Purpose: To evaluate the safety and the optical quality of aspheric intraocular lens (IOLs) RAY-61PL.

Methods: One hundred and twenty two eyes who had phacoemulsification in a randomized prospective single masked clinical trial recieved a RAY-61PL (61 eyes) (study group) or RF-31PL (61eyes) (control group). The rate of endothelial cell loss (ECL) and the rate of change in central corneal thickness (CCT) and anterior chamber flare (ACF) count were compared between groups as safety parameters. The optical quality was assessed and compared between groups in term of total spherical aberration.

Results: The rate of ECL from preoperatively to 21 days postoperatively was 224.67 ± 213.94 in RAY-61PL group and 227.18 ± 189.96 in RF-31PL group (p>.05). There was no statistically significant difference in the rate of change in CCT and ACF count between groups from preoperatively to 21 days postoperatively, -4.44 ± 26.15 versus -5.88 ± 33.95 and 0.25 ± 4.82 versus 0.26 ± 4.03, respectively (both p>.05). The mean of total spherical aberration at 21 days postoperatively was not different statistically in any groups at any pupil diameters (p>.05).

Conclusions: Aspheric IOLs RAY-61PL and spherical IOLs RF-31PL were comparable for safety and optical quality, but aspheric IOLs RAY-61PL showed better total spherical aberration value in mesopic pupils.
