Weighted root-mean-square (RMS) spot-size and RMS wavefront-error (average ± standard deviation, range) with a centered intraocular lens (IOL) in the normal group and the keratoconus group.

Group	IOL	wRMS (μm)	RMS wavefront-error (μm)
normal	nIOL	25.53 ± 4.31 (16.4…30.3)	1.116 ± 0.268 (0.743…1.601)
	cIOL	2.40 ± 0.78 (1.5…4.5)	0.016 ± 0.004 (0.010…0.027)
keratoconus	nIOL	102.13 ± 37.8 (49.8…180.2)	5.540 ± 2.505 (2.325…11.66)
	cIOL	2.98 ± 1.87 (1.9…8.5)	0.017 ± 0.005 (0.012…0.026)

IOL: intraocular lens, cIOL: custom IOL, nIOL: aberration-neutral IOL, wRMS: weighted root-mean-square spot-size, RMS: root-mean-square.
