We evaluated the contraction of anterior capsulotomy opening as related to its initial size in 90 eyes following curvilinear capsulorrhexis, phacoemulsification- aspiration and in-the-bag fixated intraocular lens implantation. We used 3 types of intraocular lens (JUL) : 5.5 mm PMMA IOL, 6.0 mm acrylic IOL and 6.0 mm silicone IOL. The area of anterior capsular opening decreased following surgery. When compared with the size one week after surgery, the rate of decrease 3 years later was 15.1% for PMMA IOL which was significantly greater than 4.1% for acrylic IOL and 7.9% for silicone IOL (p < 0.05) . In eyes with capsular opening larger than 6.0 mm (28.3 mm3) , the rate of decrease was 18.4% for PMMA IOL which was greater than 3.4% for acrylic IOL and 4.4% for silicone IOL (p <0.01) . In eyes with capsular opening smaller than 6.0 mm, there was no difference in the rate of decrease among the 3 IOLs. Contraction of anterior capsulotomy opening was less when the edge of capsulotomy lay on the IOL optics. We advocate capsulotomy with 5.5mm opening in order to prevent postopera-tive contraction.
