Abstract

Una lente corneal bifocal que es de sección transversal cóncavo-convexa, que es de un solo material que tiene un índice de refracción uniforme; que tiene una superficie de base interior central cóncava para ajustarse a la córnea del usuario, una superficie segmentaria convexa de visión cercana que define un segmento inferior de visión cercana; una superficie segmentaria convexa de visión lejana que define un segmento superior de visión lejana está dispuesta por encima de dicho segmento de visión cercana, caracterizada porque dicha lente está delimitada por una zona de límite de grueso que aumenta radialmente hacia fuera, definiendo dicha zona de límite entrante con los segmentos adyacentes de visión cercana y visión lejana.
