ARTIFICIAL LENS, IN PARTICULAR A CONTACT OR INTRAOCULAR LENS, FOR CORRECTING PRESBYOPIA, POSSIBLY ASSOCIATED WITH OTHER VISUAL DEFECTS, AND RELATIVE PRODUCTION METHOD |
摘要 |
An artificial lens (1) (contact lens or intraocular lens) for correcting presbyopia, possibly associated with other refractive defects, has at least one region (5) having a fourth-order aberration, in particular a spherical aberration, of more than zero and less than 3.5 gm, and possibly associated with a basic vertex power for correcting refractive defects, and with fourth- and higher-order aberrations for improving vision acuity. The lens is produced by ablating a surface of a base body of the lens by means of an appropriately controlled laser device, and according to a given photoablative pattern to induce the desired aberration. |
