Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA A ABERROMETRIA ONLINE NA CORREçãO REFRATIVA DE OLHOS"<D>. A invenção refere-se a um processo e a um dispositivo para a correção completa de defeitos de visão no olho humano. Foram indicadas combinações de métodos de medição e processamento, que quando aplicados de acordo com a invenção tornam possível corrigir completamente defeitos de visão no olho humano. São usados métodos de medição que podem escanear precisamente a superfície da córnea e também registrar outros defeitos de imagem na trajetória de luz até a retina. Os resultados da referida medição determinados com auxílio de computador, quando combinados com o cálculo da correção ideal das lentes oculares (por exemplo, depois de operação de catarata) ou superfícies de correção ideal da córnea, abrem a possibilidade de manufaturar uma lente específica para o paciente e/ou obter a correção ideal da córnea usando, de preferência, um sistema a laser apoiado na topografia de spot-scanning-excimer.
