetic.  It takes about 5 minutes and is virtually painless.  Two incisions are made at the edge of the cornea. The incisions change the shape of the cornea to make it round and not oval.  The result is clearer vision.

This procedure can be used in conjunction with cataract surgery or on its own. Postop the patient may have a red eye for 3 to 5 days.  The vision improves in 48 hours.
