    摘要： The present invention includes without limitation a process for separating a hydrogel contact lens from at least one mold half selected from the group comprising the anterior half and the posterior half of a contact lens. The process comprising the step of contacting either the contact lens or the one half with a maximum of about 1000 μl of a super-cooled fluid to create a temperature differential between the contact lens and the one half.

    摘要： The present invention is a process for extracting pre-polymer from a polymer lens. The process comprises the step of contacting the lens with a super-cooled solvent for a period of time to increase the modulus of the contact lens. Thereafter the contact lens undergoes additional dry processing steps. By way of example, the dry processing steps include but are not limited to surface treatment, lens coating and polishing and/or edging of the contact lens.

    摘要： Method and apparatus for preparing a silicone hydrogel lens including heating a cast lens to drive off an organic diluent by moving the cast lens continuously through heating and cooling zones to provide a first-in-first-out handling system. The zones are either horizontally or vertically arranged. An apparatus embodiment of a vertical heating zone includes outer and inner concentric shells arranged in a heating chamber. One of the shells rotates about a vertical axis relative to the other. The outer shell has a spiral rail extending into the space between the outer and inner shells and the inner shell has a plurality of vertical ribs spaced about its periphery. A lens carrier placed on the rail is engaged and driven along the spiral rail by one of the ribs responsive to the relative motion between the outer and inner shells.
