Abstract

MéTODO DE MEDIçãO DE LENTES DIFRATIVAS. A presente invenção se refere a um método de medição das propriedades áticas de lentes oftálmicas multifocais. A luz colimada é passada através de uma lente oftálmica e sobre uma estrutura de lentículas. A luz que sai da estrutura de lentícula é detectada por um sensor. Os pontos manchados e/ou pontos duplos podem representar zonas de dif ração de uma frente de onda. O centróide de um ponto ou o mais brilhante de dois pontos pode ser usado para determinar a posição lateral do ponto. Cálculos teóricos, medições de laboratório, medições clínicas e pontos de imagem experimental podem ser gerados, comparados e checados para determinar a lente equivalente monofocal. Uma MTF pode ser usada para avaliar e comparar a lente difrativa e uma lente equivalente monofocal.
