The Rate of Posterior Capsular Opacification with Three Different Sizes of Capsular Intraocular Lenses

ABSTRACT

A prospective study was carried out in 124 cataract patients(140 eyes) to evaluate the rate and degree of the opacification and/or wrinkling of the posterior capsule after in-the-bag placement of 6 mm optic capsular IOLs-12.0mm, 12.5mm and 13.0mm loop to loop total length were inserted. Cases only with intact CCC(continuous curvilinear capsulorhexis) and in-the-bag placement of PCLs (posterior chamber lenses) were included but any case of operative complications were not included. The rate and degree of opacification and/or wrinkling of the opsterior capsule were observed at 1 week, 1 month, 2 months, 3 months, 6 months, and 12 months after operation, respectively. Posterior capsular wrinkling with striae increased with total length of capsular IOL up to postoperative 1 month but thereafter there were no significant differences among the three different sizes of I0Ls througthout the follow up periods. The differences of rate and degree of posterior capsular opacification among IOLs were not statistically significant during the follow up periods. Mild degree of IOL decentration -0.5mm to 1.0mm pccired in 10 eyes(7%). Nd/Yag laser posterior capsulotomy was done in 3 eyes(2%).
