Light distortion and spherical aberration for the accommodating and nonaccommodating eye

To evaluate how different amounts of induced spherical aberration (SA) affect the light distortion (LD) phenomena, tests were performed using an experimental device to measure the distortion (haloes, glare, and so on) of a point source. To simulate the effect of SA, eight different phase plates betw...

To simulate the effect of SA, eight different phase plates between +0.300 and −0.300  μm of SA for a 5-mm aperture were used in a random and double-masked experimental design. Measurements were performed at a distance of 2 m in a darkened room in 10 eyes of five subjects with a mean age of 26.4±6.1 years and a mean refractive error of −0.50±0.70  D. Data were obtained with natural pupil and after pupil dilatation. The measurements with this experimental system showed a significant increase in all distortion parameters with cycloplegia for the phase plates with the higher positive SA (+0.300 and +0.150  μm). The disturbance index increased from 14.86±6.12% to 57.98±36.20% (p<0.05) with the +0.300  μm plate. The same effect was observed through at a much lower rate when the eye could accommodate.
