Values are presented as mean ± standard deviation (range) or number
D = diopters; AK = arcuate keratotomy; IOL = intraocular lens; ATR = against-the-rule; WTR = with-the-rule; UDVA = uncorrected distance visual acuity; CDVA = corrected distance visual acuity; logMAR = logarithm of the minimum angle of resolution
