What is the technique called that involves tearing a circular opening in the anterior capsule during cataract surgery?

The technique that involves tearing a circular opening in the anterior capsule during cataract surgery is known as capsulorhexis. This procedure is crucial in cataract surgery as it allows the surgeon to create a controlled opening in the lens capsule that surrounds the cataractous lens. This circular tear enables access to the lens material for its removal while preserving the integrity of the remaining capsule, which is important for the placement of an intraocular lens (IOL) after the cataract has been extracted.

Capsulorhexis is typically performed with a specialized surgical instrument, and its careful execution is vital for a successful cataract surgery outcome. The size and shape of the capsulorhexis can impact the positioning of the IOL and the overall stability of the surgical site throughout healing.

Other surgical terms mentioned, such as iridectomy, refer to the removal of a portion of the iris, and cataract extraction generally describes the overall procedure of removing the cataract but does not specify the technique used for the capsule. Capsulotomy is typically used to refer to an incision after cataract surgery, often during procedures to address complications related to capsule opacification, which emphasizes the importance of understanding the specific definitions and uses of each term in
