To understand whether the binocular visual function could be restored after posterior chamber intraocular lens (IOL) implantation.
The visual function including corrected vision, simultaneous perception, fusion, stereoacuity, aniseikonia and retinal correspondence point were determined for 50 cases (64 eyes) after the surgery.
The corrected visual acuities were 0.6 or better. Visual acuities of 1.0 or better were achieved in 65% and 0.6-0.9 in 35% of the eyes. All patients obtained simultaneous perception and fusion function. The near stereoacuity of 50 cases showed foveal stereoacuity < or = 60 seconds in 23 cases (46%), macular stereoacuity 80-200 seconds 10 cases (20%) and peripheral stereoacuity 400 seconds 17 cases (34%). The far stereoacuity of 50 cases comprised 34 cases of foveal stereoacuity (68%), 9 cases of macular stereoacuity (18%) and 7 cases of peripheral stereoacuity (14%). The postoperative retinal correspondence points were normal. There was no aniseikonia in 35 cases, except 15 cases of aniseikonia which was within normal tolerable limits.
When binocular corrected vision is > or = 0.4 with ocular alignment, the binocular visual function could be restored for varying degrees.
了解后房型人工晶状体植入术后双眼视觉功能能否恢复。
对50例（64只眼）手术后患者的视觉功能进行测定，包括矫正视力、同时视、融合功能、立体视锐度、像不等及视网膜对应点。
矫正视力均在0.6及以上。65%的眼视力达到1.0及以上，35%的眼视力在0.6 - 0.9。所有患者均获得同时视和融合功能。50例患者近立体视锐度中，23例（46%）黄斑中心凹立体视锐度≤60秒，10例（20%）黄斑立体视锐度80 - 200秒，17例（34%）周边立体视锐度400秒。50例患者远立体视锐度中，34例（68%）为黄斑中心凹立体视锐度，9例（18%）为黄斑立体视锐度，7例（14%）为周边立体视锐度。术后视网膜对应点正常。35例无像不等，15例有像不等，但在正常耐受范围内。
当双眼矫正视力≥0.4且眼位正位时，双眼视觉功能可不同程度恢复。
