<unk>  (also known as epikeratoplasty and onlay lamellar keratoplasty) 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. __TOC__
