Abstract:
PURPOSE:To compare the visual function among 3 aspheric intraocular lenses (IOLs) after cataract surgery. METHODS: 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. RESULTS: 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 microm) was higher compared with Acrysof IQ (0.03+/-0.04 microm) and Tecnis ZA9003 (0.11+/-0.03 microm)(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). CONCLUSIONS: There were no significant differences in visual function except spherical aberration, which was highest in the Akreos Adapt-AO group.
