Abstract

La presente invencion proporciona generalmente lentes oftálmicas multifocales, por ej., lentes intraoculares multifocales, que emplean una region refractiva central para proporcionar un poder de focalizacion refractivo y una region difractiva para proporcionar dos poderes de focalizacion difractivos. En muchos casos, el poder de focalizacion refractivo proporcionado por la region central de la lente corresponde a un poder de focalizacion de lejos que es sustancialmente igual a uno de los poderes de focalizacion difractivos mientras que el otro poder difractivo corresponde a un poder de focalizacion de cerca. Como tales, en muchos casos, las propiedades de focalizacion de las lentes son dominadas por la capacidad de foco de lejos, especialmente para tamanos de pupila pequenos.
