目的 :探讨后囊膜保护垫在超声乳化白内障吸除术中的应用。方法 :手术中采用自制的囊膜保护垫置于晶状体核下方 ,然后进行晶状体核的超声乳化。结果 :46只眼中 ,无一例因为碎核、劈核和核碎片的超声乳化发生后囊膜破裂。术后3个月矫正视力≥ 0 8者 ,占 6 7 39%。轻度角膜水肿 5例 ,中度角膜水肿 2例。抽吸皮质时后囊膜破裂 1例。结论 :采用晶状体后囊膜保护垫能防止晶状体核超声乳化时后囊膜破裂 ,缩短超声乳化技术的学习曲线 ,减少学习早期的手术并发症 Objective: To investigate the application of posterior capsule protector in phacoemulsification cataract surgery. METHODS: A self-made capsule protector was placed under the nucleus of the nucleus during the procedure, followed by phacoemulsification of the nucleus of the lens. RESULTS: Of the 46 eyes, none had ruptured posterior capsule due to phacoemulsification of disruption, nuclear cleavage, and nuclear fragmentation. 3 months after correction of visual acuity ≥ 0 8, accounting for 6 7 39%. 5 cases of mild corneal edema, 2 cases of moderate corneal edema. One case of rupture of posterior capsule when aspirated cortex. Conclusion: The posterior capsule protector can prevent the rupture of posterior capsular capsule during phacoemulsification and shorten the learning curve of phacoemulsification, and reduce the complication of early surgical complications
