Evaluation of anterior capsular contraction syndrome after cataract surgery with commonly used intraocular lenses

Abstract

Purpose: The purpose of this study was to compare the incidence of anterior capsular contraction syndrome (ACCS) in cataract patients after implantation with one of two most commonly used hydrophobic acrylic lenses. Setting: This study included patients from Loma Linda University, Loma Linda, CA, USA. Design: This study is a retrospective chart review. Methods: In this study, 1,047 eyes of 811 patients with and without known ACCS risk factors who underwent successful phacoemulsification and intraocular lens (IOL) implantation were included. Eyes that sustained intraoperative capsular tears and patients with a postoperative follow-up of <1 month were excluded. Each patient underwent surgery by the same surgeon receiving either the SN60WF IOL or the ZCB00 IOL. The duration of postoperative follow-up along with the presence of ACCS and the dimensions of the anterior capsule opening in these cases were recorded. The incidence of ACCS between the two lenses was compared. Results: ACCS was significantly ( P =0.045) less frequent in those patients who received the ZCB00 lens compared to those who received the SN60WF lens, despite a significantly greater ( P <0.0001) number of patients with ACCS risk factors in the ZCB00 cohort. Conclusion: In a direct comparison of the ZCB00 and SN60WF IOLs, a lower incidence of ACCS was found with ZCB00 IOL.
