Comparison of wavefront aberrations under cycloplegic, scotopic and photopic conditions using WaveScan

Abstract

Purpose: To evaluate the differences of wavefront aberrations under cycloplegic, sco topic and photopic conditions. Methods: A total of 174 eyes of 105 patients were measured using the wavefront sensor (WaveScan ® 3.62) under different pupil conditions: cycloplegic 8.58 ± 0.54 mm

Differences in central and non‐central keratoconus, and their effect on the objective screening thresholds for keratoconus

“…; Fan et al. ). Also, this change in HOA has been noted to be of higher magnitude in keratoconus compared to normal controls (Atchison et al.…”

Effect of Single Administration of Coffee on Pupil Size and Ocular Wavefront Aberration Measurements in Healthy Subjects

“…The WA have been reported to be different under different pupillary conditions [ 27 ]. Fan et al [ 28 ] found that all the HOAs decreased statistically and significantly as the pupil size gets smaller. Supportively, in our study, we observed that changes in total HOAs were positively correlated with the changes in pupil size at each time point.…”
