Abstract

"REFRAçãO MANIFESTA OBJETIVA". Um método para prover uma refração manifesta objetiva de um olho de paciente que inclui obtenção de pelo menos informação de aberração de frente de onda de Zernike de quarta ordem, adaptação de um polinómio apenas de segunda ordem a pelo menos dados de quarta ordem, e uso desta informação para predizer a refração manifesta de paciente com uma abordagem acurada da refração manifesta subjetiva de paciente. Um método também é descrito para prescrever uma correção de visão acurada baseada na refração manifesta objetiva. Uma exibição de acordo com a invenção inclui aberrações de frente de onda de ordem mais alta, aberrações de frente de onda de ordem mais baixa, índice numérico de refração manifesta prevista, e imagens de avaliações qualitativas de uma qualidade de visão de paciente. Um dispositivo para obter uma refração manifesta objetiva é descrito.
