摘　　要：目的　了解白内障摘除及人工晶体植入术后患者的立体视觉及其影响因素。方法　对 3 0名白内障摘除及人工晶体植入术后裸眼视力≥ 0 .5患者进行立体视锐度、抑制暗点、双眼屈光度差和视像不等的检查。结果该组白内障摘除及人工晶体植入术后患者的立体视锐度为 40 7.67″± 3 90 .19″,双眼屈光度差为 1.5 3 D± 1.96D,视像不等为 3 .93 %± 3 .5 1% ,抑制暗点为 3 .17°± 1.98°。立体视锐度与双眼屈光度差或视像不等之间无明显相关关系 ,立体视锐度与抑制暗点呈正相关。结论　人工晶体植入可较大程度减小白内障术后无晶体眼的双眼屈光度差、视像不等 。Objective To understand the stereopsis of the patients after cataract extractation and intraocular lens implantation and the related factors. Methods In this study were examined the stereopsis of 30 patients who had undergone cataract extraction and intraocular lens implantation and whose post-operative vision acuity measurements were 0.5 or higher. Results These patients' steroacuity, anisometropia, aniseikonia and scotoma were: 407.67' ±390.19', 1.53D±1.96D, 3.93%±3.51%, 3.17″±1.98″ respectively. There was no significant correlation between steroacuity anisometropia and aniseikonia. There was siganificant positive correlation between steroacuity and scotoma. Conclusions Intraocular lens implantation may ameliorate anisometropia and aniseikonia of the patients after cataract extraction and reduce the damage to stereopsis.
