Abstract

 Purpose: To compare Tecnis Z9000 and Acrysof IQ aspheric intraocular lenses (IOLs) regarding spherical aberration and contrast sensitivity.Methods: Thirty-four eyes of 34 patients undergoing phacoemulsification cataract surgery were randomly assigned to implantation of Tecms or IQ IOLs. Three months postoperatively, best-corrected visual acuity (BCVA), spherical aberration (with 4 and 6 mm pupil diameters) and contrast sensitivity in 'photopic and mesopic conditions at spatial frequencies of 1, 2, 5, 10 and 20 cycles per degree (cpd) were determined.Results: Mean BCVA was 0.083±0.071 logMAR in the IQ group and 0.076±0.080 logMAR in the Tecnis group (P=0.338). Spherical aberration in the Tecnis group was smaller with pupil diameter of 4 mm (0.140±0.097pm vs 0.183±0.107pm, p= 0.609) but greater with pupil diameter of 6 mm (0.303±0.183pm vs 0.26±0.069 pm, P= 0.40) as compared to the IQ group. Contrast sensitivity was higher in the Tecnis group at 1, 2 and 5 cpd under photopic (not significant) and mesopic (P<0.001, P<0.08, P=0.2, respectively) conditions. Conversely, contrast sensitivity was higher in the IQ group at 10 and 20 cpd under photopic and mesopic conditions (not significant).Conclusion: Tecnis or IQ IOLs seem to be comparable in terms of spherical aberration and contrast sensitivity.
