Abstract[English]
The invention provides a method for producing embedded diffractive contact lenses involving use of a mold set in two-curing steps. The mold set consists of three mold halves, one of which is used twice, the first time for molding a diffractive insert and the second time for an embedded contact lens with the molded diffractive insert embedded therein. The twice-used mold half has been treated with a corona plasma or a vacuum UV in a central circular area having a diameter equal to or smaller than the diameter of the insert to ensure that the molded insert consistently adheres to the twice-used mold half, even though the other mating insert mold half for molding the diffractive insert has a great tendency to bind strongly the molded insert due to the diffractive structure on its molding surface.[French]
L'invention concerne un procédé de production de lentilles de contact diffractives intégrées impliquant l'utilisation d'un ensemble de moules dans deux étapes de durcissement. L'ensemble de moules est constitué de trois moitiés de moule, dont l'une est utilisée deux fois, la première fois pour mouler un insert diffractif et la seconde fois pour une lentille de contact intégrée dans laquelle est intégré l'insert diffractif moulé. La moitié de moule utilisée deux fois est traitée avec un plasma corona ou un UV sous vide dans une zone centrale circulaire ayant un diamètre inférieur ou égal au diamètre de l'insert pour garantir que l'insert moulé adhère de manière constante à la moitié de moule utilisée deux fois, même si l'autre moitié correspondante de moule d'insert pour mouler l'insert diffractif a une grande tendance à se lier fortement à l'insert moulé en raison de la structure diffractive sur sa surface de moulage.
