Title (EN) BIREFRINGENT INTRAOCULAR LENS
(FR) LENTILLE INTRAOCULAIRE BIRÉFRINGENTE
Abstract:
(EN) A multifocal intraocular lens (MF-IOL) includes a circularly birefringent material with a right- handed index of refraction nR for a light with a right-handed polarization, and a left-handed index of refraction nI, for a light with a left-handed polarization; and haptics, to position the multifocal intraocular lens inside a capsule of an eye; wherein the multifocal intraocular lens has a right- handed optical power DR for the light with the right-handed polarization, and a left-handed optical power DL for the light with the left-handed polarization, wherein DI/DR=(nL-1)(nR-1). Some variations of the MF-IOL include stimulus-orientable optically anisotropic constituents. Some classes of the MF-IOL include a self-assembling optically anisotropic compound. A corresponding method of a making a MF-IOL is comprising providing stimulus-orientable optically anisotropic constituents as part of an intraocular lens; orienting the optically anisotropic constituents by applying a non-stretching stimulus; and locking-in the oriented optically anisotropic constituents to form the multifocal intraocular lens.
(FR) Lentille intraoculaire multifocale (MF-IOL) comprenant un matériau circulairement biréfringent ayant un indice de réfraction droit nR pour une lumière ayant une polarisation droite, et un indice de réfraction gauche nI, pour une lumière ayant une polarisation gauche; et des haptiques, pour positionner la lentille intraoculaire multifocale à l'intérieur d'une capsule d'un œil; la lentille intraoculaire multifocale ayant une puissance optique droite DR pour la lumière ayant la polarisation à droite, et une puissance optique gauche DL pour la lumière ayant la polarisation à gauche, DI/DR=(nL-1)(nR-1). Certaines variantes de la MF-IOL comprennent des constituants optiquement anisotropes orientables par stimulus. Certaines classes de la MF-IOL comprennent un composé optiquement anisotrope à auto-assemblage. Un procédé correspondant de fabrication d'une MF-IOL consiste à fournir des constituants optiquement anisotropes orientables par stimulus en tant que partie d'une lentille intraoculaire; à orienter les constituants optiquement anisotropes par application d'un stimulus de non-étirement; et à verrouiller-dans les constituants optiquement anisotropes orientés pour former la lentille intraoculaire multifocale.
