To evaluate whether cognitive impairment improves in elderly patients who have cataract surgery with intraocular lens (IOL) implantation.
Kouki Hospital, Yamaguchi, Japan.
A prospective observational study evaluated patients' scores on the Revised Hasegawa Dementia Scale (HDS-R) and the HDS-R minus 1 item regarding immediate regeneration (ie, function of vision and memory). Twenty patients (6 men, 14 women) with cognitive impairment had cataract surgery in 1 eye between March 1996 and July 2001 at Kouki Hospital, Japan. The mean age of the patients was 81.8 years (range 61 to 90 years). Twenty patients (4 men, 16 women) with cognitive impairment who did not have cataract surgery were selected as a control. The mean age in the control group was 84.3 years (range 70 to 93 years). The HDS-R was administered twice between March 1996 and July 2001.
The mean HDS-R scores in the cataract surgery group improved from 12.5 points +/- 5.3 (SD) preoperatively to 16.6 +/- 6.2 points postoperatively; the improvement was significant (t = -5.02; P<.0001). After cataract surgery, the grade of cognitive impairment improved in 12 patients (60%), was unchanged in 7 (35%), and was worse in 1 (5%).

评估行白内障手术并植入人工晶状体（IOL）的老年患者认知功能障碍是否有所改善。
日本山口县光喜医院。
一项前瞻性观察性研究评估了患者在修订版长谷川痴呆量表（HDS-R）以及减去一项关于即刻恢复（即视力和记忆功能）的HDS-R上的得分。1996年3月至2001年7月期间，20例认知功能障碍患者（6例男性，14例女性）在日本光喜医院接受了单眼白内障手术。患者的平均年龄为81.8岁（范围61至90岁）。选取20例未接受白内障手术的认知功能障碍患者（4例男性，16例女性）作为对照。对照组的平均年龄为8�.3岁（范围70至93岁）。1996年3月至2001年7月期间对HDS-R进行了两次测量。
白内障手术组的HDS-R平均得分从术前的12.5分±5.3（标准差）提高到术后的16.6±6.2分；改善具有显著性（t = -5.02；P<.0001）。白内障手术后，12例患者（60%）的认知功能障碍等级有所改善，7例（35%）无变化，1例（5%）恶化。
