To examine the stability and efficacy of high-cylinder power AcrySof toric intraocular lenses (IOLs), models SN60T6, SN60T7, SN60T8, and SN60T9 (Alcon Laboratories Inc).
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.
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°.
The IOLs were stable and effective in correcting high amounts of preexisting astigmatism at the time of cataract surgery.
研究高筒力 AcrySof toric 人工晶状体（IOL）模型 SN60T6、SN60T7、SN60T8 和 SN60T9（爱尔康实验室公司）的稳定性和疗效。
符合条件的眼患有白内障和对称角膜散光＞2.25 屈光度（D）。结果包括单眼未矫正远视力（UDVA）、显折射和 IOL 轴评估。
14 例患者的 19 只眼术前角膜散光为 4.00±1.10 D。术后 3 个月时残余屈光柱为 0.55±0.60 D。术前未矫正远视力为 1.3±0.5 logMAR，术后 3 个月改善至 0.11±0.09 logMAR（P＜0.0001）。所有 IOL 均稳定在 5°以内。
在白内障手术时，这些 IOL 能稳定有效地矫正大量的术前散光。
