我院于1994～1997年对30例有广泛虹膜后粘连瞳孔不能散大的白内障患者，在完成角巩膜切口后，作虹膜根部切除，通过虹膜切口，钝针头进入后房，细心分离虹膜后粘连，瞳孔缘作放射状切开，使瞳孔中度散大，有利于截囊、娩核、冲吸皮质及人工晶状体植入。使并发白内障摘出术变得十分容易，也避免了后囊破裂和玻璃体脱出。术后保持圆瞳孔。 In our hospital from 1994 to 1997, 30 cases of cataract patients with extensive iris posterior adhesion pupil could not be enlarged. After the scleral incision was completed, the iris root was resected. After the iris incision and blunt needle were inserted into the posterior chamber, the iris posterior adhesions were carefully separated , Pupil edge for radial incision, the pupil moderate dispersion, is conducive to the cyst, nuclear delivery, flushing cortical and intraocular lens implantation. The complicated cataract extraction surgery has become very easy, but also to avoid the posterior capsule rupture and vitreous prolapse. Keep the pupil after surgery.
