To compare the visual outcomes and wavefront analyses of patients who underwent cataract surgery with the implantation of a Tecnis toric intraocular lens (IOL) (Abbott Medical Optics) with those patients who received an Acrysof IQ toric IOL (Alcon Laboratories Inc).


The study included 40 eyes from 26 patients with regular corneal astigmatism between 1.00 and 3.00 diopters (D) who were undergoing phacoemulsification with implantation of a toric IOL. Patients were randomized into two groups (20 eyes in each group): one group received the Tecnis toric IOL (Tecnis group) and one group received the Acrysof IQ toric IOL (Acrysof group). Over a 2-month follow-up period, the main outcome measures were uncorrected (UDVA) and corrected distance visual acuity (CDVA), spherical equivalent refraction, residual astigmatism, rotational stability of the IOL, and higher order aberrations, measured with a dynamic retinoscopy aberrometer.


At 2-month follow-up, UDVA, CDVA, spherical equivalent refraction, and residual astigmatism showed no statistically significant between-group differences (P=.834, P=.178, P=.447, and P=.166, respectively). No eye had IOL rotation >10°. The toric IOL axis misalignment was similar in both groups (3.15°±2.62° in the Tecnis group and 3.25°±2.04° in the Acrysof group, P=.265). No statistically significant between-group differences were noted for all ocular aberrometry values, except for spherical aberration, which was higher in the Acrysof group (P=.029).


Both studied IOLs promoted good postoperative UDVA, CDVA, and refractive results. Rotational stability was excellent for both IOLs. Postoperative spherical aberration was higher for the Acrysof toric IOL; however, this difference did not seem to affect overall visual quality.
