To evaluate the changes in higher order aberrations (HOAs) after implantable collamer lens (ICL; Staar Surgical, Nidau, Switzerland) implantation.
Totally 30 eyes of 18 patients with myopia were included in this study with an average age of 25.77y (min: 21, max: 40). Refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), HOAs (entire, corneal and internal) were evaluated preoperatively and three months postoperatively. Ocular aberrations were measured by using iTrace (Tracey Technology, Houston, Texas, USA). SPSS (IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp) was used for the statistical analysis and the interpretation of the data. values of less than 0.05 were considered statistically significant.
The preoperative mean spherical power was -9.01 D (min: -5.00, max: -13.00) and the mean cylindrical error was -2.40 D (min: -0.50, max: -4.75). The postoperative mean residual spherical power was -0.73 D (min: -0.20, max: -1.75) and the mean cylindrical error was -0.89 D (min: -0.18, max: -2.09). Analyses were made on root mean square (RMS) values of total HOAs (tHOAs), spherical aberration, coma and trefoil as entire, corneal and internal components. The differences in entire tHOAs and in internal tHOAs were significant. There was no significant change found in spherical aberrations. The differences in entire coma and in internal coma were significant. There was no significant change found in corneal coma. With respect to trefoil, the only significant difference was in internal trefoil.
The ICL implantation corrects the refractive error successfully and changes entire and internal HOAs of the eye.
评估植入式可矫正晶状体（ICL；瑞士尼道斯塔手术公司）植入术后高阶像差（HOA）的变化。
本研究共纳入18例近视患者的30只眼，平均年龄25.77岁（最小21岁，最大40岁）。术前及术后三个月评估屈光、未矫正远视力（UDVA）、矫正远视力（CDVA）、高阶像差（整体、角膜和眼内）。使用iTrace（美国得克萨斯州休斯顿Tracey技术公司）测量眼像差。采用SPSS（IBM公司，2013年发布。适用于Windows的IBM SPSS Statistics，版本22.0。纽约州阿蒙克：IBM公司）进行统计分析和数据解读。小于0.05的值被认为具有统计学意义。
术前平均球镜度数为-9.01D（最小-5.00，最大-13.00），平均柱镜度数为-2.40D（最小-0.50，最大-4.75）。术后平均残余球镜度数为-0.73D（最小-0.20，最大-1.75），平均柱镜度数为-0.89D（最小-0.18，最大-2.09）。对总高阶像差（tHOA）、球差、彗差和三叶草像差的均方根（RMS）值进行整体、角膜和眼内成分分析。整体tHOA和眼内tHOA的差异具有统计学意义。球差无显著变化。整体彗差和眼内彗差的差异具有统计学意义。角膜彗差无显著变化。关于三叶草像差，唯一显著差异在于眼内三叶草像差。
ICL植入术成功矫正屈光不正并改变眼的整体和眼内高阶像差。
