Twenty-five patients had bilateral cataract extractions: one eye with peripheral iridectomy and the fellow eye with sector iridectomy. They were followed from four months to two years. No significant differences in visual acuity between the two eyes were found. No patient reported any subjective difference between the right or left eye.
25例患者接受了双侧白内障摘除术：一只眼行周边虹膜切除术，另一只眼行扇形虹膜切除术。对他们进行了4个月至2年的随访。发现两眼之间的视力无显著差异。没有患者报告右眼和左眼之间有任何主观差异。
