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 binocular monoscopic function of patients after cataract phacoemulsification combined with folding intraocular lens implantation and the effect of intraocular lens implantation on the images of both eyes. Aberration and extent. Methods Twenty-nine patients with postoperative visual acuity of 0.7 or more underwent phacoemulsification and foldable intraocular lens implantation were enrolled. The patients were 41-74 years old and were divided into A and B according to bilateral or unilateral intraocular lens Two groups; one week after the application of Liu Ai, editor of “binocular image unequal examination map” to detect binocular binocular vision and binocular vision range, and were compared with normal eyes and between the two groups. Results In addition to the three patients in group B did not have stereopsis, the other patients had grade Ⅲ Binocular vision function. There was no significant difference between the two groups at different levels of image disparity (P> 0.05). Compared with the normal eyes, there was no significant difference in the disparity between binocular images of class Ⅰ and class Ⅱ fusion in group A and group B (P> 0.05), and the binocular images of class Ⅲ stereoscopic function were unequal There was a significant difference with the normal control (P <0.01), which may be due to 3 cases of unilateral stereotactic intraocular lens related. Conclusions Cataract phacoemulsification combined with intraocular lens implantation in the capsular bag, in addition to obtaining good visual acuity recovery, and to obtain the normal binocular binocular single vision function does not cause aberrations abnormal changes of grade Ⅲ visual function is very ideal Surgical approach.
