目的 :探讨在白内障超声乳化术中行前囊膜抛光处理减少后发障发生的有效性和安全性。方法 :178例 (2 35只眼 )白内障患者在施行白内障超声乳化吸除及人工晶状体植入术中进行前囊膜抛光 ,术后对其视力、眼前节反应及后囊膜情况进行临床观察 ,随访 1个月～ 1年 ,选择同期未行前囊膜抛光者 2 2 0例 (2 30只眼 ) ,作为对照组进行比较。结果 :(1)术中无并发症发生 ;(2 )术后视力恢复快而良好 ;(3)术后后囊膜混浊发生 8只眼 (3 5 % ) ,均为轻度纤维型混浊 ,对视力无显著影响 ,而对照组术后后囊膜混浊发生 2 3只眼 (10 2 % )。对照组显著高于抛光组 (P <0 0 5 )。结论 :白内障超声乳化术中行前囊膜抛光处理可以减少术后后囊膜混浊的发生。作用机制可能是 :前囊膜抛光可大幅度地减少残留于前囊下的晶状体上皮细胞数量 ,阻止了上皮细胞的增殖及化生的来源 ,从而起到防止后囊膜混浊发生的作用
Objective: To investigate the effectiveness and safety of the onset of cataract in cataract phacoemulsification with the reduction of anterior capsule polishing. Methods: A total of 178 patients (235 eyes) with cataract were subjected to anterior capsulotomy during phacoemulsification and intraocular lens implantation. Visual acuity, anterior segment reaction and posterior capsule were observed after operation. During follow-up of 1 month to 1 year, 220 cases (230 eyes) who did not undergo anterior capsule polishing during the same period were selected as the control group for comparison. Results: (1) no intraoperative complications occurred; (2) visual acuity recovered quickly and well; (3) ocular posterior capsule opacification occurred in 8 eyes (35%), all of which were mild fibrosis, No significant effect on visual acuity, while the control group posterior capsular opacification occurred in 23 eyes (102%). The control group was significantly higher than the polished group (P <0 05). Conclusion: Cataract phacoemulsification before anterior capsule polishing can reduce postoperative posterior capsular opacification. The mechanism may be: anterior capsular polishing can significantly reduce the number of residual epithelial cells in the anterior capsule, prevent the proliferation of epithelial cells and the source of metaplasia, which play a role in preventing the occurrence of posterior capsular opacification
