目的观察超声乳化术治疗白内障的临床有效性和安全性。方法回顾性分析638例(682眼)患者行白内障超声乳化术后的视力改变及眼部并发症情况。结果所有患者成功完成手术并随访1 a。术后第1天视力:>0.3者占90.6%,>0.5者占82.7%;术后3个月视力>0.3者占94.1%,>0.5者占87.4%。人工晶状体植入率为99.9%。主要并发症有术中浅前房9眼,后囊膜破裂13眼;术后早期角膜水肿48眼,色素膜炎3眼;术后中、晚期黄斑囊样水肿2眼,后囊膜混浊35眼;未发生视网膜脱离、核坠落、角膜失代偿、悬韧带断裂、眼内炎性反应等严重并发症。结论白内障超声乳化术难度较大,但只要严格规范操作、正确处理并发症,就能够保证手术效果,术后可获得较好的视力。
Objective To observe the clinical efficacy and safety of phacoemulsification in the treatment of cataract. Methods The visual acuity and ocular complications of 638 patients (682 eyes) undergoing cataract phacoemulsification were retrospectively analyzed. Results All patients successfully completed the operation and were followed up for 1 year. Visual acuity on the first postoperative day:> 0.3 accounted for 90.6%,> 0.5 accounted for 82.7%; 3 months after visual acuity> 0.3 accounted for 94.1%,> 0.5 accounted for 87.4%. Intraocular lens implantation rate was 99.9%. The main complications were intraoperative shallow anterior chamber 9, posterior capsular rupture 13; early postoperative corneal edema 48, 3 melanitis pigmentosa; postoperative middle and late macular cystoid edema 2, posterior capsular opacity 35 Eyes; no serious retinal detachment, nuclear fall, corneal decompensation, suspensory ligament rupture, intraocular inflammatory reaction and other serious complications. Conclusions Cataract phacoemulsification is difficult, but as long as the operation is strictly regulated and the complications are correctly handled, the operation effect can be guaranteed and the better visual acuity can be obtained after operation.
