Abstract

Una lente de contacto y un método para fabricar una lente de contacto con áreas de diferente espesor, lente de contacto que está compensada por elencogimiento diferencial producido durante el proceso de fabricacion. La toricidad inadmisible inducidapor el encogimiento diferencial provocado por undeterminado proceso de fabricacion se determina experimentalmente, tanto en términos de posicion angular como de potencia. La compensacion de la lente seobtiene confiriendo una potencia igual y opuestaa la toricidad perjudicial inducida por el proceso de fabricacion.
