Clinical Results of Centerflex(R) Intraocular Ocular Lenses and Acrysof(R) Intraocular Ocular Lenses in Bilateral Cataracts

ABSTRACT

PURPOSE: To compare the clinical results of hydrophilic acrylic IOL 570H (Centerflex(R), Rayner, UK) with those of hydrophobic acrylic IOL MA60BM (Acrysof(R), Alcon, USA). METHODS: Centerflex(R) and Acrysof(R) were each implanted in one eye of 31 patients with bilateral cataracts. We evaluated and compared best corrected visual acuity (BCVA, logMAR), refractive error, anterior capsular fibrosis, and posterior capsular opacification at mean 9.3 months after surgery. RESULTS: BCVA (logMAR) was 0.04 +/- 0.07 in the Centerflex(R) group and 0.03 +/- 0.07 in the Acrysof(R) group. There was no statistically significant difference between the two groups. Refractive error was -0.23 +/- 0.76 diopter (D) in the Centerflex(R) group and 0.09 +/- 0.61 D in the Acrysof(R) group. There was a statistically significant difference of refractive error between the two groups (p=0.02). In the Centerflex(R) group, the rates of both anterior capsular fibrosis and posterior capsular opacification were statistically significantly higher than those in the Acrysof(R) group (both, p=0.05). CONCLUSIONS: We found no statistically significant difference of postoperative visual acuity between Centerflex(R) and Acrysof(R) lenses implanted in the bag after phacoemulsification. However, mean refractive error in eyes implanted with Centerflex(R) lens was -0.23 D at mean 9.3 months after surgery and we recommended that the preoperative target refraction of the Centerflex(R) lens be 0.23 D hyperopic and that postoperative anterior capsular fibrosis and posterior capsular opacification be checked carefully.
