Purpose |
To study the effect of accommodation on ocular aberrations.
Design |
Observational case series.
Methods |
The ocular aberrations in 33 eyes of 33 young adults were measured with a Hartmann–Shack wavefront aberrometer before and during 3 diopters of accommodation.
Results |
The root mean square values of wavefront error did not change for a 4-mm and a 6-mm zone; however, spherical aberration changed significantly toward negativity for both the 4-mm zone (P < .001) and 6-mm zone (P = .022).
Conclusions |
During accommodation, the significant change in spherical aberration occurs without a change of image quality. Therefore, for customized aberration, it may not be advantageous to eliminate the physiologic spherical aberration for far vision.
