Methods and systems for determining control inputs to a manufacturing apparatus to manufacture a product are described. A processor may receive model data including initial state data indicating an initial state of an input material, a set of model control inputs, and target measurement data associated with a target product. The processor may learn a causal predictive model based on the target data. Each state of the causal predictive model may be based on an application of the model control inputs on a previous state of the causal predictive model. The processor may compare a final state of the causal predictive model with the target measurement data to determine a difference. The processor may determine, based on the difference, a set of control inputs to be assigned to one or more controls. The one or more controls may define a design of the manufacturing process of an end product.

Free-form production based on causal predictive models

A contact lens having a lens edge defining an outer periphery of the contact lens, an optic zone positioned within the lens edge designed to provide corrective vision for a patient, a Lens Center having a vertical axis and a horizontal axis passing therethrough, and first and second fiducial indicators present at first and second different locations around the lens edge. The first and second fiducial indicators each include at least one recess into or at least one projection extending outwardly from the lens edge and are different from one another.

Lens edge features for determing lens placement and alignment

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.

Methods for incorporating lens features and lenses having such features

This invention describes methods and apparatus for implementing a Convergence Process to Converge a Lens Design wherein a previous DMD Show may be modified for a subsequent Iteration. In preferred embodiments, an Iterative Loop may be initiated during a Convergence Process wherein one or more of various: techniques, modalities, and thickness correction methods may be implemented.

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.

This invention provides for the fabrication of ophthalmic lenses via the utilization of DMD shows and/or DMD files. More specifically, the use of the DMD shows and/or DMD files to generate lens precursor designs comprising described features to form part of a substructure for the fluid reactive media portion of the lens precursor and wherein the lens precursor can generate particular ophthalmic lens designs in a free-form manner using methods described herein.

Lens precursor with features for the fabrication of an ophthalmic lens

A system and method for identifying a custom contact lens for a patient. The method includes receiving as input results from a bare eye examination of a patient including at least a measured sphere power; receiving as input a target or actual measured sphere power of a selected fitting lens; receiving as input results of an over-refraction examination of a patient wearing the fitting lens, wherein the results of the over-refraction examination include at least a measured sphere power; calculating the power delivered by the fitting lens on the patient's eye based on input received from the bare eye examination and over-refraction examinations; calculating an Effectiveness Ratio using the calculated power delivered by the fitting lens and the target or actual measured sphere power of the fitting lens; and calculating a custom lens power for the patient using the Effectiveness Ratio and measured sphere power from the bare eye examination.

The present invention discloses a translating multifocal contact lens including one or both of multiple Optic Zones and a lower-lid contact surface, and method steps and apparatus for implementing the same. In preferred embodiments, a translating multifocal lens may be Free-formed comprising a lower-lid contact surface capable of limiting the amount of translation of a lens across a surface of an eye when an eye changes from one Optic Zone to another.

Method and apparatus of forming a translating multifocal contact lens having a lower-lid contact surface

The present invention discloses a translating multifocal contact Lens including one or both of a lower-lid contact surface and an under-lid support structure. More specifically, a translating multifocal contact Lens whereby a lower-lid contact surface may include multiple geometric variations and Blend Zones, and an under-lid support structure that may be designed based upon one or more various techniques including one or more of a function-driven technique, a uniform axial thickness technique, a uniform radial thickness technique, and a MES technique.

An apparatus and method for selecting a lens that accounts for Decentration and/or Rotation Errors. The method includes obtaining results of a first wavefront exam on a patient, including a wavefront map and Zernike polynomials, selecting a first lens that improves vision, obtaining the results of a second wavefront exam including a wavefront map and Zernike polynomials, calculating the Decentration and/or Rotation Errors of the selected lens by calculating a difference between the Zernike polynomails, and selecting a second lens that better corrects accounts for the calculated Decentration and/or Rotation Errors.
