目的 比较分析单眼与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 对单眼和双眼人工晶状体手术患者各 6 0例分别检测矫正视力、屈光状态、双眼影像 ,以及用同视机等方法检查双眼视功能。结果 两组患者的双眼同时视功能、融合功能无显著差异。双眼手术组患者的远近立体视功能显著优于单眼组。影响单眼手术患者双眼视功能恢复的主要原因是另侧非手术眼的白内障所导致的视力低下和两眼屈光参差。结论 双眼视功能恢复水平是评价人工晶状体术后视觉质量和生活能力改善的重要指标。单眼手术和双眼手术者双眼视觉的差异主要体现在立体视功能上
Objective To compare the binocular visual function recovery after monocular and binocular senile cataract extraction and intraocular lens implantation. Methods Sixty patients with monocular and binocular IOLs were examined for corrected visual acuity, refractive status, binocular vision, and binocular vision by using the same method. Results The binocular visual function and fusion function of two groups of patients showed no significant difference. The binocular surgery group had far superior stereopsis better than monocular group. Affect binocular surgery patients with binocular visual function recovery is mainly due to the other side of the non-surgical eye cataract caused by poor vision and refractive anisometropia. Conclusions The recovery of binocular vision is an important index to evaluate the improvement of visual quality and viability after intraocular lens implantation. Monocular surgery and binocular surgery binocular vision differences are mainly reflected in the stereopsis function
