Previous study shows the increase of light scatter on the surface of MA60BM (Alcon) intraocular lenses (IOLs). In this study, we evaluate light scatter on surface and center of different types of hydrophobic acrylic IOLs.
The study was conduct 61 eyes of 61 patients that had undergone cataract surgery in Dokkyo Medical University Hospital. SA60AT (Alcon), VA-60BB (HOYA) and ZA9003 (AMO) were randomly selected and implanted after phacoemulsification. The patients had a mean age of 72.5±8.5 years, no history of systemic or ocular complications, and all underwent a complete CCC with IOL fixation in the capsular bag. At 1 week, 6 months and 1 year after surgery, the light scatter on surface of IOLs were measured using an anterior segment analysis system (EAS-1000, Nidek). The images were photographed from 2 directions (0 and 90 degree) and the densities on center and surface of IOLs were measured and compared. The data were analyzed by multiple comparisons using Fisher’s protected least significant difference (PLSD) test, with the level of significance established at P < 0.05.
The table shows the results. In SA60AT, light scatter was significantly increased on surface of IOL. In VA-60BB, light scatter was increased both on surface and center of IOL. In ZA9003, subtle increases were recognized both on surface and center of IOL.
