Abstract
PURPOSE
In this study evaluated clinical outcomes and higher-order aberrations in patients with implanted Tecnis ZCT toric intraocular lens (IOL) (Abbott Medical Optics Inc., Santa Ana, CA, USA) and the Zeiss AT TORBI toric IOL (Carl Zeiss Meditec AG, Jena, Germany) in eyes with low to moderate corneal astigmatism. METHODS: We conducted a retrospective study of 32 consecutive eyes of 26 patients with a visually significant cataract and moderate corneal astigmatism (higher than 1.25 diopter [D] and lower than 4.5 D) undergoing cataract surgery with implantation of the aspheric Tecnis ZCT toric IOL (Abbott Medical Optics Inc.) and the Zeiss AT TORBI toric IOL (Carl Zeiss Meditec AG). Phacoemulsification was performed by the same experienced surgeon using 2.2 mm temporal incision. Visual, refractive and aberrometric changes were evaluated during a 3-month follow-up. Power vector analysis of Cartesian astigmatism (J0) and oblique astigmatism (J45) was performed. RESULTS: At the 3-month follow-up, corrected distance visual acuity (CDVA) and residual astigmatism showed no statistically significant differences between groups (p = 0.203 and p = 0.364, respectively). Pre- and postoperative J0 were 0.71 +/- 0.84 and 0.05 +/- 0.39 in the Tecnis Toric group and, 0.88 +/- 1.27 and -0.02 +/- 0.16 in the AT TORBI group, respectively, which showed statistically significant differences (p = 0.029 and p = 0.032, respectively). Pre- and post-operative differences of J0 and J45 were not statistically significant (p = 0.234 and p = 0.603, respectively). No eye had IOL rotation > or =10degrees. Ocular aberrometry values were statistically significantly differenct between the groups, except for spherical aberration, which was higher in the AT TORBI group (p = 0.0047). CONCLUSIONS: Both IOLs showed good postoperative uncorrected distance visual acuity, CDVA and refractive results in this study. Rotational stability was excellent for both IOLs until the 3-month follow-up.
