Abstract

Translated fromPortuguese

Patente de Invenção: "DISPOSITIVO PARA IMPLANTE INTRACORNEANO E PROCESSO PARA TRATAMENTO DE DEFORMIDADES DA CóRNEA"<D>. A presente invenção refere-se a um dispositivo para implante intracorneano compreendendo um corpo sólido ou gelatinoso constituído por um polímero biocompatível tendo pelo menos uma superfície externa, sendo que a referida superfície externa possui, aplicado sobre ela como um revestimento, um material reativo para com o polímero biocompatível e covalentemente ligado ao corpo do dispositivo de implante, o referido material reativo apresentando características químicas semelhantes à substância fundamental da córnea. O dispositivo da invenção é adequado para o tratamento de deformidades da córnea tais como ceratocone, astigmatismos irregulares pós-transplantes de córnea e pós-cirurgias refrativas corneanas Lasik e PRK, miopias e outras ametropias.Invention Patent: "DEVICE FOR INTRACORNEAN IMPLANT AND PROCESS FOR TREATING CORONAL DEFORMITIES" <D>. The present invention relates to an intracorneal implant device comprising a solid or gelatinous body consisting of a biocompatible polymer having at least one outer surface, said outer surface having, applied over it as a coating, a material reactive to the biocompatible polymer and covalently attached to the body of the implant device, said reactive material having chemical characteristics similar to the fundamental substance of the cornea. The device of the invention is suitable for the treatment of corneal deformities such as keratoconus, irregular astigmatisms after corneal transplants and Lasik and PRK corneal refractive surgeries, myopia and other ametropias.
