Nd-YAG后囊切开术治疗继发性白内障的主要缺点是通过破坏后透镜囊而增加了人工晶状体眼视网膜脱离的风险。这在高度近视眼中引起了极大的兴趣，因为人工晶状体眼视网膜脱离的风险增加。对219例继发性白内障患者行后囊抛光术，随访6年以上，观察术中及术后并发症。病例组：眼球长度> 25 mm的近视眼209眼，外伤性白内障10眼，其中24眼初次手术无透镜。于1990 ~ 1995年施行二期白内障手术，平均随访42个月。结果：患者术后视力平均提高4行。术中囊破裂9例（4%）.在35只手术眼中，随访期间发生了一次或多次复发，需要再次抛光（16%），5例最终进行了YAG晶状体囊切开术（2%）。结论：后囊抛光术是治疗再生性继发性白内障的一种低风险手术。特别适用于近视眼，以通过保留后透镜囊来降低人工晶状体视网膜脱离的风险。
Nd-YAG posterior capsulotomy in treatment of secondary cataract has the main disadvantage of increasing the risk for pseudophakic retinal detachment by destroying the posterior lens capsule. This is of great interest in high myopic eyes with an increased risk for pseudophakic retinal detachment. In 219 cases of secondary cataract in our clinic a surgical posterior capsule polishing has been performed and this group was followed up over 6 years looking for intra- and postoperative complications.Patients: The examined group included 209 myopic eyes with a bulbus length > 25 mm and 10 eyes with traumatic cataract; 24 eyes of this group had been primarily operated without a lens. The secondary cataract surgery was performed between 1990 and 1995, and the average follow-up period was 42 months. The intra- and postoperative complications were revealed retrospectively by examination of the patients in our clinic or by interviewing the patients' private doctorsResults: The patients achieved a mean improvement in vision of 4 lines. In 9 cases intraoperative capsule rupture occurred (4 %). In 35 of the operated eyes one or more relapses occurred during the follow-up period that made another polishing necessary (16 %), and in 5 cases YAG capsulotomy was eventually performed (2 %). Pseudophakic retinal detachment occurred in none of the cases.Conclusion: Surgical posterior capsule polishing is a low-risk procedure for treatment of regenerative secondary cataract. It is indicated especially in myopic eyes in order to reduce the risk of pseudophakic retinal detachment by conserving the posterior lens capsule.
