The AcrySof Toric intraocular lens in subjects with cataracts and corneal astigmatism: a randomized, subject-masked, parallel-group, 1-year study.

To compare the AcrySof Toric intraocular lens (IOL) and an AcrySof spherical control IOL and to investigate rotational stability of the AcrySof Toric IOL (Alcon Laboratories, Inc., Fort Worth, TX) in subjects with cataracts and preexisting corneal astigmatism. Randomized, subject-masked, parallel-group, multicenter, 1-year study. We included 517 subjects (Toric IOL, n = 256; control IOL, n = 261). Unilateral implantation of an AcrySof Toric or AcrySof spherical control IOL (spherical powers, 12.00-25.00 diopters [D]; cylinder powers 1.50, 2.25, or 3.00 D for corneal astigmatism correction of 0.75 to < 1.50, ≥ 1.50 to <2.00, and ≥ 2.00 D with no upper limit, respectively). No limbal relaxing incisions were permitted. Visual acuity outcomes, IOL position, patient-reported spectacle use, and safety. One year postoperatively, best spectacle-corrected distance visual acuity of ≥ 20/20 was 77.7% (Toric IOL) versus 69.2% (control IOL). Uncorrected distance visual acuity of 20/20 or better was 40.7% (Toric IOL) versus 19.4% (control IOL; P<0.05). Mean absolute residual refractive cylinder was 0.59 D (Toric IOL) versus 1.22 D (control IOL; P<0.0001). Mean rotation was < 4° (range, 0°-20°) for the Toric IOL. Six-month spectacle freedom was 61.0% (Toric IOL) and 36.4% (control IOL; P < 0.0001). Complications in both groups were few and were as would be expected with cataract surgery. Favorable efficacy, rotational stability, distance vision spectacle freedom, and safety results support the use of the AcrySof Toric IOL for patients with cataracts and corneal astigmatism.

Comparison of the visual outcomes and OPD-scan results of AMO Tecnis toric and Alcon Acrysof IQ toric intraocular lenses.

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.

Comparison of clinical and patient-reported outcomes with bilateral AcrySof toric or spherical control intraocular lenses.

To compare clinical and patient-reported outcomes with bilateral implantation of AcrySof toric or spherical control (Alcon Laboratories Inc) intraocular lenses (IOLs). Patients with cataract and corneal astigmatism who previously received either an AcrySof toric IOL or an AcrySof spherical control IOL were offered implantation of the same IOL in the fellow eye. Six-month assessments included visual acuity, refractive cylinder, spectacle use, and patient satisfaction. The study included 62 patients (toric, n=40; control, n=22). All corneal incisions were temporal, with final mean incision sizes of 3.0 mm for the toric IOL and 3.1 mm for the spherical control IOL. A significantly greater proportion of patients with toric IOLs achieved spectacle independence for distance vision and did not require prescription glasses for near or distance vision (P=.0190). Patients with toric IOLs had significantly less residual refractive cylinder (P<.0001) and better binocular distance uncorrected visual acuity (UCVA) (P=.0014) than those with spherical control IOLs. Patients with bilateral AcrySof toric IOLs achieved superior spectacle freedom, residual refractive cylinder, and distance UCVA compared to patients with bilateral spherical control IOLs.
