为了评估白内障手术和AcrySof IQ Toric SN 6AT 2人工透镜（IOL）（Alcon Laboratories，Inc.，沃斯堡，德克萨斯州，美国）。本研究是一项回顾性、连续性、单一外科医生系列研究，纳入了接受白内障手术并植入AcrySof IQ Toric SN 6AT 2 IOL的88例患者（术前角膜散光较低）的98只眼。术后1个月获得术后测量值。主要观察指标为单眼远视力和残余屈光散光。术前平均角膜屈光力向量（APV）为0.38±0.09 D。手术和散光矫正型IOL植入后，平均术后屈光APV为0.13±0.10 D。平均术后远裸眼视力为0.08±0.09 logMAR。术后等效球镜屈光度（SER）的平均值为-0.23 0. 22 D，96%的患眼在目标SER的0.50 D范围内。AcrySof IQ Toric SN 6AT 2 IOL对于术前角膜散光水平较低的接受白内障手术的患眼是一种安全有效的选择。
To assess the refractive and visual outcomes following cataract surgery and implantation of the AcrySof IQ Toric SN6AT2 intraolcular lens (IOL) (Alcon Laboratories, Inc., Fort Worth, TX, USA) in patients with low corneal astigmatism. This study is a retrospective, consecutive, single surgeon series of 98 eyes of 88 patients (with low preoperative corneal astigmatism) undergoing cataract surgery and implantation of the AcrySof IQ Toric SN6AT2 IOL. Postoperative measurements were obtained 1-month postsurgery. Main outcome measures were monocular distance visual acuity and residual refractive astigmatism. Mean preoperative corneal astigmatic power vector (APV) was 0.38±0.09 D. Following surgery and implantation of the toric IOL, mean postoperative refractive APV was 0.13±0.10 D. Mean postoperative distance uncorrected visual acuity was 0.08±0.09 logMAR. Postoperative spherical equivalent refraction (SER) resulted in a mean of –0.23±0.22 D, with 96% of eyes falling within 0.50 D of the target SER. The AcrySof IQ Toric SN6AT2 IOL is a safe and effective option for eyes undergoing cataract surgery with low levels of preoperative corneal astigmatism.
