(FR) SEGMENTS CORNÉENS MIS EN FORME : DISPOSITIFS INTRASTROMAUX CORNÉENS ALLOGÉNIQUES (SEGMENTS ANNULAIRES ET ANNEAUX, DISQUES MODIFIÉS, MODIFICATIONS) POUR INDUIRE UN CHANGEMENT DE FORME, UNE RÉGULARISATION ET UNE STABILISATION DE LA CORNÉE DANS UNE KÉRATECTASIE ET D'AUTRES AFFECTIONS DE LA CORNÉE ET POUR LA CORRECTION D'AMÉTROPIES
Abstract:
(EN) Allogenic device (corneal or scleral or bioengineered material including but not limited to processed collagen) as well as modifications of these are used in the form of intra-stromal ring segments, rings, modified discs and modifications to induce shape change, refractive change, improve corneal irregularity, customize and improve corneal surface, provide better biomechanical strength distribution, give ability to implant even in corneas with less than 400 microns thickness in the zone of implantation, ability to implant at varying depths, have less chances for complications such as segment migration; over-riding; stromal thinning, corneal melt, necrosis and infection; exposure and extrusion of the segment; channel deposits and corneal haze.
