Iridectomy

Iridectomy, also known as a corectomy, is a surgical procedure that involves the removal of a portion of the iris, the colored part of the eye. This procedure is typically performed to treat various eye conditions, such as glaucoma and melanoma of the iris.

Procedure

An iridectomy can be performed as a traditional surgical procedure or as a laser procedure. In a traditional surgical iridectomy, a small incision is made in the cornea or the sclera. A portion of the iris is then removed through this incision. In a laser iridectomy, a laser is used to create a hole in the iris, allowing fluid to flow more freely within the eye.

Indications

Iridectomy is most commonly performed to treat glaucoma, a condition that increases pressure within the eye and can lead to vision loss. By removing a portion of the iris, the flow of fluid within the eye can be improved, reducing pressure.

Iridectomy may also be performed to treat a melanoma of the iris. In this case, the portion of the iris containing the tumor is removed in an attempt to prevent the spread of cancer.

Risks and Complications

As with any surgical procedure, there are risks associated with an iridectomy. These may include infection, bleeding, and damage to other structures within the eye. There is also a risk that the procedure will not successfully reduce eye pressure or halt the progression of a melanoma.
