【Purpose】This study aimed to assess the effects of soft contact lens (SCL) materials on higher-order aberrations.
【Subjects and Methods】Subjects were 43 eyes of 43 young healthy SCLs users who had no ocular diseases except refractive errors. The subjects were divided into two groups: 21 (21 eyes) who used hydrogel SCLs (the HyCL group) and 22 (22 eyes) who used silicone hydrogel SCLs (the SHCL group). Both groups used daily disposable SCLs and those who used aspheric SCLs were excluded. Using a wavefront analyzer KR-1W (TOPCON), we measured higher-order aberrations. All ocular higher-order aberrations expressed in root mean square were analyzed among ocular aberrations obtained with an analytical pupil diameter of 4 mm and 10 times for 10 s with the opened eyelids in the dry-eye mode, and the average value was evaluated. This study compared higher-order aberrations before and after wearing SCLs between or within group respectively. Mann-Whitney U test and Wilcoxon signed-rank test were used for statistical analysis.
【Results】No statistically significant differences were observed in higher-order aberrations between or within group comparisons and in continuous measurements in the dry-eye mode.
【Conclusion】These findings suggested that SCL materials have a lesser impact on higher-order aberrations.
