To analyze changes in visual acuity after cataract surgery in patients suffering from age-related maculopathy.
This retrospective case-control study included all patients who had consecutively undergone phacoemulsification from January 2000 to February 2006, had a preexisting diagnosis of early age-related macular degeneration (AMD), and were followed up for at least 1 year postoperatively (n=1,152 eyes of 696 patients). The control group comprised phakic patients diagnosed with early AMD from January 2000 to February 2006 who did not undergo eye surgery and were followed up for at least 1 year (n=334 eyes of 202 patients).
In 62.1% of operated eyes, the best-corrected visual acuity was at least two logMAR units better than before surgery, and in 26.7% it was at least four logMAR units better. Deterioration of visual acuity of more than four logMAR units occurred in 1.3% of operated eyes and 1.5% of control eyes.
Cataract surgery can markedly improve visual acuity in patients with age-related maculopathy.
分析年龄相关性黄斑病变患者白内障手术后视力的变化。
这项回顾性病例对照研究纳入了2000年1月至2006年2月期间连续接受超声乳化白内障吸除术、术前已诊断为早期年龄相关性黄斑变性（AMD）且术后至少随访1年的所有患者（696例患者的1152只眼）。对照组包括2000年1月至2006年2月期间诊断为早期AMD但未接受眼部手术且至少随访1年的有晶状体眼患者（202例患者的334只眼）。
在62.1%的手术眼中，最佳矫正视力比手术前至少提高了两个最小分辨角对数（logMAR）单位，在26.7%的手术眼中至少提高了四个logMAR单位。手术眼和对照眼中视力下降超过四个logMAR单位的分别占1.3%和1.5%。
白内障手术可显著提高年龄相关性黄斑病变患者的视力。
