Methods for formation of an ophthalmic lens with an insert utilizing voxel-based lithography techniques
Methods for manufacturing an ophthalmic lens with an insert using voxel-based lithography techniques, wherein at least a portion of one surface may be free-formed from a reactive mixture are set forth herein. An ophthalmic lens precursor may be formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of reactive mixture, wherein the control may be on a voxel by voxel basis.
APPARATUS FOR FORMATION OF AN OPHTHALMIC LENS PRECURSOR AND LENS
This invention discloses apparatus for generating an ophthalmic lens with at least a portion of one surface free-formed from a Reactive Mixture. In some embodiments, an ophthalmic lens is formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of Reactive Mixture.
Method and Apparatus for Spatially Locating Lens Components on a Lens Precursor
This invention provides for Spatial Placement of Lens Components by Spatially Polymerizing portions of Fluent Lens Reactive Media using one or more controlled projections of actinic radiation to a Lens Precursor device. More specifically, the Lens Components Spatially Placed can include one or more of: electrical components, pigment particles, coatings, and active agents. The control of the actinic radiation can include the use of a voxel based lithography method using a digital micromirror device, a laser, or the use of a photomask.
APPARATUS AND METHODS FOR CONTROLLING AXIAL GROWTH WITH AN OCULAR LENS
One embodiment of an ocular lens includes a lens body configured to contact an eye where the lens body has an optic zone shaped to direct central light towards a central focal point of a central region of a retina of the eye. At least one optic feature of the lens body has a characteristic that directs peripheral light off axis into the eye away from the central region of the retina. Another embodiment of an ocular lens has at least one isolated feature of the lens body that has a characteristic of directing peripheral light off axis into the eye away from the central region of the retina. Methods of making contact lenses include forming the features during the manufacturing process.
Apparatus for formation of an ophthalmic lens precursor and lens

METHODS FOR INCORPORATING LENS FEATURES AND LENSES HAVING SUCH FEATURES
A Free-form contact lens and method of making the same. The lens includes a posterior optical quality surface having a concave shape, an opposing anterior surface having a convex shape both of which join at a lens edge that defines an outer periphery of the contact lens, and at least a first lens feature having a predetermined shape and made of a first polymerized Reactive Mixture. The remainder of the lens is made of a second polymerized Reactive Mixture that is different than the first polymerized Reactive Mixture, and that is covalently bonded thereto.
