摘要： The present invention provides a method for producing an ophthalmic device by means of stereolithography. The method comprises the steps of: depositing (i) an essentially solvent-free liquid or melt of a device-forming material, or (ii) a solution of said device-forming material, into a container wherein said device-forming material is crosslinkable or polymerizable by actinic radiation; irradiating said device forming material with one or more activation energy beams to obtain a cured layer of polymerized or crosslinked device-forming material; irradiating said device-forming material with said one or more activation energy beams to obtain a cured layer on top of a previously cured layer; and repeating step (c) to obtain additional cured layers until said ophthalmic device is created integrally, wherein each of cured layers corresponds to a pertinent slice of said ophthalmic device.
