目的：前瞻性评估糖尿病患者白内障手术后前囊开口收缩与后囊混浊 (PCO) 之间的关系。地点：东京大学医学院眼科、滨松凯亚眼科诊所和日本茨城县筑波大学临床医学研究所眼科。方法：本研究包括 45 名糖尿病患者（45 只眼），白内障手术。术后 1 天和 1 年，使用眼前节分析系统（EAS-100，Niclek，Inc.）通过透光镜检查所有眼睛的前囊开口面积和 PCO 程度。结果：术后 1 天前囊开口面积的大小与术后 1 年的 PCO 程度之间没有相关性（Pearson 相关系数 [r] = 0.041；P = .79）。术后 1 天至 1 年的前囊开口面积缩小百分比与术后 1 年的 PCO 程度不相关 (r = -0.08; P = .60)。结论：白内障手术后前囊开口收缩和 PCO 不能用共同的机制来解释。
Purpose: To prospectively assess the relationship between contraction of the anterior capsule opening and posterior capsule opacification (PCO) after cataract surgery in patients with diabetes mellitus.Setting: Department of Ophthalmology, University of Tokyo School of Medicine, Tokyo, Kaiya Eye Clinic, Hamamatsu, and Department of Ophthalmology, Institute of Clinical Medicine, University of Tsukuba, Ibaragi, Japan.Methods: This study comprised 45 patients (45 eyes) with diabetes mellitus who had cataract surgery. In all eyes, the anterior capsule opening area and degree of PCO were determined by diaphanoscopy using an anterior eye segment analysis system (EAS-100, Niclek, Inc.) 1 day and 1 year postoperatively.Results: There was no correlation between the size of the anterior capsule opening area 1 day after surgery and the degree of PCO 1 year after surgery (Pearson correlation coefficient [r] = 0.041; P = .79). The percentage reduction in the anterior capsule opening area from 1 day to 1 year after surgery did not correlate with the degree of PCO 1 year after surgery (r = -0.08; P = .60).Conclusion: Contraction of the anterior capsule opening and PCO after cataract surgery cannot be explained by a common mechanism.
