目的探讨撕膜技术在小瞳孔白内障手术中的安全性和有效性。方法32只眼小瞳孔白内障,其中14只眼为陈旧虹膜睫状体炎,18只眼为抗青光眼术后,用撕囊镊撕除瞳孔区机化膜,连续环形撕开前囊,囊袋内植入人工晶体,观察手术并发症和术后视力,观察时间为术后3月。结果术后视力较术前明显提高,脱盲率为90%,脱残率70.9%,无严重并发症发生。结论本手术方法对小瞳孔并发白内障有良好的疗效,手术损伤小,不伤及虹膜,术后前节反应轻,值得推广。
Objective To investigate the safety and effectiveness of tearing technique in small pupil cataract surgery. Methods Thirty-two eyes with small pupil cataract, of which 14 eyes were obsolete iridocyclitis and 18 eyes were treated with anti-glaucoma surgery. The capsulorhexis was removed by torn forceps and the peritoneum was continuously torn open. Intraocular lens implantation, observation of surgical complications and postoperative visual acuity, observation time for 3 months after surgery. Results Postoperative visual acuity was significantly higher than before surgery, the blindness rate was 90%, disability rate 70.9%, no serious complications. Conclusion The operation method has a good curative effect on small pupil with cataract. The operation is small and does not hurt the iris. The anterior segment of postoperative reaction is light and worth promoting.
