To compare the visual function among 3 aspheric intraocular lenses (IOLs) after cataract surgery.

A prospective analysis among 70 eyes of 68 patients who had undergone phacoemulsification and implantation of aspheric IOLs (Acrysof IQ, 30 eyes; Tecnis ZA9003, 20 eyes; Akreos Adapt-AO, 20 eyes) was performed. The best corrected visual acuity (BCVA), refraction, coma, trefoil, spherical aberration, root-mean-square (RMS), contrast sensitivity test, satisfaction and glare was evaluated during the follow-up period of 3 months.

There were no significant differences in BCVA, satisfaction, glare, coma, trefoil, RMS and contrast sensitivity test among the 3 aspheric IOLs. Spherical aberration in Akreos Adapt-AO (0.04±0.05 µm) was higher compared with Acrysof IQ (0.03±0.04 µm) and Tecnis ZA9003 (0.11±0.03 µm)( p <0.01). The predictability of postoperative spherical equivalent in the Akreos Adapt-AO group (-0.57±0.22D) represented a statistically significant myopic refractive error compared with the Acrysof IQ (0.01±0.77D) and the Tecnis ZA9003 (-0.20±0.71D) groups ( p =0.04).

There were no significant differences in visual function except spherical aberration, which was highest in the Akreos Adapt-AO group.
