Abstract
éthode améliorée pour la fabrication de lentilles cornéennes dans laquelle un mélange monomère ou comonomère est placé dans une cavité de moule et soumis à des conditions de polymérisation afin de façonner une forme polymérisée prédéterminée. L'amélioration consiste en l'inclusion d'un démoulant dans le mélange monomère, lequel démoulant constitue moins d'environ trois pour cent en poids dudit mélange monomère et est choisi parmi un mélange de polymères hydrophiles avec des composés lipophiles.
