Abstract
An ophthalmic device is formed by additive fabrication, the optical device having an 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.
Claims19
A method of making an ophthalmic device including an optical surface the method comprising:
- a) depositing on a stage in a first relative position a first lamina formed of a plurality of ophthalmic device forming droplets having a size less than approximately ten microns, and the plurality of droplets selected to form a portion of the optical surface of the ophthalmic device in response to synergistic stimulation;
- and,
- b) synergistically stimulating the first lamina of droplets to form a first solidified layer, a portion of the first lamina forming a portion of the optical surface.
A method of forming an ophthalmic device suitable for placement in or on an eye, the method comprising depositing by additive fabrication a plurality of bonded laminae, each lamina formed of a plurality droplets selected to form a portion of the ophthalmic device suitable for placement in or on an eye, in response to synergistic stimulation, at least a portion of one lamina defining a portion of an optical surface of the ophthalmic device.
A method of making an ophthalmic device including an optical surface, the method comprising;
- a) depositing on a stage in a first relative position a first lamina formed of a plurality of droplets containing polymerizable hydrophilic, siloxy-containing monomonomeric liquid, the droplets having a size less than approximately ten microns, and the plurality of droplets selected to form a portion of the ophthalmic device in response to synergistic stimulation;
- and,
- b) synergistically stimulating the first lamina of droplets to form a first solidified layer, the in solidified layer forming a portion of the ophthalmic device.
