摘　　要：目的了解探讨白内障超声乳化摘除联合折叠型人工晶体囊袋内植入术后患者的双眼单视功能,以及人工晶体植入术后对双眼影像不等的影响、患者保持双眼单视功能所允许的像差程度和范围。方法随机抽取了术后视力在0.7以上的29例白内障超声乳化摘除联合折叠型人工晶体囊袋内植入术后患者,年龄41～74岁,按双侧或单侧人工晶体眼分成A、B两组;术后一周应用刘蔼年编《双眼影像不等检查图》检测患者的双眼单视功能和双眼影像不等的程度,并分别与正常眼以及两组之间进行比较。结果除B组3例患者没有立体视外,其余患者均有Ⅲ级双眼单视功能。且两组间的各级影像不等像差值无统计学差异(P>0.05)。与正常眼相比,A和B组的Ⅰ级同时视和Ⅱ级融合功能的双眼影像不等像差值均无统计学差异(P>0.05),Ⅲ级立体视功能的双眼影像不等值与正常对照有显著性差异(P<0.01),可能因3例单侧人工晶体无立体视有关。结论白内障超声乳化摘除联合囊袋内植入的人工晶体,除了获得良好的视力恢复外,并获得正常的Ⅲ级双眼单视功能,不引起Ⅲ级视功能的像差异常改变,是极理想的手术方式。Objective To investigate the degree and the range of aniseikonia to restore binocular vision in patients who have undergone phacoemulsification and foldable intraocular lens(IOL)implantation.Methods 29 patients aged between 47 and71 years who underwent phacoemulsification and foldable IOL implantation and had a postoperative visual acuity of batter than 0.7 were randomly collected.Patients were divided into two groups according to bilateral or unilateral pseudophakia.Anisekonia and binocular vision were evaluated a week postoperatively with binocular aniseikonia test charts designed by Liu Ainian.The results of both groups were compared with normal values respectively and between groups.Results All patients had stereoacuity except 3 cases in the unilaterally pseudophakic group.The differences of the degree of aniseikonia in simultaneous perception,fusion and stereoacuity were not statistically significant between groups(P>0.05).There were no statistically significant differences between bilaterally or unilaterally pseudophakic group and normal values in the degree of aniseikonia in simultaneous perception and fusion(P>0.05).Otherwise,there was a significant difference in the degree of aniseikonia in stereoacuity(P<0.01).Maybe about with there were 3 cases unilateral pseudophakia stereoaesthesia.Conclusions Phacoemulsification and foldable IOL implantation is a satisfactory surgical approach with favourable postoperative binocular vision and little change in binocular aniseikonia.
