Abstract

Un método para moldear lentes de contacto tóricas que tienen superficies ópticas anterior y posterior opuestas, incluyendo además dichas lentes tóricas un eje tórico y un eje de lastre formados en dichas superficies ópticas opuestas de las mismas, respectivamente, incluyendo establecer automática y selectivamente cualquiera de una pluralidad de desviaciones axiales predeterminadas, entre 0 grados y 180 grados, entre dicho eje tórico y dicho eje de lastre de dichas lentes, donde las lentes de contacto tóricas se forman en un molde respectivo incluyendo secciones de molde anterior (12) y posterior (14) que tienen superficies anterior y posterior de molde, respectivamente, formado dicho eje tórico en una de dichas superficies anterior y posterior de molde, y formado dicho eje de lastre en la otra de dichas superficies anterior y posterior de molde, formando dichas superficies anterior y posterior de molde dicho superficies ópticas anterior y posterior de dichas lentes, respectivamente, e incluyendo una característica detectable (15'', 19'') en cada una de dichas secciones de molde anterior y posterior en una posición angular predeterminada con respecto a dichos ejes tórico y de lastre de las mismas, respectivamente.
