Problems in daily life activities caused by bad vision were studied in 150 patients with cataract before and 6 months after a cataract extraction. A relation was found between binocular visual acuity before surgery and the number of problems experienced (p < 0.001). After cataract extraction a reduction in problems was closely associated with an increase in visual acuity (p < 0.001) and also, in the patients' opinion, a better life situation (p < 0.001). Six questions to be answered when considering surgery are given.
对150例白内障患者在白内障摘除术前及术后6个月时日常生活活动中因视力不佳所导致的问题进行了研究。发现术前双眼视力与所经历问题的数量之间存在关联(p<0.001)。白内障摘除术后,问题的减少与视力的提高密切相关(p<0.001),并且在患者看来,生活状况也有所改善(p<0.001)。文中给出了在考虑手术时需要回答的六个问题。
