An ophthalmic device is formed by additive fabrication, the optical device having optical surface with a surface roughness on the order of less than 10 microns. A method is provided for making an ophthalmic device including an optical surface having a surface roughness of less than 10 microns by depositing on a stage in a first relative position a first lamina of particulates having a size less than 10 microns and in select configurations less than two microns and certain configurations less than one micron, and, synergistically stimulating the first lamina of particulates to form a first solidified layer.

A mold assembly for the manufacture of at least one ophthalmic device used in or on the eye is disclosed. The mold assembly includes a mateable pair of mold parts wherein at least one of the mold parts comprises at least an oxygen-absorbing mold material and an oxygen scavenger composition containing (i) an oxygen scavenging polymer comprising a polymer backbone and one or more substituted or unsubstituted cyclic olefinic groups covalently linked to the polymer backbone; and (ii) an oxygen scavenging catalytic amount of a transition metal catalyst.

Molds for production of ophthalmic devices

An apparatus for releasing a molded lens from a deformable mold includes a shear ring for temporarily retaining an annular portion of the deformable mold outside a periphery of the lens and a plunger for deforming an annular section of the deformable mold within the periphery of the lens. The apparatus can be employed to release a non-hydrated hydrogel lens from a deformable mold section.

Intraocular lenses or contact lensesare placed on a lower spindleand held there by a vacuum in conduit. Noble and reactive gasesare introduced and a voltage is applied across upper spindleand lower spindleto plasma treat one surface of the lens. The lens is transferred to the other spindle and the process is repeated.
