To determine whether there is a need for second eye cataract surgery or whether cataract surgery in one eye provides sufficiently adequate vision.
The vision of 43 patients was assessed using a battery of clinical vision tests, performance-based functional vision tests, and quality of life questionnaires, both before and a few months after cataract surgery. Twenty-five patients underwent second eye surgery and 18 patients underwent first-eye surgery. To determine whether cataract surgery returned vision to normal levels, a control group of 25 subjects of a similar age with normal, healthy eyes was also assessed.
Overall, greater improvements occurred in most aspects of vision after first eye surgery than after second eye surgery. However, second eye surgery provided similar improvements in mobility orientation and self-reported night driving to those after first eye surgery, and substantially greater improvements in stereoacuity and reductions in anisometropia.
The study provides additional evidence to support the need for second eye cataract surgery. Second eye surgery may be particularly important to improve mobility orientation and the avoidance of falls.
确定是否需要进行另一只眼的白内障手术，或者一只眼的白内障手术是否能提供足够良好的视力。
在白内障手术前及术后几个月，使用一系列临床视力测试、基于表现的功能性视力测试和生活质量问卷对43例患者的视力进行评估。25例患者接受了另一只眼的手术，18例患者接受了第一只眼的手术。为了确定白内障手术是否能使视力恢复到正常水平，还对25名年龄相仿、眼睛正常健康的受试者组成的对照组进行了评估。
总体而言，第一只眼手术后视力的大多数方面的改善比第二只眼手术后更大。然而，第二只眼手术在移动定向和自我报告的夜间驾驶方面提供了与第一只眼手术后相似的改善，并且在立体视锐度方面有显著更大的改善，屈光参差也有所降低。
该研究提供了额外的证据支持进行另一只眼白内障手术的必要性。第二只眼手术对于改善移动定向和避免跌倒可能尤为重要。
