Capsule contraction syndrome in eight cases of hydrophobic one‐piece intraocular lens implantation

Purpose: The combination of anterior capsule opacification (ACO) with capsulorrhexis phimosis and intraocular lens (IOL) decentration characterises the capsule contraction syndrome (CCS). Eight cases of ACO complicated with capsule phimosis are described. Methods: In this study, 231 patients who underwent cataract extraction using phacoemulsification from September 2005 to May 2006 were included. An acrylic one‐piece IOL was implanted with the use of the injector supplied by the manufacturer through a 2.75 mm incision. A thorough pre‐ and post‐operative examination (visual acuity measurement, corneal curvature measurement, applanation tonometry, fundus examination) was performed for each patient. Results: In eight of 243 eyes of 231 patients, anterior capsule opacification with capsulorrhexis phimosis and IOL decentration was observed two to four months post‐operatively. In all eight cases, the haptic implanted inferiorly was observed to be mounted on the IOL optic. Conclusions: The combination of IOL memory loss in addition to ACO, capsulorrhexis phimosis and decentration can be a cause of the CCS, an observation that has not been reported previously.
