The Averaged Preoperative Mean WFE W_meanpre(x₀, y₀), Computed for 3.5- and 6-mm PDs

PD (mm)	Log BCVSOTF	Total HOA RMS (μm)	Coma RMS (μm)	SA RMS (μm)	rHOA RMS (μm)
3.5	−0.05	0.036	0.031	0.012	0.014
6.0	−0.38	0.185	0.145	0.078	0.083

For all calculations LOA were set to zero. BCVSOTF (visual Strehl ratio based on the optical transfer function, simulated for best correction); total HOA RMS, root mean square value of 3rd- to 6th-order aberrations; coma RMS, RMS of 3rd to 5th order coma; SA RMS, RMS of Z₄⁰ and Z₆⁰; rHOA RMS, residual RMS of all noncoma, nonspherical HOA.
