Lens precursor with features for the fabrication of an ophthalmic lens

摘要

A method of designing a lens precursor form (105B) comprising defining a lens precursor form design, the design including a lens edge (HOB) that defines the outer perimeter of the lens precursor form; a plurality of lens features selected from the group consisting of a lens edge feature that is present along at least part of the lens edge, an optic zone (125B) that is present within the outer perimeter of the lens precursor form, a stabilization zone feature (115B) that is present within the outer perimeter of the lens precursor form, and a volumator feature (120B) that is present within the outer perimeter of the lens precursor form between at least two of the said plurality of lens features; wherein each of the lens features is parametrically defined and wherein the parameters defining at least one lens feature are selected based at least in part upon the parameters defining one or more adjacent lens features and a desired lens shape.
