Abstract

sistema para controlar um feixe laser é descrito um sistema e método para alterar a forma de uma lâmina de material transparente (por exemplo, a córnea de um olho), à medida que ela é submetida a um diferencial de pressão transversal, que exige uma unidade laser controlada por computador. de acordo com parâmetros de entrada especificados, o computador direciona a unidade laser para realizar liob em superfícies predeterminadas na lâmina. isto enfraquece o material para um remodelamento desejado da lâmina em resposta ao diferencial de pressão. com relação a um eixo perpendicular que é definido pela lâmina, superfícies paralelas ao eixo (por exemplo, superfícies cilíndricas) são separadas umas das outras por cerca de duzentos mícrons. para superfícies perpendiculares ao eixo, a separação é cerca de dez mícrons. de qualquer maneira, os cortes resultantes de liob têm apenas cerca de dois mícrons de espessura.
