The average weighted root-mean-square spot-size (wRMS) ± standard deviation for centered intraocular lenses (IOLs) as a function of the iris diameter (a) in the normal group and (b) in the keratoconus group. The values of the aberration-neutral IOL (nIOL) are displayed as black dots, those of the custom IOL (cIOL) as red crosses.
