DLEK

Abbreviation for deep lamellar endothelial keratoplasty.

keratoplasty

(ker'at-o-plas?te) [ kerato- + -plasty] Corneal grafting. The replacement of a cloudy cornea with a transparent one, typically derived from an organ donor. See: lens, corneal contact

deep lamellar endothelial keratoplasty

Abbreviation: DLEK
Transplantation of the two innermost layers of the cornea, Descemet's membrane and the corneal endothelium, leaving the outer cornea layers intact.

Descemet stripping automated endothelial keratoplasty

Abbreviation: DSAEK
Transplantation of the layer of the cornea just anterior to the corneal endothelium with donor tissue after Descemet's membrane has been removed from the recipient's eye. It is used to treat corneal diseases such as Fuchs' corneal dystrophy which impact only the innermost layers of the cornea.

lamellar keratoplasty

Transplantation of donated corneal tissue into the middle layers of the cornea, leaving the corneal endothelium and inner layers of the cornea intact.

optic keratoplasty

The removal of a corneal scar and replacement with corneal tissue.

refractive keratoplasty

Treatment of myopia or hyperopia by removing a portion of the cornea, freezing it in order to reshape it surgically to correct refractive error, and then replacing it after it has thawed. See: keratomileusis

tectonic keratoplasty

Use of corneal tissue to replace that lost because of trauma or disease.

therapeutic penetrating keratoplasty

A treatment for corneal ulceration with perforation or keratitis that has not responded to aggressive medical treatment in which a donated cornea is transplanted into the patient's diseased cornea after the cornea has been completely removed from the eye, the anterior chamber is cleansed, and the lens removed.

deep lamellar endothelial keratoplasty

Abbreviation: DLEK
Transplantation of the two innermost layers of the cornea, Descemet's membrane and the corneal endothelium, leaving the outer cornea layers intact.See also: keratoplasty
