Abstract

See full text

Methods and apparatus which are utilized for the production of ophthalmic lenses, and more particularly, a method for the removal or demolding of molded ophthalmic contact lenses from the individual molds in which they are produced. The apparatus implements the demolding of such ophthalmic lenses, the latter of which may consist of suitable hydrogel contact lenses or other types of high-precision ophthalmic lenses; for example, such as intraocular contact lenses. Mechanical prying apart of such mating mold half portions, and to facilitate this procedure at a reduced application of force, while concurrently potentially preventing or at least appreciably ameliorating the extent of any possible sticking together of the mold half portions is effected in that mechanical leverage applied to the upper mold half portion, in addition to the application of the heating action thereto.
