目的 :讨论白内障囊外摘除、超声乳化摘除及针吸摘除术中后囊膜破裂时行后囊膜连续曲线形撕囊术 (posterior continuouscurvilinearcapsulorhexis,PCCC)的方法和作用。方法 :利用撕囊镊对 10例 (10眼 )白内障摘除术中后囊膜破裂眼行 PCCC,5例联合行前段玻璃体切除术。结果 :10例后囊膜破裂后行 PCCC眼 9例成功完成 PCCC,10例均植入后房型人工晶体。术后观察1月～ 3年 (平均 16月 ) ,9例行 PCCC眼视轴均清晰 ,未发生视网膜脱离及后发性白内障 ,无明显的人工晶体光学部偏中心或人工晶体异位。结论 :PCCC可有效避免后囊膜破孔进一步无限放射状撕裂 ,保持周边后囊膜的完整性 ,使人工晶体稳固于囊袋内
Objective: To discuss the method and effect of posterior continuous curvilinear capsulorhexis (PCCC) in extracapsular cataract extraction, phacoemulsification and needle aspiration ablation. Methods: The use of capsulotomy forceps in 10 cases (10 eyes) cataract extraction in the posterior capsular rupture eyes PCCC, 5 cases of combined anterior vitrectomy. Results: Nine patients with PCCC after the rupture of the posterior capsule were successfully treated with PCCC. All posterior chamber intraocular lenses were implanted in 10 patients. Postoperative observation of January to 3 years (mean 16 months), 9 cases of PCCC ocular axis were clear, no retinal detachment and recurrent cataract, no obvious deviation of intraocular lens or intraocular lens optics. Conclusion: PCCC can effectively avoid further radial tear of posterior capsular rupture, and maintain the integrity of the peri-posterior capsular membrane so that the intraocular lens is stable in the capsular bag
