영문 초록

Purpose: This study evaluates the capsular bag diameter (CBD) with a capsular tension ring (CTR) following cataract surgery and analyzes the predictive factors correlated with capsular bag size to predict CBD preoperatively. Methods: We inserted the CTR before intraocular lens (IOLs) implantation in 25 eyes undergoing cataract surgery. The axial length (AL), anterior chamber depth (ACD), and lens thickness were measured and keratometry and corneal size were checked preoperatively. Also, the continuous curvilinear capsulorhexis size was measured at 7 days postoperative, and CBD was calculated with CTR in a dilated state at 1day, 1week, 1 month, and 2 months postoperative. Results: The mean CBD gradually decreased from 11.30±1.76 mm at 1 day, 10.86±1.06 mm at 1 week, 10.23±1.43 mm at 1 month, and 9.88±1.31 mm at 2 months. The AL (R=0.657), ACD (R=0.481), and corneal size (R=0.348) had a positive correlation with CBD at 1 week postoperative. The AL (P=0.000) and ACD (p=0.015) were statistically significant predictive factors for CBD. Conclusions: Calculating CBD with the CTR helps to improve visual acuity following cataract surgery after implantation of IOLs having appropriate sizes predicted with AL, ACD, and corneal size.
