What is LPI laser surgery?
LPI is a laser procedure performed in the office to prevent or treat closed angle glaucoma. What is angle closure glaucoma? The drainage site is found within the “angle” where the iris (the colored part of the eye) and the cornea (the clear covering forming the front of the eye) meet.

There is no recovery time following a laser iridotomy, though your vision may be blurry for a few minutes afterward. You may also experience sensitivity to light for a few days, but prescription eye drops help with this symptom.
What is the success rate of laser iridotomy?
Iridotomy helps to prevent AACG by flattening the convex surface of the iris and widening the angle in patients with relative pupillary block. Success rates of laser iridotomy have been reported to be from 65-76%,7,8 and are relatively low in patients of east Asian descent.
How long does iridotomy surgery take?
Some patients describe the sensation as feeling a slight shock, but this is painless and is quickly completed. About an hour after treatment, the patient’s eye will be examined to measure the reduction in eye pressure. Laser iridotomy takes approximately 10 minutes to complete and is performed on an outpatient basis.

Can LPI cause blindness?
The LPI Dilemma
Most important, it reduces the risk of a future acute angle-closure attack, in which the angle abruptly closes and intraocular pressure rises dramatically, leading to pain, and possibly to blindness if left untreated.
