目的：分析巨大硬核白内障术中环形撕囊的直径大小,探讨环形撕囊技术的改进及评价环形撕囊联合放射状多点前囊口截开在巨大硬核白内障手术中应用的优点。n 方法：对69例80眼巨大硬核白内障病例,成功施行前囊膜连续环形撕囊联合放射状多点前囊口截开,顺利娩核。结果：顺利完成手术78眼(98%),2眼因巨核挤压,发生后囊膜破裂或部分悬韧带断裂,术中双手法将核旋入前房,或用圈匙将核托入前房后娩出,清理瞳孔区玻璃体,Ⅱ期植入悬吊式人工晶状体。n 结论：环形撕囊技术的改进即连续环形撕囊联合放射状多点前囊口截开在巨大硬核白内障术中应用是安全有效的。%AIM: To analyze huge hardcore cataract surgery with the diameter of the circular capsulorhexis size, discuss circular capsulorhexis technique improvement and evaluate the application advantages of anterior capsule continuous curvilinear capsulorrhexis combined with anterior capsule opening radial multi - point cutting surgery in huge hardcore cataract surgery. n METHODS: Sixty- nine cases(80 eyes ) with huge hardcore cataract, successfully underwent anterior capsule continuous curvilinear capsulorrhexis combined with anterior capsule opening radial multi-point cutting surgery, and delivered nuclear smoothly. n RESULTS: Seventy - eight eyes(98%) successfully completed surgery. Two eyes occurred capsular rupture or part of the suspensory ligament rupture caused by squeezing huge hardcore. Intraoperative, nuclear was spun into the anterior chamber by hands, or dragged into the anterior chamber using circle key and delivered. Pupil vitreous was cleaned up, then suspensory intraocular lens was implanted at second stage. n CONCLUSION: As the improvement surgery of anterior capsule continuous curvilinear capsulorrhexis combined with anterior capsule opening radial multi-point cutting method is safe and effective in huge hardcore cataract surgery.
