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。方法对白内障摘除人工晶体植入术后２４ 例复视患者行视力、眼前节、眼底等常规检查，并进行屈光、眼肌运动、复视像检查，用三棱镜及同视机检查眼位及融合功能，部分患者行眼肌牵拉试验。结果 双眼复视１９ 例中，斜视性复视１７ 例，中枢融合障碍性复视２ 例；斜视性复视中，除３ 例为间歇性外斜视外，其余１４ 例均有不同程度的眼肌运动障碍；单眼复视５ 例中，４ 例为手术后人工晶体偏位所致，１ 例为先天性下方虹膜缺损所致。结论 白内障摘除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，早期经过积极治疗，大部分患者可获得健全的双眼视觉；单眼复视多为手术并发症所致。
Objective To investigate the etiology, mechanism and clinical outcome of diplopia after intraocular lens implantation. Methods Visual acuity, anterior segment and fundus were routinely examined in 24 patients with diplopia after cataract extraction and intraocular lens implantation. Refractive, ocular motions and complex images were examined. Prism and synoptophore Fusion function, some patients underwent eye traction test. Results Among the 19 cases with binocular diplopia, 17 cases were strabismus with diplopia and 2 cases were with central fusion obstructive diplopia. In strabismic double vision, the other 14 cases had different degrees of ophthalmus Dyskinesia; monocular diplopia in 5 cases, 4 cases of postoperative intraocular lens deviation due to one case of congenital inferior iris defect caused. Conclusion Some patients with oculomotor dyskinesia complicated with cataract extraction and intraocular lens implantation are still not clear in their pathogenesis. In the early stage of active cataract surgery, most patients have adequate binocular vision. For monocular diplopia, surgical complications Due.
