Abstract
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.
