Excimer laser photorefractive keratectomy (PRK) is widely used for the correction of myopia, astigmatism, and hyperopia.1,2 It has also been used for correction of astigmatism after penetrating keratoplasty.3
Epikeratophakia has been used in the treatment of nontolerant contact lens keratoconous patients.4,5 The epigrafts were made from machined corneal tissue that was found unsuitable for penetrating keratoplasty. Long-term follow-up of pediatric patients who underwent epikeratoplasty for optical correction of aphakia and were corrected for emmetropia revealed that later in life there is delayed myopic regression of the treated eye, which required further correction.6,7 In their patients, Colin et al8 failed to correct this myopic regression with PRK. We describe our experience with PRK for correction of delayed myopic regression of epikeratophakia in 4 eyes.
