Abstract

Un método para proporcionar un lente de contacto (20) para un paciente. De acuerdo con este método, se selecciona una preforma optica (20), y se determina una posicion de reposo de la preforma optica (20) en el ojo del paciente. También se localiza una característica optica (11) en el ojo del paciente. Entonces, una posicion de referencia (12) se localiza sobre la superficie de la preformaoptica (20) coincidente con la característica optica (11) en el ojo del paciente, cuando la preforma optica (20) está en la posicion de reposo. Finalmente, se proporciona la modificacion optica en la preforma optica (20) en una ubicacion apoyada sobre la posicion de referencia (12) en la preforma optica (20).
