Abstract

Patente de Invenção: <B>"MéTODO E APARELHO PARA CIRURGIA OFTALMOLóGICA POR FEIXE DE LASER"<D>. Um método para cirurgia oftalmológica por feixe de laser para a ablação de uma córnea (16) do olho de um paciente inclui as etapas de gerar um feixe de laser (12) e direcionar o feixe de laser gerado sobre um aparelho de varredura (13) e varrer o feixe de laser (12) em um padrão de varredura aleatório com um sinal de padrão de varredura aleatório gerado na superfície da córnea (16) de um paciente para retirar a superfície da córnea do olho de um paciente. Um computador (17) gera o sinal de controle de feixe de laser padrão aleatório que controla o aparelho de varredura (13) para varrer no padrão de varredura aleatório sobre a córnea (16) e inclui a seleção de uma base de dados de pontos de varredura não-aleatórios para varrer o feixe de laser sobre a córnea (16) do olho de um paciente, e em seguida aleatoriamente selecionar os pontos de varredura não-aleatórios para a varredura aleatória de pontos de varredura predeterminados. Um aparelho para cirurgia oftalmológica por laser (10) é provido, o qual inclui um laser (11) para a geração de um feixe de laser (12) junto com um aparelho de varredura (13) posicionado para receber o feixe de laser (12) e produzir um padrão de varredura predeterminado sobre a córnea (16) de um olho. Um computador (17) é usado para gerar um sinal de padrão de varredura aleatório e é conectado ao aparelho de varredura (13) para o controle do aparelho de varredura em um padrão de feixe de varredura sobreposto aleatório sobre uma área predeterminada.
