周边虹膜切除通常是由结膜瓣下作一小巩膜切口。其缺点包括出血、虹膜不脱出的情况下,很难以镊子从切口深处抓住。结膜瓣会引起疤痕,妨碍将来的引流术。早期的术后并发症包括前房浅,持续性结膜下瘘,前房出血。Phillips和Snow曾研究预防性虹膜切除术后的后粘连发生率及其原因。Lowe和Floman曾观察到虹膜切除术后,晶体发生后期混浊及其对视力的影响,经角膜切口作周边虹膜切除,免除了操作上的困难。随着手术显微镜的广泛使用,经角膜切口作虹膜切除成为合理的手术方法。作者 Peripheral iridotomy is usually performed with a small scleral incision made from the conjunctival flap. The disadvantages include bleeding, iris does not prolapse circumstances, it is difficult to grasp with forceps deep incision. Conjunctival flap can cause scarring, preventing future drainage. Early postoperative complications include shallow anterior chamber, persistent subconjunctival fistula, and anterior chamber hemorrhage. Phillips and Snow studied the incidence of post-prophylactic adhesions and their causes. Lowe and Floman have observed late ophthalmology after ophthalmotomy, opacity and its effect on visual acuity, peripheral iridectomy via the corneal incision, eliminating the operational difficulties. With the widespread use of surgical microscopes, iris resection through the corneal incision has become a reasonable surgical method. Author
