老年性过熟期白内障前房灌注连续环形撕囊术

The study of continuous curvilinear anterior capsulorhexis performing on the hypermature stage of senile cataract under anterior filling

目的探讨前房灌注下连续环形撕囊术在老年性过熟期白内障摘出术中的临床使用效果。方法将病例分成观察组(A组)、对照组(B组)。A组:采用自制7号注射器钝针头与普通输液管连接前房灌注液(复方平衡盐溶液,BSS),自左侧前房穿刺口伸入前房,截囊针自右侧前房穿刺口伸入前房,在前房连续灌注下行连续环形撕囊术。B组:用黏弹剂充盈维持前房行连续环形撕囊术。结果A组:100眼中撕囊成功90眼,B组60眼中成功45眼,经χ2检验,两组成功率差异有统计学意义(χ2=0.4,P<0.05)。结论前房灌注下连续环形撕囊术是老年性过熟期白内障摘除术中前囊处理较好方法,操作较简单、成功率高。

Objective To study the effect of continous curvilinear anterior capsulorhexis performing on the hypermature stage of senile cataract under anterior filling. Methods All the cases were divided into normal group（A group）and study group （Bgroup）.In group,A, We used 7 G blunt needle to connect normal perfusion tub and filled anterior chammber with compound equilibrium liquid, blunt needle go into anterior chamber at left puncture,discission needle at right puncture ,the perform continuous curvilinear anterior capsulorhexis under equilibrium liquid,but in group B,we do it under healon. Results In grup A,90 eyes were successful in 100 eyes, but group B,45 syes were successful in 60 eyes, it is significantly different in tow groups through χ^2 checking. Conclusions It is an effective,simple and economical method to CCC under anterior chamber liquid filling in the hypermature stage of senile cataract.
