后囊连续环形撕囊治疗超声乳化术中后囊破裂的疗效观察

目的：：观察白内障超声乳化术中出现后囊破裂行后囊连续环形撕囊( PCCC)的临床效果。方法：对2013-03/10的38例38眼年龄相关性白内障患者行白内障超声乳化，术中出现后囊破裂的患者行后囊连续环形撕囊联合人工晶状体植入术；同期随机选择50例50眼年龄相关性白内障患者行白内障超声乳化联合人工晶状体植入术作为对照组，比较两组患者术后视力及其术后并发症情况，随访3 mo。结果：两组患者术后第1d视力、角膜水肿差异有统计学意义(P<0.05)，术后3mo视力及角膜水肿差异无统计学意义(P>0.05)；术后第1d眼压升高差异无统计学意义(P>0.05)，术后3mo瞳孔及黄斑囊样水肿、视网膜脱离差异无统计学意义。结论：对于超声乳化术中发生后囊破裂的患者术中及时使用后囊连续环形撕除，能减少术后并发症发生，有效提高白内障术后效果。

Clinical application of posterior continuous curvilinear capsulorhexis of posterior capsular rupture in the phacoemulsification

AIM: To observe the clinical effect of posterior continuous curvilinear capsulorhexis(PCCC)in phacoemulsification with posterior capsular rupture.

METHODS: Thrity-eight age-related cataract patients(38 eyes)from March 2013 to October 2013 were selected as experimental group and 50 age-related cataract patients(50 eyes)from March 2013 to October 2013 as control group. In experimental group, PCCC were used in the intraoperative posterior capsule tears in phacoemulsification. And in control group phacoemulsification was applied. The visual acuity and surgical complications were compared between two groups, the follow-up period was continued to 3mo after operation.

RESULTS: The visual acuity and corneal edema in two groups had statistically significant(P<0.05)at 1d after operation. Three months after operation, the visual acuity and corneal edema in two groups was not statistically significant(P>0.05). At 1d after operation, the intraocular pressure in two groups was not statistically significant(P>0.05). Three months after operation, the pupil and cystoid macular edema, retinal detachment in two groups was not statistically significant(P>0.05).

CONCLUSION: PCCC can improve the therapeutic effect and prevent surgical complications for phacoemulsification with posterior capsular rupture.
