Abstract: An apparatus and method for releasing a lens molded in a cavity between posterior and anterior mold sections and adhered thereto. A post is configured to support a flange of the posterior section while the anterior section remains spaced from the post. Posterior section is compressed between a pin applied to an outer concave surface of the posterior section and the post, thereby initially releasing peripheral regions of the posterior section and subsequently the remaining portions thereof. Upon separation, the anterior section together with the lens drops onto the post so that its outer convex surface rests on the post. A collar unit with gas channels presses against a flange of the anterior section while blowing jets of gas towards an interface between a “monomer” ring formed around the lens. In this manner, initially the “monomer” ring and then peripheral regions of the lens are separated from the anterior section.

Abstract: An apparatus and method for releasing a lens moulded in a cavity between posterior (21) and anterior mould (22) sections and adhered thereto. A post (30) is configured to support a flange (20) of the posterior section whilst the anterior section remains spaced from the post. Posterior section is compressed between a pin (40) applied to, an outer concave surface (29a) of the posterior section and the post, thereby initially releasing peripheral regions of the posterior section and subsequently the remaining portions thereof. Upon separation, the anterior section together with the lens (10) drops onto the post so that its outer convex surface (29a) rests on the post. A collar unit (50) with gas channels (53) presses against a flange (200) of the anterior section whilst blowing jets of gas towards an interface between a “monomer” ring (11) formed around the lens. In this manner, initially the “monomer” ring and then peripheral regions of the lens are separated from the anterior section.

Abstract: A method of treating an ophthalmic lens in a package involves: placing the lens and an aqueous solution in a recess of package, the solution including an organic surface treatment agent that attaches to anterior and posterior surfaces of the lens; and sealing the recess of the package with lidstock and sterilizing the package contents. The bottom of the recess includes grooves.
