[Total posterior cryopexy of the cornea in the treatment of chronic bullous keratopathy].
The proposed method, in contrast to methods used in the treatment of bullous chronic keratopathy with the painful syndrome, suggests cryo applications on the entire posterior surface of the cornea through a short (2.5-3 mm) corneal or scleral incision. Posterior cryopexy can be combined (if necessary) with other reconstructive interventions (anterior vitrectomy, separation of synechiae, reposition of intraocular lens, antiglaucoma surgery). The intervention leads to the formation of a semipermeable fibrocellular film representing a cicatricial biological barrier at the level of endothelial Descemet's membrane for chamber humor. Total posterior cryopexy of the cornea relieves pain due to antiedematous effect, which was noted clinically, by evaluation of corneal permeability by keratopenetrofluorometry, and from improvement of visual acuity.
