Nordan epikeratophakia technique (NET) is described for the treatment of hyperopia and the results in eight eyes are reported (mean = +5.09 +/- 0.85 diopters preoperatively and -2.09 +/- 1.22 diopters postoperatively). The Nordan epikeratophakia technique is a modification of Kaufman-McDonald epikeratophakia with advantages that are described. Data are analyzed according to traditional means in addition to newer indices that consider both the uncorrected visual acuity and the refractive error.
