Abstract

Purpose: To compare Tecnis Z9000 and Akreos AO aspheric intraocular lenses (IOLs) in terms of spherical aberration and contrast sensitivity.Methods: Thirty-four eyes of 34 patients undergoing phacoemulsification cataract surgery were randomly assigned for implantation of Tecnis or Akreos AO IOLs. Three months postoperatively, bestcorrected 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 0.076±0.080 logMAR in the Tecnis group and 0.115±0.090 logMAR in the AO group (P=0.33). Spherical aberration with 4 mm and 6 mm pupil diameters in the Tecnis group was less than the AO group (0.140±0.097mm vs 0.285±0.087mm, P< 0.001 and 0.303±0.183mm vs 0.329±0.083mm, P=0.4, respectively). Contrast sensitivity was significantly higher in the Tecnis group at 1, 2, 5 and 10 cpd under photopic and at 1, 2 and 10 cpd under mesopic conditions.Conclusion: Tecnis Z9000 IOL seems to entail better visual outcomes in terms of spherical aberration and contrast sensitivity compared to Akreos AO IOL.
