Abstract

Patente de Invenção: <B>"LENTE DE CONTATO TóRICA COM COMPENSAçãO DE DESLOCAMENTO DE EIXO E MéTODO PARA FABRICAçãO DA MESMA"<D>. Uma lente de contato e um método e aparelho para fabricar uma lente de contato que tem áreas de espessuras diferentes, a lente de contato sendo compensada para o encolhimento diferencial durante o processo de fabricação. O deslocamento angular do eixo geométrico cilíndrico devido ao encolhimento diferencial é compensado introduzindo um deslocamento igual e oposto durante o processo de fabricação. O deslocamento de eixo geométrico cilíndrico causado por um processo de fabricação particular é determinado experimentalmente, isto é, para cada eixo geométrico cilíndrico pretendido, o deslocamento correspondente (em termos de graus de rotação) é determinado. A compensação da lente é implementada ajustando o processo de fabricação de modo que quando curada a lente corresponde à lente prescrita, desejada, sem nenhum deslocamento de eixo geométrico.
