Zusammenfassung: <jats:sec><jats:title>Purpose</jats:title><jats:p>Evaluation of capsulorhexis contraction in two different shapes of hydrophobic acrylic intraocular lenses (IOLs).</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>The study was conducted on 69 eyes that had undergone cataract surgery. FY‐60AD (HOYA) or ZCB00V (AMO) were randomly selected and implanted after phacoemulsification. The FY‐60AD has usual shapes of optics; however, the ZCB00V has rim at peripheral of optics. Anterior retro illumination images were photographed using slit lamp and EAS1000 (NIDEK) at 1 weeks, 1 month, 3 months and 6 months postoperatively. Capsulorhexis opening area were analyzed and the reduction ratios of capsulorhexis area were compared. After that, fibrosis in anterior capsule were also measured using area analysis software (Area Q, S‐Tech) after 3 months postoperatively.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Reduction rate of capsulorhexis opening area were 5.44 ± 10.15% (FY‐60AD) and 0.25 ± 2.36 μ (ZCB00V) after 6 months postoperatively. There were statistically significance (P &lt; 0.01). The area of fibrosis in anterior capsule were 62.24 ± 21.32% (FY‐60AD) and 16.90 ± 8.34% (ZCB00V). There were statistically significance, too (P &lt; 0.01).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>The ZCB00V prevent the contraction of capsulorhexis opening area. And the increase of fibrosis is also prevented at the same time. The shape of optics may be an important factor to prevent the contraction of capsulorhexis.</jats:p></jats:sec>
