PURPOSE: To examine the stability and efficacy of high-cylinder power AcrySof toric intraocular lenses (IOLs), models SN60T6, SN60T7, SN60T8, and SN60T9 (Alcon Laboratories Inc). METHODS: Eligible eyes had cataract and symmetric corneal astigmatism > 2.25 diopters (D). Outcomes included monocular uncorrected distance visual acuity (UDVA), manifest refraction, and assessment of IOL axis. RESULTS: Nineteen eyes from 14 patients had preoperative corneal astigmatism of 4.00 ± 1.10 D. Postoperatively, residual refractive cylinder was 0.55 ± 0.60 D at 3 months. Uncorrected distance visual acuity was 1.3 ± 0.5 logMAR preoperatively and improved to 0.11 ± 0.09 logMAR 3 months postoperatively (P<.0001). All IOLs were stable within 5°. CONCLUSIONS: The IOLs were stable and effective in correcting high amounts of preexisting astigmatism at the time of cataract surgery. Copyright 2012, SLACK Incorporated.
