A method for cleaning contact lenses employs a composition that includes tromethamine in an amount effective to reduce the amount of denatured protein on the contact lens, thus rendering the contact lenses easier to clean. Additionally, by soaking contact lenses in the composition prior to inserting the lens on the eye, the compositions provide a prophylactic effect in preventing protein denaturation while the contact lens is worn.
Cette invention concerne un procédé de nettoyage pour lentilles de contact au moyen d'une composition comprenant de la trométhamine en dose efficace pour réduire la quantité de protéine dénaturée sur la lentille de contact, ce qui a pour effet de faciliter le nettoyage. Par ailleurs, l'immersion de la lentille de contact dans la composition préalablement à sa mise en place sur l'oeil a un effet prophylactique qui empêche une dénaturation de protéines pendant le port de la lentille de contact.
