What is Laser Iridotomy?
Laser iridotomy is used when the drainage angle is dangerously narrow or at risk of closing. The laser creates a tiny opening in the iris so fluid can move more safely through the front of the eye and reduce the chance of an angle-closure attack.

If you are diagnosed with narrow angle glaucoma, an ophthalmologist may perform a procedure called laser iridotomy, to decrease the risk of a sudden and dangerous build-up of pressure in your eye. Before the procedure, they will place drops in your eye to constrict the pupil. Then, using a precisely focused beam of laser light, the ophthalmologist will create a tiny hole in your iris. This hole acts as an alternate channel through which fluid inside the eye can flow, if the usual pathway becomes blocked. Soon after the procedure is completed, you may return to your normal activities. Though a laser iridotomy is sometimes performed to relieve a sudden build-up of pressure in your eye that is already underway, it is much more commonly recommended as a preventive measure, before there are any symptoms at all.
