Contour form control

A method for forming an ophthalmic Lens comprising:

• positioning a substrate having an optical quality surface within a first volume of Fluent Lens Reactive Media,
• obtaining a Contour Forming device including a DMD having an array of selectively controllable micro-mirrors;
• creating a first DMD Show based upon a target Lens Design, said first DMD Show including a time-based sequence for selectively controlling said array of micro-mirrors of said DMD;
• using the first DMD Show to control the DMD to selectively transmit actinic radiation through the substrate to thereby polymerize portions of the first volume of Fluent Lens Reactive Media on a voxel by voxel basis to from a first Lens Precursor;
• further processing the first Lens Precursor to form a first ophthalmic Lens;
• comparing the first ophthalmic Lens to the target Lens Design;
• creating a second DMD Show by modifying the first DMD Show using a Convergence process based on information obtained from said comparing step;
• positioning said substrate within a second volume of Fluent Lens Reactive Media;
• using the second DMD Show to control the DMD to selectively transmit actinic radiation through the substrate to thereby polymerize portions of the second volume of Fluent Lens Reactive Media on a voxel by voxel basis to form a second Lens Precursor,
• further processing the second Lens Precursor to form a second ophthalmic Lens;
• wherein the second ophthalmic Lens more closely approximates the target Lens Design than said first ophthalmic Lens.
