Change in Efficiency of Aspheric Intraocular Lenses Based on Pupil Diameter
We read with interest the article by Eom and associates on aspheric intraocular lens performance. The authors stated that “aberrations of the cornea increase with age.” Although according to recent studies this is true for all corneal higher-order aberrations, it is very important to highlight that the amount of change of those aberrations with age has been found to be far less (approximately half) than the change in total ocular higher-order aberrations. Furthermore, specifically with regard to corneal spherical aberration, it has been shown to be stable with age.
