Surgery of the iris is of essential importance in anterior segment surgery. In angle closure glaucoma a peripheral iridectomy performed early enough, when the trabeculum is not yet altered, is curative. In simple glaucoma if a filtering operation is performed, the iridectomy is fundamental in order to have a good communication between the posterior chamber and the filtering bleb and to avoid iris incarceration into the filtering wound. In cataract surgery iridectomy is mandatory, especially in intracapsular extraction. In penetrating corneal grafts a patent iridotomy or iridectomy, or several, is a safety factor avoiding the consequences of pupillary block, anterior synechiae and irreducible mydriasis. Another important problem is the surgery of the iris for optical purposes. Other indications which are not discussed in this paper are trauma of the anterior segment of the eye, the removal of benign or malignant tumors, epithelial cysts etc.
虹膜手术在前节手术中至关重要。在闭角型青光眼中，若小梁尚未改变，尽早施行周边虹膜切除术可治愈疾病。在单纯性青光眼中，若进行滤过手术，虹膜切除术是基础，以便后房与滤过泡之间有良好的沟通，并避免虹膜嵌顿于滤过伤口。在白内障手术中，虹膜切除术是必需的，尤其是在囊内摘除术中。在穿透性角膜移植术中，一个或多个通畅的虹膜切开术或虹膜切除术是一个安全因素，可避免瞳孔阻滞、虹膜前粘连和不可复性瞳孔散大的后果。另一个重要问题是出于光学目的的虹膜手术。本文未讨论的其他适应证包括眼前段创伤、良性或恶性肿瘤切除、上皮囊肿等。
