Wavefront measurements along the primary line of sight and across the central \u00b120\u00b0 of the horizontal retina were acquired using a pyramidal aberrometer, while subjects accommodated to high\u2010contrast letter stimuli (6\/12 equivalent) at six target vergences (\u22120.25 and \u22121.00 to \u22125.00 D).
