description | The invention relates to a novel ophthalmic lens designed to extend the depth of focus for a patient using the lens. The lens comprises an optic having an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface includes a first zone extending from the optical axis to a first radial boundary and a second zone extending from the first radial boundary to the edge of the optic. The first zone comprises a surface having the characteristics of an odd asphere axicon, while the second zone comprises a surface having the characteristics of an even asphere. If the ophthalmic lens is intraocular, haptics will be attached to the optic to hold the lens in place after insertion into a human ocular capsular bag.
L'invention concerne une nouvelle lentille ophtalmique conçue pour augmenter la profondeur de focalisation d'un patient utilisant la lentille. La lentille comprend une optique dotée d'une surface antérieure, d'une surface postérieure et d'un axe optique. Au moins l'une des surfaces antérieures et postérieures comprend une première région s'étendant de l'axe optique à une première limite radiale et une seconde région s'étendant de la première limite radiale au bord de l'optique. La première région comprend une surface présentant les caractéristiques d'un axone à surface asphérique impair, tandis que la seconde région comprend une surface présentant les caractéristiques d'un axone à surface asphérique paire. Si la lentille ophtalmique est intraoculaire, des haptiques seront fixés à l'optique pour maintenir la lentille en place après son insertion dans un sac capsulaire oculaire humain. |
