    • An intraocular lens system for implantation in the eye to modify the lens system of the eye comprising the cornea and the natural or existing artificial lens in the eye, and a method for using the same. The system and method comprises a lens having a high minus portion, adapted to be implanted in the eye to create a lens system that functions as a teledioptic lens system which, when used without an external lens, provides unmagnified and peripherally unrestricted vision and which, when used with an external lens, provides magnified and peripherally restricted vision to correct for macular degeneration. The lens can be attached to the iris, to a portion of the iris that was removed by iridectomy, or can be implanted in the cornea. The lens can also include a plus portion that is surrounded by the high minus portion. The high minus portion is preferably about one to about three millimeters in diameter, and can have an outer perimeter with no surrounding material or can be surrounded by a plus, minus or toric lens.

    • Un système de grandissement d'image rétinienne comprend un implant intraoculaire (14) et une lentille (16) externe à l'oeil. L'implant a une partie périphérique (24) et une partie centrale (22) de puissance négative. La lentille (16) a une puissance positive et est destinée à être disposée à l'extérieur de l'oeil, typiquement dans une monture de lunettes. La lentille (16) et l'implant (14) produisent dans le fond de l'oeil d'un utilisateur standard une image agrandie d'un objet. Pour une pupille de 1,5 mm de diamètre, tout objet ponctuel dans un champ objet de lecture produit dans le fond de l'oeil une tache image d'une taille comprise entre 20 à 50 µm. L'invention permet d'obtenir un champ large en lecture, au prix d'une dégradation des performances du système sur l'axe, acceptable compte tenu de l'acuité des patients traités. En outre, elle fournit un système dont les performances varient peu lorsque la position de la lentille s'écarte de la position nominale.

    • An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics.
    • 一种容纳(可重新聚焦的)透镜系统,其主体在组装时包括具有沿着光轴顺序设置的第一和第二光学部分的第一和第二单独的小透镜。 系统的光功率调节的改变是通过响应于施加到小透镜的力并改变为轴向力而改变小透镜之间的平坦的接触面积来实现的。 在特定情况下,第一和第二小透镜形成人工晶状体(IOL),并且具有各自的触觉部分,这是由于相对于另一个小透镜旋转而使第一和第二小透镜在轴向接触的结果互锁的。 通过改变接合面,然后响应于由触觉件的互锁端部之间的距离的变化引起的径向力,并通过互锁的触觉件转移到光学部件。
