Subjective Evaluation of Defocus and Astigmatism Combinations Using Image Simulation in Presbyopes

CONCLUSIONS Accommodation may play a role when comparing optical and simulated defocus and astigmatism combinations. Presbyopic subjects are able to produce a low level of accommodation that may counterbalance a part of the deleterious effect of the astigmatism on image quality. Simulation remains a useful tool if the correct accommodation state is taken into account.
