白内障超声乳化手术中的玻璃体脱出探讨

Viteous prolapse during phacoemulsification.

本文对白内障超声乳化手术中后囊破裂的发生及有关因素进行了分析。方法：统计白内障超声乳化手术９８１只眼（平均年龄６０９岁），按手术进程分别记录后囊破裂，玻璃体外溢发生的有关情况探讨。结果：发生后囊破裂者２７只眼（２７５％），合并玻璃体外溢者２４只眼（２４５％），其中与撕囊有关的后囊膜破损４只眼（１４８％），超声乳化过程中发生后囊破损１４只眼（５１９％），抽吸皮质２只眼（７４％），人工晶体植入造成后囊破损２只眼（７４％），囊袋脱位５只眼（１８５％）。结论：防止术中后囊破裂并提高处理能力，对于提高手术成功率和手术后效果非常重要。

To analyze the incidence and related factors of posterior capsular rupture (PCR) in phacoemulsification.Metheds The PCR and vitreous loss was recorded according to the stage of operative procedure in 981 eyes with cataract (the average age was 60 9 years).Results There were 27 eyes (2 75%) with PCR and 24 eyes (2 45%) of thew, accompanied with Vitreous loss.The PCR in 4 eyes (14 8%) occurred with capsulotomy,14 eyes( 51 9%) occurred during phaco,2 eyes (7 4%) in the course of aspiration of the cortex,2 eyes (7 4%) damage to the postererior capsule in IOL implantation,and 5 eyes (18 5%) with Ionular break.Conclusion Intraoperatively,the prevention of PCR and improvement of management ability are Very important.
