An iridectomy, also known as a surgical iridectomy or correctomy, is the surgical removal of part of the iris.[1][2] These procedures are most frequently performed in the treatment of closed-angle glaucoma and iris melanoma.[2]

Comparison with Nd:YAG laser iridotomy[edit]

In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer. Opening the globe for a surgical iridectomy in a patient with high intraocular pressure greatly increases the risk of suprachoroidal hemorrhage, with potential for associated expulsive hemorrhage. Nd:YAG laser iridotomy avoids such a catastrophe by laser created hole in the iris, which facilitates flow of aqueous humor from the posterior to the anterior chamber of the eye.

Current indications[edit]

Surgical iridectomy is commonly indicated and performed in the following cases:
