Abstract

Patente de Invenção:<B>"MéTODO E APARELHO PARA O AJUSTE DE CURVATURA CORNEANA USANDO UM ANEL CORNEANO COM MATERIAL BIOCOMPATìVEL REMOVìVEL"<D>. Um dispositivo intra-estromal ajustável, adaptado para a implantação na córnea e formado de um invólucro oco flexível (30a) que é implantável dentro da córnea em uma relação de envolvimento na zona ótica central da córnea. O implante é cheio em uma quantidade predeterminada com uma quantidade selecionada de material sólido biocompatível de diversas formas, tal como um anel sólido (38) ou fios compostos de materiais poliméricos flexíveis de diversos formatos e comprimento, ou de modo alternativo, um fluído tal como salina ou gel nos compartimentos (117) do invólucro (107) que podem ser seletivamente perfurados. O material de enchimento biocompatível é estrategicamente localizado dentro do invólucro flexível de modo a alterar suas dimensões de espessura ou diâmetro e, desta maneira, ajustar a curvatura corneana para a correção de um erro refrativo. Outros ajustes do implante podem ser feitos em um momento pós-operatório após a implantação por meio da retirada seleiva do material de enchimento biocompatível, ou da adição de um material novo ao dispositivo.Invention Patent: <B> "METHOD AND APPARATUS FOR CORRECT CURVE ADJUSTMENT USING A CORNEAN RING WITH BIOCOMPATIBLE REMOVABLE MATERIAL" <D>. An adjustable intra-stromal device, adapted for implantation in the cornea and formed of a flexible hollow shell (30a) that is implantable within the cornea in a wrapping relationship in the central optical zone of the cornea. The implant is filled in a predetermined amount with a selected amount of solid biocompatible material in various ways, such as a solid ring (38) or wires composed of flexible polymeric materials of varying shapes and length, or alternatively, a fluid such as saline or gel in the compartments (117) of the housing (107) which can be selectively perforated. The biocompatible filling material is strategically located inside the flexible casing in order to change its thickness or diameter dimensions and, thus, adjust the corneal curvature to correct a refractive error. Other adjustments of the implant can be made in a post-operative moment after implantation through the selective removal of the biocompatible filling material, or the addition of a new material to the device.
