Title
(EN) VARIABLE TRANSMISSIVITY ANNULAR MASK LENS FOR THE TREATMENT OF OPTICAL ABERRATIONS
(FR) LENTILLE DE CONTACT A MASQUE ANNULAIRE A TRANSMISSIVITE VARIABLE CONVENANT AU TRAITEMENT D'ABERRATIONS OPTIQUES
Abstract
(EN)
An annular mask lens for the treatment of optical aberrations such as but not limited to night myopia, spherical aberration, aniridia, keratoconus, corneal scarring, penetrating keratoplasty, and post refractive surgery complication. The lens has an annular mask having an aperture larger than conventional pinhole contact lens. The aperture having a 'soft' inside edge and which mask has a gradually increasing transmissivity radially towards the outer edge of the mask.
(FR)
La présente invention concerne une lentille de contact à masque annulaire convenant au traitement d'aberrations optiques telles que notamment la myopie scotopique, l'aberration sphérique, l'aniridie, le kératocône, les taies de la cornée, les séquelles de kératoplastie transfixiante, les séquelles de chirurgie réfractive. La lentille comporte un masque annulaire présentant une ouverture supérieure à celle des lentilles de contact conventionnelles du type trou d'épingle. En l'occurrence, l'ouverture présente un bord intérieur 'doux', la transmissivité du masque augmentant graduellement radialement vers le bord externe du masque.
