To evaluate the efficacy of a large capsulorhexis and intraocular lens (IOL) in obtaining a larger anterior capsule opening after cataract surgery in patients with diabetes mellitus (DM).
Department of Ophthalmology, University of Fukui, Fukui, Japan.
Prospective clinical trial.
Patients with DM had bilateral cataract surgery with a 2.8 or 3.0 mm scleral incision, a capsulorhexis with a diameter of approximately 5.0 or 6.0 mm, and implantation of a 6.0 mm optic (Eternity X-60) or 7.0 mm optic (Eternity X-70) IOL. The anterior capsule opening area, aqueous flare intensity, surgically induced astigmatism (SIA), corneal endothelial cell density (ECD), and central corneal thickness (CCT) were measured 1 day, 1 week, and 1, 3, and 6 months after surgery.
Thirty-one patients (62 eyes) with DM were enrolled. At all postoperative timepoints, the anterior capsule opening was significantly larger in eyes with the 7.0 mm optic IOL than in eyes with the 6.0 mm optic IOL (P<.05, Mann-Whitney U test). There were no significant differences in postoperative aqueous flare intensity, SIA, ECD, or CCT based on the size of the capsulorhexis and IOL.
A larger capsulorhexis and implantation of a 7.0 mm IOL resulted in a larger anterior capsule opening after cataract surgery in patients with DM.

评估在糖尿病（DM）患者白内障手术后，大直径连续环形撕囊术和人工晶状体（IOL）在获得更大前囊开口方面的疗效。

前瞻性临床试验。
糖尿病患者接受双侧白内障手术，采用2.8或3.0mm巩膜切口、直径约5.0或6.0mm的连续环形撕囊术，并植入6.0mm光学部（Eternity X - 60）或7.0mm光学部（Eternity X - 70）的人工晶状体。在术后1天、1周以及1、3和6个月测量前囊开口面积、房水闪光强度、手术源性散光（SIA）、角膜内皮细胞密度（ECD）和中央角膜厚度（CCT）。
纳入31例（62只眼）糖尿病患者。在所有术后时间点，7.0mm光学部人工晶状体眼的前囊开口明显大于6.0mm光学部人工晶状体眼（P<0.05，Mann - Whitney U检验）。基于连续环形撕囊术和人工晶状体的大小，术后房水闪光强度、手术源性散光、角膜内皮细胞密度或中央角膜厚度无显著差异。
对于糖尿病患者，更大直径的连续环形撕囊术和植入7.0mm人工晶状体可使白内障手术后的前囊开口更大。
