To assess the clinical consequences of AcrySof toric intraocular lens (IOL) and Hoya toric IOL implantation to correct preexisting corneal astigmatism in patients undergoing cataract surgery.
In this study, we examined 55 eyes of 45 patients with at least 1.00 D corneal astigmatism who were scheduled for cataract surgery. After phacoemulsification, toric IOL was inserted and axis was aligned. We observed the patients, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry, manifest refraction, and IOL axis alignment 6 months after surgery.
After 6 months, the UDVA was 0.17 ± 0.17 logMAR in the AcrySof group and 0.17 ± 0.18 logMar in the Hoya group. More than 78% of eyes in the AcrySof group and 80% of eyes in the Hoya toric IOL achieved a UDVA of 20/40 or better. In the AcrySof group, the mean preoperative corneal astigmatism was 2.73 ± 0.92 D. The mean postoperative refractive astigmatism was 0.84 ± 0.63 D. In the Hoya group, the preoperative corneal astigmatism was 2.58 ± 0.76 D and the postoperative refractive astigmatism was 0.87 ± 0.66 D ( < 0.05). The mean AcrySof IOL axis rotation was 1.88° ± 3.05°. In the Hoya group, the mean axis rotation was 1.53° ± 3.66°. All changes in visual and refractive data before and after surgery were statistically significant ( < 0.05). There was no significant difference between the two groups regarding refractive and visual outcome after surgery ( > 0.05 for all).
Implantation of AcrySof toric IOL and Hoya toric IOL was an effective way to correct preexisting corneal astigmatism in cataract surgery.
评估在白内障手术患者中植入爱尔康散光型人工晶状体（IOL）和豪雅散光型IOL以矫正术前角膜散光的临床效果。
在本研究中，我们检查了45例计划进行白内障手术且角膜散光至少为1.00 D的患者的55只眼睛。超声乳化术后，植入散光型IOL并调整轴位。我们在术后6个月观察患者的未矫正远视力（UDVA）、矫正远视力（CDVA）、角膜曲率测量、显验光和IOL轴位对准情况。
6个月后，爱尔康组的UDVA为0.17±0.17 logMAR，豪雅组为0.17±0.18 logMar。爱尔康组超过78%的眼睛和豪雅散光型IOL组80%的眼睛UDVA达到20/40或更好。在爱尔康组，术前平均角膜散光为2.73±0.92 D。术后平均屈光性散光为0.84±0.63 D。在豪雅组，术前角膜散光为2.58±0.76 D，术后屈光性散光为0.87±0.66 D（<0.05）。爱尔康IOL平均轴旋转为1.88°±3.05°。在豪雅组，平均轴旋转为1.53°±3.66°。手术前后视力和屈光数据的所有变化均具有统计学意义（<0.05）。两组术后屈光和视力结果之间无显著差异（所有均>0.05）。
植入爱尔康散光型IOL和豪雅散光型IOL是矫正白内障手术中术前角膜散光的有效方法。
