高度近视白内障超声乳化及低度数人工晶状体植入术

目的：评价高度近视白内障超声乳化及低度数人工晶状体植入术的疗效。方法：对84例128眼高度近视白内障施行巩膜隧道切口超声乳化，乳化时间平均201s，超声能量平均33．85，结果：术后1d,1wk,1mo视力≥0．4者分别为71．1％、75．8％、79．7％，术后3mo视力≥1．0者占22．6％，影响术后视力主要原因为高度近视近致眼底病变，主要并发症为角膜水肿（4．7％）、前房纤维素性渗出（1．65）及后囊膜破裂（2．3％），结论：高度近视白内障超声乳化及低度数人工晶状体植入术，具有视力恢复良好、矫正屈光不正及预防视网膜脱离等优点，是高度近视白内障较理想的手术方式。

Phacoemulsification andlow powered posterior chamber intraocular lens implantation in high myopia cataract

Objective To evaluate the clinical effect of phacoemulsification and low powered posterior chamber intraocular lens implantation in high myopia Methods Phacoemulsification was performed on 128 eyes of 84 patients with cataract in high myopia through scleral tunnel incision Average phaco time was 201s and ultrasonic energy was 33 8% Results The visual acuity 0 4 or better on the first day, in the first week and first month after the operations was in 71 1%,75 8%,79 7%respectively Three months after surgery, 22 6% reached the vision of 1 0 The main cause of the poor result is due to the pathologic changes of the fundus in high myopia The major complications were corneal edema (4 3%), fibrinous exudate in anterior chamber (1 6%) and rupture of posterior capsule (2 3%) Conclusion Phacoemulsification and low powered posterior chamber intraocular lens implantation offers advantages of better rehabilitation of visual acuity, proper correction of ametropia, prevention of retinal detachment and is an unitable technique for highly myopia cataract patients
