| Abstract |
|
Full-thickness lamellar keratoplasty is a surgical method for corneal allografting, in which a full thickness corneal donor button without endothelium is transplanted deep into the lamellar bed of a recipient's cornea. Lamellar keratoplasty is indicated for tectonic, therapbeutic, or optical reasons. Usually the visual result with lamellar keratoplasty performed for optical purposes is less rewarding than penetrating keratoplasty. However the advantages of the lamellar graft are as follows: (1) the age limit of the donor material can be extended because the endothelium is not transplanted; (2) a lamellar graft is an extraocular procedure, and the complications in intraocular surgery can be avoided; and (3) there is no restriction as to size of the graft. We obtained good results from full-tickness deep lamellar keratoplasty on patients with granular corneal dystrophy, macular corneal dystrophy, keratoconus, and corneal scars(in cases of intact endothelium), in which penetrating keratoplasty used to be performed in the past. |
