人工晶体植入术后复视的临床分析

目的　探讨白内障摘除人工晶体植入术后复视的发病原因、机制及临床转归。方法　对人工晶体植入术后所有复视患者行视力、眼前节、眼底常规检查 ,并进行屈光、眼肌运动、复像检查 ,用三棱镜及同视机检查眼位及融合功能。结果　在双眼复视 8例中 ,斜视性复视 7例 ,中枢融合障碍性复视 1例。单眼复视 4例是术后人工晶体偏位所致。结论　人工晶体植入术后部分患者合并眼肌运动障碍性复视 ,其发病机制尚不明确 ,经早期积极治疗 ,多数患者可获得双眼视觉。单眼复视多为手术并发症所致。

A Clinical Analysis of the Diplopia after Intraocular Lens Implantation

Objective To investigate the pathogenesis, mech anism and prognosis of diplopia after cataract extraction with intraocular lens implantation.Me thods Besides routine ocular examinations, refraction, ocular position, ocular movemen t, fusional function and image of diplopia were examined on all the patients.Results Among 8 cases with binocular diplopia, there were 7 cases of strabismic d iplopia and 1 case of diplopia due to central fusional impairment. Monocular dip lopia 4 cases were resulted from operative complication.Conclusion The pathoge nesis of strabismic diplopia resulted from dysfunction of ocuar movement is unkn own. Most of the patients can obtain binocular vision by early active treatment. Monocular diplopia is mostly resulted from operative complication.
