目的：研究Toric植入术(ICL)的临床疗效以及对角膜散光和高阶像差(HOA)的影响。

方法：前瞻性非随机临床实验研究。共纳入57例患者102眼行Toric ICL植入术以矫治近视散光。分别于术前和术后6mo测量裸眼视力、最适屈光度、最佳矫治视力、最适散光度、角膜散光、高阶像差并记录。检查仪器为角膜地形图、眼前节分析系统和波前像差分析仪。

结果：术后93.80%患眼等效球镜≤-1.00D， 85.30%患眼等效球镜≤-0.5D。术后66.30%患眼裸眼视力≥20/25，65.50%患眼裸眼视力≥20/20； 角膜散光和高阶像差手术前后比较没有统计学意义。全眼三叶草和彗差手术前后比较差异无统计学意义。

结论：所有眼球的近视和散光得到有效矫治。角膜切口对高阶像差和散光没有影响。

METHODS: Prospective nonrandomized clinical trial studies. This study included 102 eyes of 57 patients underwent Toric ICL for myopic astigmatism correction. Uncorrected visual acuity(UCVA), manifest refraction, best spectacle-corrected visual acuity(BSCVA), manifest refractive cylinder, the corneal astigmatism and HOAs were measured preoperatively and up to 6mo after surgery. The vectors were measured using corneal topography, the Pentacam HR system and Wavefront analyzer.

RESULTS:Postoperative, the percentage of eyes had a spherical equivalent refraction within -1.00 D were 93.80%. The percentage of eyes within -0.50 D of emmetropia were 85.30%. The percentage of eyes which postoperative UCVA ≥20/25 was 66.30% and the percentage of eyes which postoperative UCVA ≥20/20 was 65.50%. The corneal astigmatism and aberrations preoperatively showed no statistical significance compared with postoperative. The total eyes aberrations and coma resulted in slight changes and had no statistically significant.

CONCLUSION:The corneal incision of Toric ICL implantation caused no changes in astigmatism and higher-order wavefront aberrations of cornea.
