目的:评价圈垫式劈核在小切口白内障囊外摘除术中的应用.方法:对79眼白内障应用圈垫器和切核刀进行劈核取出,植入后房型人工晶体.观察术中、术后的并发症及术后视力.结果:78眼患者一期囊袋内植入人工晶体,3例眼术中后囊破裂,其中2眼后囊破口小,人工晶体仍植入囊袋内,1眼因后囊破口大,人工晶体于睫状沟植入.术后第1天角膜轻度水肿17眼,占21.5％；中度水肿1眼,占1.3％;一过性高眼压4眼,占5.1％.术后2周视力0.1～0.25者3眼,占3.8％;0.3～1.0者76眼,占96.2％.结论:圈垫式劈核在小切口白内障囊外摘除术中的应用是安全、简便的,且手术成本低,适合在基层医院和大规模白内障复明行动中开展.%Objective:To evaluate the application of chop technique with lens loop-pad in small incision cataract surgery. Methods: Seventy-nine cataract lens were removed with loop-pad and chop knife before implanting posterior chamber intraocular lens, with observation of the intra-and postoperative complications and visual acuity correction after the procedure. Results-. Intraocular lens( IOL) were primarily implanted in capmi-lar bag of 78 eyes. Intraoperative posterior capsule rupture occurred in 3 eyes,in which implantation was successful in 2 eyes owing to posterior capsular smaller laceration and 1 was managed via ciliary sulcus due to larger laceration. Mild cornea edema was seen in the first postoperative day in 17 eyes( 21. 5% ) and moderate edema in I eye( 1. 3% ) .transient high intraocular pressure in 4 eyes(5. 1% ). Visual acuity was corrected after 2 weeks by 0. 1 -0. 25 in 3 eyes( 3.8%) and 0. 3 - 1.0 in 76 eyes (96.2% ). Conclusion: Chop technique with lens loop-pad in small incision cataract surgery can be recommended to community-based hospitals and large scale cataract operation for its safety, simple performance and low cost.
