Effects of Reference Axes Used During Measurements of Ocular and Corneal Higher-Order Aberrations in Patients Following LASIK

Abstract

The HOAs were significantly different depending on the axes used and should be described on the basis of a common axis. These results suggest that the anterior surface of the normal or post-LASIK cornea is more rotationally symmetrical along the VN than along the LOS.

Serial Measurements of Higher-Order Aberrations after Blinking in Patients with Dry Eye

“…When the pattern of the sequential changes in ocular total HOAs is stable or has small fluctuations within the normal range of total HOAs, it is difficult to differentiate between normal eyes and eyes with mild dry eye without SPK in the central cornea. Because the importance of spatial location and wavefront aberrations has been reported, [25][26][27][28] further studies would be helpful in evaluating the relationship between the spatial location and HOAs.…”
