Purpose : To investigate the effects of age, refractive errors, pupil diameter, pupil center shift, corneal refractive power, and corneal astigmatism on higher order aberrations (HOAs) in middle aged adult.
Methods : The middle subjects aged 40 to 59 years who had no ophthalmologic diseases and refractive surgery were recruited. I-Profilerplus (Zeiss, Berlin, Germany) was used to measure HOAs and refractive errors, pupil diameter, pupil center shift, corneal refractive power, and corneal astigmatism, and the effect of the measured values on HOAs were analyzed.
Results : The total HOAs of the eye increased in a positive (+) direction with increasing age, corneal refractive power, and corneal astigmatism increased (all, p<0.050), and as the refractive errors increased in the minus (-) direction and as the pupil diameter increased, it increased in the negative (-) direction (all, p<0.050). Horizontal coma and vertical coma aberration increased in the positive (+) direction as age and corneal astigmatism increased, while horizontal coma increased in the positive (+) direction as the pupil center shifted to the lateral side and vertical coma increased to the upper side (all, p<0.050), As refractive errors increased in the minus (-) direction, and as the pupil diameter increased, it increased in the negative (-) direction (all, p<0.050). Spherical aberration increased in the positive (+) direction as refractive errors was higher in the minus (-) direction, and as the pupil diameter, corneal refractive power, and corneal astigmatism increased.
(all, p<0.050), and increased in the negative (-) direction with increasing age (all, p<0.050).
Conclusion : The ocular HOAs of the middle aged changes according to age, refractive errors, pupil diameter, pupil center shift, corneal refractive power, and corneal astigmatism. These results would be cornerstones in designing lenses for spectacle and contact lens.
