ZARRANZ-VENTURA, J. et al. Acrysof^® toric intraocular lens implantation in cataract surgery. Arch Soc Esp Oftalmol [online]. 2010, vol.85, n.8, pp.274-277. ISSN 0365-6691.

Aim: To assess the medium term outcomes of Acrysof^® toric intraocular lens implantation in 54 patients (54 eyes). Methods: Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), preoperative astigmatism, residual postoperative astigmatism, and global average and model-specific intraocular lens (IOL) rotation grade were analyzed. Results: At 2-months of follow-up,the mean UCVA was 0.83 (SD: 0.14) Snellen scale, with 73.9% of the patients >0.8, and 32.6% with 1.0. Mean BCVA achieved was 0.94 (SD: 0.10). Mean preoperatory astigmatism was -2.25 diopters (D) (SD: 0.78), and mean postoperative astigmatism was -0.32 D (SD: 0.56), with significant differences between both groups (p<0.001). Model-specific mean residual astigmatism was -0.1 D for T3, -0.27 D for T4 and -0.43 D for T5, without significant differences between the three models (p=0.483). Mean IOL-axis rotation grade was 3.87±3.25 degrees, with 91.6% of implanted lens within 10^o of predicted axis. Discussion: T3, T4 and T5 Acrysof^® Toric intraocular lenses can correct preoperative astigmatism with a high success rate in terms of UCVA, and residual postoperative astigmatism, with minimum IOL-rotation grade at 2 months follow-up period.
