Purpose: To compare the AcrySof Toric intraocular lens (IOL) and an AcrySof spherical control IOL and to investigate correction capability of the AcrySof Toric IOL in subjects with cataracts and corneal astigmatism.
Design: Comparative case series.
Methods: This retrospective review of clinical records comprised 98 eyes with 1.5 to 4.5 diopters (D) of preoperative corneal astigmatism who had cataract surgery and AcrySof T3/T4/T5 toric or AcrySof IQ spherical monofocal IOL implantation. Surgically induced astigmatism (SIA) was calculated for eyes with postoperative keratometry results. The main outcome measures include visual acuity outcomes, Residual astigmatism, IOL position, patient-reported spectacle use, and safety.
Results: One year postoperatively, best spectacle-corrected distance visual acuity of 0.8 was 71% (Toric IOL) versus 67% (control IOL). Uncorrected distance visual acuity of 0.8 or better was 62% (Toric IOL) versus 21% (control IOL; P<0.05). Mean absolute residual refractive cylinder was 0.42 D (Toric IOL) versus 1.36D (control IOL; P<0.01). Mean rotation was 3.21°±1.25° (range, 0°–20°) for the Toric IOL. Three-month spectacle freedom was 57.0% (Toric IOL) and 34.1% (control IOL; P<0.01). Complications in both groups were few and were as would be expected with cataract surgery.
Conclusions: The mean refractive astigmatism after cataract surgery in patients with 1.5 D to 4.5 D of corneal astigmatism was significantly lower when a toric IOL was implanted. The safety results, efficacy and rotational stability support the use of the AcrySof Toric IOL for patients with cataracts and high degree of corneal astigmatism.
