AIMS
The aims of this study were to report the surgical and visual outcomes of posterior polar cataract and to assess the risk factors for posterior capsule rupture.
METHOD
Medical records of 81 eyes of 59 patients were reviewed. The surgical procedure used, intraoperative complications and postoperative visual outcome were recorded.
RESULTS
Of the 81 eyes, 61 eyes (75%) underwent phacoemulsification. Seventeen eyes had extra-capsular cataract extraction, and manual small incision cataract surgery was performed on three eyes. Posterior capsule rupture occurred in 25 (31%) eyes: it was more common in young patients (<40 years) and in the extra-capsular cataract extraction group. Two eyes had nucleus drop during phacoemulsification. The postoperative visual acuity was >or=20/30 in 76 eyes.
CONCLUSION
Posterior capsule rupture occurred more frequently in extra-capsular cataract extraction compared with phacoemulsification and in patients below 40 years of age. Phacoemulsification, done carefully, leads to good visual outcome.
目的
本研究的目的是报告后极性白内障的手术及视觉效果，并评估后囊破裂的危险因素。
方法
回顾了59例患者81只眼的病历。记录所采用的手术方式、术中并发症及术后视觉效果。
结果
81只眼中，61只眼（75%）接受了超声乳化白内障吸除术。17只眼行囊外白内障摘除术，3只眼行手法小切口白内障手术。25只眼（31%）发生后囊破裂：在年轻患者（<40岁）及囊外白内障摘除术组中更常见。2只眼在超声乳化白内障吸除术中发生核脱失。76只眼术后视力≥20/30。
结论
与超声乳化白内障吸除术相比，囊外白内障摘除术后囊破裂更常见，且在40岁以下患者中更常见。仔细进行超声乳化白内障吸除术可获得良好的视觉效果。
