keratoplasty

Excision of corneal tissue and its replacement by a cornea from a human donor. This can be done either over the entire cornea (total keratoplasty) or over a portion of it (partial keratoplasty). Two main techniques are used: (1) the penetrating keratoplasty in which the entire thickness of the cornea is removed and replaced by transparent corneal tissue; (2) the lamellar keratoplasty in which a superficial layer is removed and replaced by healthy tissue. Common indications to perform keratoplasty are therapeutic (e.g. keratoconus, corneal ulcer) or cosmetic (e.g. removing an unsightly opacity). Syn. corneal transplant. See ciclosporin; granular dystrophy; eye bank; corneal graft; immunosuppressants.

The main advantage over penetrating keratoplasty is that it has virtually no effect on the corneal surface, thereby maintaining its natural shape and avoiding the potentially large refractive changes of corneal suturing (see Figure 6).

The surgical treatment was penetrating keratoplasty for 10 eyes and anterior lamellar keratoplasty for 7 eyes.
