Methods for manufacturing an ophthalmic lens with an insert (521) using voxel-based lithography techniques, wherein at least a portion of one surface may be free-formed from a reactive mixture (531) are set forth herein. An ophthalmic lens precursor may be formed on a substrate with an arcuate optical quality surface via a source (542) 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.
