The rationale application of donor material: original ten years experience, possible ways of development and literature data

Abstract


Lately, layer-wise keratoplasty became the first operation of choice in case of pathology of cornea. In view of satisfying results of endothelial surgery similar operations are implemented at earlier stages that increases need in donor tissue. With increasing of life span of population, also increases number of patients in need of transplantation of cornea. The number of intact cadaver cornea decreases because of stable increase of surgical interventions on front segment of eye. The present article presents original ten years experience concerning optimization of application of donor tissue and indicate on possibilities of further increasing of number of applied keratoplasties. From 2009 to 2015 in the Helmholtz Moscow research institute of eyes diseases 652 transplantations of cornea were implemented in various modifications: straight-through keratoplasty, transplantation of Descemet's membrane with endothelium (DMEK), deep front layer-wise keratoplasty, endokeratoplasty (DSEK) with various modes of transplant formation and 23 frontal layer-wise keratoplasties. In transplantation were also used eyes of donors with radial keratotomy, after laser keratomileusis and with artificial intra-ocular lens. To implement 652 operations 528 cadaver eyes with average age 41 ± 32,5 years (varying from 21 to 87 years) were required. The number of transplantations increased approximately on 50% at potential up to 75%. The lamellar surgery permits using corneal donor tissue with altered frontal surface and to increase number of transplantations of cornea. The renunciation of application of corneal donor tissue with altered frontal surface is inexpedient.
