Purpose : To investigate the effect of age and refractive error on higher-order aberrations in adults in their 20∼70s.
Methods : Young (20∼39 years old, 400 eyes), middle-aged (40∼59 years old, 400 eyes) and elderly (60∼79 years old, 400 eyes) people without any ocular disease and refractive surgery were participated in this study. I-Profilerplus was used to measure refractive error and higher-order aberrations in the eyes to analyze the effect of age and refractive error on higher-order aberrations.
Results : As the age increased, the ocular total higher-order aberrations, horizontal and vertical coma aberrations were increased in the positive (+) direction (p<0.050), and the SA (spherical aberration) increased in the negative (-) direction (p<0.050). Coma aberration was larger in the hyperopic eye than myopic eye, and the higher the hyperopic power, the greater the coma, and the lower the myopic power, the greater the coma (p<0.050). Myopic eye had positive (+) SA, and the positive (+) value increases as the myopic power increases (p<0.050).
Hyperopic eye had negative (-) SA, and negative (-) value increased as the hyperopic power increased (p<0.050). The average values of coma and SA were found to have positive (+) values in all age groups, but the people ratio with negative (-) values was high, about 20 to 45%.
Conclusion : The higher-order aberrations can vary according to age, refractive error, and individuals, that it is necessary to design spectacle lenses and contact lenses that can control higher-order aberration to improve visual acuity.
