To investigate the effect of cataract surgery on visual acuity, stereoacuity, balance, and falls in patients with senile cataract.
Prospective, cross-sectional study. The patients were divided into group 1 if the first surgery was performed on the dominant eye and group 2 on the nondominant eye. After a complete ophthalmologic examination, all patients underwent stereoacuity tests (Titmus and TNO test); Berg Balance Scale and the number of falls in the last 36 months were recorded. All assessments were performed at three time points: the preoperative period, 6 months after the first surgery (primary endpoint), and 24 months after the second surgery (secondary endpoint).
The mean number of falls was 4.95±2.6/year in the preoperative period and 1.43±0.59/year in the postoperative period. The incidence of falls after the second surgery decreased by 53.15% compared with the preoperative period. The number of falls and preoperative stereoacuity were negatively and moderately correlated (r=-0.546) ( P =0.033). In univariate and multivariate analysis, only low preoperative corrected distance visual acuity in the dominant eye was associated with poor stereoacuity ( P =0.001) and a high number of falls ( P <0.001) in the preoperative period.
Cataract surgery in patients with senile cataracts not only improves visual acuity but also increases stereoacuity level, improves balance, and decreases falls. These effects should be further studied in multicenter, large-participant studies.
探讨白内障手术对老年性白内障患者视力、立体视锐度、平衡能力及跌倒情况的影响。
前瞻性横断面研究。若首次手术在优势眼进行，则将患者分为第1组；若在非优势眼进行，则分为第2组。在进行全面的眼科检查后，所有患者均接受立体视锐度测试（Titmus和TNO测试）；记录Berg平衡量表及过去36个月内的跌倒次数。所有评估均在三个时间点进行：术前、首次手术后6个月（主要终点）和第二次手术后24个月（次要终点）。
术前平均跌倒次数为4.95±2.6次/年，术后为1.43±0.59次/年。第二次手术后跌倒发生率较术前降低了53.15%。跌倒次数与术前立体视锐度呈负相关且具有中度相关性（r=-0.546）（P=0.033）。在单因素和多因素分析中，仅术前优势眼的低矫正远视力与术前较差的立体视锐度（P=0.001）及高跌倒次数（P<0.001）相关。
老年性白内障患者的白内障手术不仅能提高视力，还能提高立体视锐度水平、改善平衡能力并减少跌倒。这些效果应在多中心、大样本研究中进一步探讨。
