目的:对比植入AcrySof Toric人工晶状体与AcrySof球面人工晶状体术后的临床效果。方法:收集确诊为老年性白内障并伴有规则角膜散光的患者56例63眼,按照患者自愿原则,分别植入AcrySof Toric人工晶状体(实验组)27例30眼;AcrySofNatural球面人工晶状体(对照组)29例33眼。均施行白内障超声乳化摘除联合人工晶状体植入术,随访时间6mo。观察两组患者术后裸眼远视力、最佳矫正远视力、术前术后角膜散光变化情况、术后散光、AcrySofToric人工晶状体轴位稳定性。结果:两组患者术后1wk,6mo裸眼视力,实验组明显优于对照组,比较差异均有统计学意义(P<0.05),两组患者术后1wk,6mo散光比较差异均有统计学意义(P<0.05)。两组患者术前与术后6mo的角膜散光比较,差异均无统计学意义。术后AcrySof Toric IOL的轴位移动度,术后1d;1wk;1,6moIOL平均轴位移动度分别为:(4.22±1·69)°,(4.64±1.97)°,(4.87±1.91)°,(5.39±1·56)°,差异无统计学意义(F=2.259,P>0.05)。术后6mo96.67%的患眼轴位移动度<10°。结论:与普通球面人工晶状体比较,AcrySof Toric人工晶状体能安全、有效、稳定矫正白内障患者的角膜散光,具有良好的轴位移动稳定性。

AIM:To compare clinical outcomes on pseudophakic patients with AcrySof Toric and patients with AcrySof spherical intraocular lens(IOL).METHODS: A total of 56 age-related cataract patients (63 eyes) with corneal astigmatism more than 1.00 D were enrolled and divided into two groups. Experimental group: 27 cases (30 eyes), AcrySof Toric IOL was implanted after phacoemulsification. Control group: 29 cases (33 eyes), AcrySof Natural spherical IOL was implanted after phacoemulsification. A 6-month follow-up was planned. The uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), preoperative and postoperative corneal astigmatism, postoperative refractive cylinder, toric IOL axis rotational stability were measured .RESULTS: The UCDVA at 1 week and 6 months postoperatively were significantly better in experimental group compared with control group (P<0.05). The mean refractive cylinder at 1 week and 6 months postoperatively were superior in experimental group, there were statistically differences between the two groups(P<0.05). The mean postoperative toric IOL rotation was 4.22±1.69 degrees, 4.64±1.97 degrees, 4.87±1.91 degrees, 5.39±1.56 degrees at 1 day, 1 week, 1 month, 6 months, respectively. There were no significant differences among the different months(P>0.05), the axis rotation was within 10 degrees in 96.67% of all eyes.CONCLUSION: Compared with AcrySof spherical IOL, AcrySof Toric IOL provides a safe, effective, stable method for correcting corneal astigmatism in cataract patients and show good rotational stability.
