Abstract
Purpose:
To investigate the efficacy of large size capsulorrhexis and intraocular lens (IOL) to obtain the larger area of anterior capsular opening (ACO) after cataract surgery in the patients with diabetes mellitus.
Methods:
This study was conducted as prospective comparative study. Cataract surgery with 2.8- and 3.0-mm scleral incision, approximately 5- and 6-mm diameter capsulorrhexis and the implantation of 6- and 7- mm diameter IOL, respectively were performed in the one and the fellow eye of each patient diagnosed with diabetes mellitus. The ACO areas, aqueous flare intensity, surgically induced astigmatism, corneal endothelial cell density and corneal thickness were measured at 1 day, 1 week, 1, 3 and 6 months after surgery.
Results:
Thirty-one patients with diabetes mellitus were enrolled. The area of ACO after cataract surgery was significantly larger in the eyes implanted with 7- mm diameter IOL compared to those with 6- mm diameter IOL at any time point postoperatively (P < 0.05, Mann-Whitney’s U test). There were no significant differences between both groups before and after surgery in the aqueous flare intensity, the surgically induced astigmatism, the corneal endothelial cell density or central corneal thickness.
Conclusions:
Based on our results, a creation of larger capsulorrhexis and the implantation of 7- mm IOL result in the greater opening area, and thus this technique may be recommended in cataract surgery for the patients with diabetes mellitus.
