摘要
目的 :了解双眼行白内障人工晶状体植入术后患者的双眼视功能恢复情况并探讨影响其恢复的因素。方法 :对80例 (16 0只眼 )老年性白内障患者双眼均采用Phaco或小切口ECCE后房型人工晶状体植入术。术后检查矫正视力、同时视觉、融合功能及远、近距离立体视功能以及视网膜对应情况。结果 :术后患者双眼矫正视力均≥ 0 3,其中矫正视力均≥ 0 5者76例 (95 % ) ,矫正视力均≥ 0 9者 6 0例 (75 % )。术后均有同时视功能及一定的融合功能。近距离立体视检查 :中心凹立体视(4 0″～ 6 0″) 32例 (占 4 0 % ) ,黄斑部立体视 (80″～ 2 0 0″) 30例 (占 37 5 % ) ,周边部立体视 (4 0 0″～ 80 0″) 15例 (占 18 8% ) ,无立体视者 3例 (占 3 7% )。远距离立体视中 :中心凹立体视者 6 5例 (81 3% ) ,黄斑部立体视者 12例 (占 15 % ) ,周边部立体视者 3例 (占 3 7% )。术后视网膜对应均正常。结论 :双眼白内障摘除人工晶状体植入手术且双眼矫正视力均≥ 0 5者 。
Objective:To study the recovery of binocular visual function and the factors that affect the recovery of binocular visual function after bilateral cataract surgery.Methods:80 cases (160 eyes),who had bilateral cataract sugery of Phaco or small incision (ECCE) with posterior chamber IOL implantation (the other eye was operated one week later),were examined for their corrected vision,simultaneous perception,fusion,near and far distance stereoacuity and retinal correspondence point.Results:The corrected visual acuities were 0.3 or better in all eyes.In 95% of the eyes the vision reached≥0.5,and in 75% reached≥0.9.All patients obtained simultaneous perception and fusion function.Of 80 cases,32 cases (40%) had foveal stereoacuity (40″～60″),30 cases (37.5%) had macular stereoacuity(80″～200″) and 15 cases (18.8%) had peripheral stereoacuity(400″～800″) in the near-stereoacuity respectively,and 3 cases(3.8%) had no stereoacuity.65 cases (81.3%),12 cases(15%) and 3 cases (3.7%) had far-stereoacuity respectively.All the postoperative retinal correspondence points were normal.Conclusion:When bilateral cataract surgery with binocular corrected visual acuity≥0.5 after ocular alignment,the binocular visual function could be restored for varying degrees.
