Title
(EN) COLLAGEN TREATMENT APPARATUS AND METHOD
(FR) APPAREIL ET METHODE POUR LE TRAITEMENT DE COLLAGENE
Abstract
(EN)
A method and apparatus for controlled thermal shrinkage of collagen tissue by irradiation with coherent energy in the wavelength band of 1.80 to 2.55 microns as generated by a laser. A specific application to ophthalmological corneal reshaping is described. The apparatus consists of a corneal mapping system (33), laser (36), and computer (35).
(FR)
Méthode et appareil permettant le rétrécissement thermal contrôlé de tissu de collagène par irradiation avec une énergie cohérente dans la bande de longueur d'ondes de 1,80 à 2,55 microns, lesdites ondes étant genérées par un laser. Une application spécifique au reprofilage de la cornée ophthalmologique est décrite. L'appareil comporte un système de localisation (33), un laser (36) et un ordinateur (35).
