What is the procedure called where a portion of the iris is surgically removed?

The procedure where a portion of the iris is surgically removed is known as an iridectomy. This surgical technique is typically performed to treat various conditions affecting the eye, such as glaucoma, where reducing intraocular pressure is necessary, or to remove pathological tissue. During an iridectomy, a surgeon excises a section of the iris, which can facilitate the drainage of aqueous humor and help manage the pressure within the eye.

In contrast, iris resection is not the standardized terminology widely used; it may be confused with iridectomy. Lens extraction involves the removal of the lens of the eye, often due to cataracts, and does not pertain to the iris. Corneal transplantation involves replacing a damaged or diseased cornea with healthy donor tissue, which again is unrelated to iris procedures. Understanding the distinctions among these surgical terms is essential for clarity in ocular surgeries.
