| 摘要 目的：了解双眼行白内障人工晶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（160只眼）老年性白内障患者行双眼手术（对侧眼间隔一周后手术），双眼均采用Phaco或小切口ECCE后房型人工晶体植入术。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：术后患者矫正视力均≥0.3，其中矫正视力均≥0.5(分别双眼)的患者76例（95%），矫正视力均≥0.9(分别双眼)的患者60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（40"~60"）32例（占40%），黄斑部立体视（80"~200"）30例（占37.5%），周边部立体视（400"~800"）15例（占18.8%），无立体视者3例(占3.8%)。远距离立体视中：中心凹立体视者65例（81.3%），黄斑部立体视者12例（占15%），周边部立体视者3例（占3.8%）。术后视网膜对应均正常。结论：双眼行白内障人工晶体植入手术且双眼矫正视力分别≥0.5者，均可以尽早恢复一定程度的双眼视功能。

Abstract 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) undergone bilateral cataract sugery of Phaco or small incision ECCE with posterior chamber IOL implantation (another eye was operated after a week), 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, Visual acuities ≥0.5 were reached in 95% and ≥0.9 in 75% of the eyes. All patients obtained simultaneous perception and fusion function. Foveal stereoacuity(40"~60"), macular stereoacuity (80"~200") and peripheral stereoacuity (400"~800") in the near-stereoacuity respectively were 32 cases (40%), 30cases (37.5%) and 15 cases (18.8%) of 80 cases and 3 cases (3.8%) was no stereoacuity. That in the far-stereoacuity respectively were 65 cases (81.3%), 12cases (15%) and 3 cases (3.8%). The postoperative retinal correspondence points all were normal. Conclusion When bilateral cataract surgery and binocular corrected visual acuity is ≥0.5 with ocular alignment, the binocular visual function could be restored for varying degrees.
