Table 2 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.

From: Keratoconic eyes with stable corneal tomography could benefit more from custom intraocular lens design than normal eyes
