Hole in the iris. This procedure is done in order to lower the risk of angle closure in patients with anatomically narrow angles. If the iris and the cornea are in close proximity they may touch and by doing so, block the drainage pathway of the eye. The hole made by the yag laser serves to provide a pathway for fluid to move between the front and back of the eye.
Excellent. This is a curative procedure for narrow angle glaucoma and works very well. It is usually done in both eyes.
Great Prognosis. Irdiotomy for narrow angle glaucoma is usually 100% effective in preventing a glaucoma "attack" from angle closure glaucoma. This is true if the iridotomy is created by a laser or other methods.
See below. YAG iridotomy greatly reduces the chances of developing acute (and chonic) angle-closure glaucoma which can quickly damage one's vision. If your angles are sufficiently narrow, it is recommended that you have this procedure done. Talk to your ophthalmologist.
