Abstract Details

Purpose:

Evaluation of capsulorhexis contraction postoperatively in two different hydrophobic acrylic intraocular lenses (IOLs) having peripheral grooves.

Setting:

Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Methods:

The study was conducted on 47 eyes that had undergone cataract surgery. ZCB00V (AMO) or SZ-1 (NIDEK) were randomly selected and implanted after phacoemulsification. Anterior retro illumination images were photographed using slit lamp and EAS1000 (NIDEK) at 1 weeks, 1 month and 3 months postoperatively. Capsulorhexis opening area were analyzed and the ratios of area were compared. After that, fibrosis of anterior capsule were also measured using area analysis software (Area Q, S-Tech) after 3 months postoperatively. Unpaired t-test was used for statistically analysis.

Results:

Reduction rate of capsulorhexis opening area were 1.03±2.54％ (ZCB00V) and 4.23±6.19% (SZ-1) after 3 months postoperatively. The area of fibrosis in anterior capsule were 16.9±8.3% (ZCB00V) and 13.6±11.1% (SZ-1).

Conclusions:

The reduction rate of capsulorhexis opening area were insufficient after implanting ZCB00V and SZ-1. Peripheral optics grooves on IOLs may prevent capsulorhexis contraction.
