Spherical aberration, visual performance and pseudoaccommodation of eyes implanted with different aspheric intraocular lens

Purpose: To compare spherical aberration, visual performance and pseudoaccommodation in pseudophakic eyes implanted with aspheric intraocular lenses (IOLs) of Tecnis Z9001 with negative spherical aberration (AMO Inc.), aspheric aberration‐free IOLs of Akreos AO (Bausch & Lomb Inc.) and spherical IOLs of KS‐1 (Cannon Staar Inc.). Methods: A total of 196 patients presenting for cataract surgery were randomly assigned to receive one of three types of IOLs in one eye. Spherical aberration, best‐corrected far visual acuity (BCFVA), distance corrected near visual acuity (DCNVA), contrast sensitivity, glare sensitivity and pseudoaccommodation were measured and compared 3 months postoperatively. Results: At 3 months postoperatively, the mean spherical aberration Z(4,0) for 5 mm pupil size in eyes with Tecnis Z9001 IOLs, Akreos AO IOLs, and KS‐1 IOLs were 0.022 ± 0.071 µm, 0.141 ± 0.070 µm and 0.210 ± 0.108 µm, respectively (P
