摘要
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。
AIM:To investigate the refractive outcomes and changes of corneal astigmatism and higher-order aberrations(HOAs)after Toric implantable Collamer lens implantation(Toric ICL).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.
