RESUMO
PURPOSE: To investigate whether there was any difference in anterior capsular opening area between the use of silicone intraocular lens(IOL) and acrylic IOL after continuous curvilinear capsulorhexis(CCC). METHODS: In 42 eyes, acrylic IOL(Acrysof(R), Alcon, U.S.A.) were inserted into the capsular bag during phacoemulsification, and in 36 eyes silicone IOL(Chiroflex II(R) , Chiron, U.S.A.) were inserted. The reduction rate of anterior capsular opening area at first, second, third and sixth postoperative month were compared between the two groups. RESULTS: On the whole, the reduction in anterior capsular opening area was larger by 0.574 mm 2 when silicone IOL was used, but the different was not statistically significant(P= .061). The result was the same at 1 month(P= .149), 2 months(P= .144), 3 months(P= .223), 6 months(P= .163) after surgery. CONCLUSIONS: We concluded that there was little difference in the changes of anterior capsular opening area after CCC between the use of silicone IOL and acylic IOL, and other factors should be considered.
