We evaluated the risk factors for anterior capsu-lar shrinkage in 500 eyes after intraocular lens implantation. All the eyes underwent phacoemul-sification/aspiration after continuous circular cap-sulorhexis of about 5mm in diameter. We used posterior chamber lens of 6 or 6.5mm and em-ployed in-the-bag fixation technique. Anterior cap-sular shrinkage was judged as present when the anterior capsular edge was visible in the pupillaryarea by slitlamp examination without myadriatics.

Anterior capsular shrinkage was present in 13 eyes, 2.6%. There was a high incidence of shrinkage in eyes with uveitis or pigmentary retinal dystro-phy. Severe systemic vascular disorders, including myocardial infarction, brain infarction and hyper-cholesteremia, were another contribution factor for shrinkage. The age of cases who developed shrink-age averaged 76.2±8.0 years, which was significant-ly higher than 67.9±11.9 years for those who failed to develop shrinkage. The size and type of intraocu-lar lens did not affect the incidence of shrinkage.
