Inadvertent use of cornea with previous lasik in deep lamellar keratoplasty

Abstract

PURPOSE: To report transplantation of a post-laser in situ keratomileusis (LASIK) donor cornea in a deep anterior lamellar keratoplasty (DALK). CASE REPORT: An 18-year-old male patient with bilateral keratoconus underwent DALK in his right eye. One week postoperatively, the uncorrected visual acuity was 6/24 and the keratometry readings were 36.4/48.6 D in the operated eye. On slit-lamp examination, two interfaces were observed in the corneal stroma. An anterior segment optical coherence tomography (ASOCT; Visante) scan was performed on the operated eye. The ASOCT showed two distinct interfaces, one in the deep corneal stroma close to the Descemet membrane and another interface in the anteri..
