Epikeratophakia [1] (also known as epikeratoplasty and onlay lamellar keratoplasty[2]) is a refractive surgical procedure in which a lamella of a donor cornea is transplanted onto the anterior surface of the patient's cornea. A lamellar disc from a donor cornea is placed over the de-epithelialized host cornea and sutured into a prepared groove on the host cornea. Indications include treatment of keratoconus, refractive errors like myopia and high hypermetropia including aphakia, which cannot be corrected with conservative methods.[2]

Complications
Common complications of epikeratophakia include delayed post operative visual recovery, reduced best corrected visual acuity, prolonged epithelial defects and irregular astigmatism.[3][2]
History
In 1949, José Barraquer introduced refractive procedure of inclusion of a lenticule within the corneal stromal layer. In 1980s, based on Barraquer's procedure, Werblin, Kaufman and Klyce at the LSU Eye Center introduced epikeratophakia.[4]
