The analysis of predicted capsular bag diameter using modified model of capsule measuring ring in Asians

Background:  This study measured the capsular bag diameter (CBD) of Asian eyes using a modified capsular measuring ring (CMR) after cataract surgery, and identified preoperative predictive factors for postoperative CBD and the change of capsular bag diameter after surgery. Methods:  This prospective...

Description
Summary:Background:  This study measured the capsular bag diameter (CBD) of Asian eyes using a modified capsular measuring ring (CMR) after cataract surgery, and identified preoperative predictive factors for postoperative CBD and the change of capsular bag diameter after surgery. Methods:  This prospective study followed 25 eyes undergoing cataract surgery inserted with a CMR before intraocular lens (IOL) implantation at the Department of Ophthalmology, Ilsan Paik Hospital, Inje University, Republic of Korea. Axial length (AL), anterior chamber depth (ACD), lens thickness, corneal power and corneal size were measured preoperatively. CBD was calculated using the CMR in a dilated state at postoperative 1 day, 1 week, 1 month, 2 months, and 1 year. Results:  AL (R = 0.713) and ACD (R = 0.402) were found to positively correlate with CBD at postoperative 1 week. AL (P
