摘要
目的探讨双眼老年性白内障摘除人工晶状体植入术后双眼视功能恢复状况。方法双眼人工晶状体植入患者和与之年龄匹配的健康对照组各60例,年龄60～79岁。双眼视力或矫正视力均≥0.8。分别检测双眼屈光状态、影像不等,融合功能以及远、近立体视功能。结果 (1)双眼影像不等同时视像差在0%～3%者,白内障手术组48例,对照组54例,两组平均像差差异无统汁学意义(P>0.05);(2)融合范围白内障手术组平均为(25.6±8.7)度,正常对照组平均为(27.8±6.7)度。两组的融合范围比较差异无统计学意义(P>0.05)。(3)白内障手术组与对照组分别有85.0%和91.7%被检者获得不同程度的远距离立体视,分别有75.0%和80.0%被检者获得不同程度的黄斑中心近距离立体视(均为 P>0.05)。结论双眼人工晶状体植入术可恢复患者双眼视功能,使之达到满意的视功能状态。
Objective To investigate binocular function after bilateral implantation of intraocular lens（IOL）. Methods Sixty patients who underwent bilateral phacoemulsification with IOL implantation and 60 age-matched healthy person were involved in this reseach. The age ranged 60-79 yeaes. Visual acuity or corrected vision all were over 0.8 in both eyes. The refractive state, aniseikonia, fusion, binocular image,near and distant stereoscopic vision in 120 cases （240 eyes） were observed. Results （1）There were 48 person in operation group and 54 person in control group who reached the aniseikonia of 0%-3% （t= 1.16,P〉0.05）. （2） The average fusion range was 25.6°± 8. 7° in operation group and 27.8°±6.7° in control group respectively（t= 1.74,P〉0.05）. （3）There was more or less far distance stereoacuity in 85.0% of operation group and in 91.7% of control group, no statistical significance was observed （X^2 =0. 73, P 〉 0. 05）. Foveal near stereoacuity was established in operation group （75.0 %） and in control group （80. 0 % ） with no statistical significance （x^2 =0. 19,P〉0. 05）. Conclusions Bilateral implantation of IOL provides good binocular function.
