ASTIGMATISM, SECONDARY, COMA
The iTrace aberrometer (Tracey Technologies, United States) was used to measure ocular HOAs following 10 min of dark adaptation without pharmacological pupil dilatation before the operation and at the follow-ups. The root means square values of total HOAs, spherical aberration, secondary astigmatism, coma aberration, and trefoil aberration were recorded.
