摘要目的 探讨小切口非超声乳化白内障摘出术中发生后囊破裂人工晶状体一期植入的安全性和有效性.方法 对346例(381眼)行小切口非超声乳化白内障摘出术,术中发生晶状体后囊破裂21眼,其中18眼一期植入后房人工晶状体,3眼未植入人工晶状体,观察后囊破裂人工晶状体一期植入病例的并发症及术后3月视力.结果 一过性眼压升高3眼(16.67%),角膜水肿16眼(88.89%),人工晶状体轻度偏位2眼(11.11%),瞳孔欠圆、轻度移位5眼(27.78%),术后3月最佳矫正视力≥0.5者13眼(72.22%),无严重并发症发生.结论 小切口非超声乳化白内障摘出术中后囊破裂时,视具体情况后房型人工晶状体一期植入是安全的,并可取得较好的视力.

abstractsObjective To study the efficacy and safety of non-phacoemulsification cataract extraction and intraocular lens implantation in the patients with intraoperative posterior capsule rupture. Methods 346 cases (381 eyes) were accepted small-incision non-phacoemulsification cataract surgery and were implanted intraocular lens. 21 cases underwent intraoperative posterior capsule rupture,of which 18 cases were accepted one-stage implantation of posterior chamber intraocular lens, 3 cases didn' t select it. The complications and postoperative visual acuity after follow-up for three months were investigated. Results Transient elevation of intraocular pressure occurred in 3 eyes ( 16. 67% ) , corneal edema in 16 eyes (88. 89% ) ,mild deviation of intraocular lens in 2 eyes ( 11. 11% ) , pupil less round and mild displacement in 5 eyes (27. 78% ). The best corrected visual acuity was more than 0. 5 in 13 eyes (72. 22% ) three months after operation. No serious complications occurred. Conclusion According to specific conditions, this technique of one-stage implantation of non-phacoemulsification intraocular lens is safe and can achieve better vision in the patients with intraoperative posterior capsule rupture during the surgery of non-phacoemulsification.
