Abstract:
1. A method of delensing a polymerized contact lens product from a contact lens mold member, comprising: demolding a contact lens mold to separate a first contact lens mold member and a second contact lens mold member from each other, such that a polymerized contact lens product remains attached to or in contact with one of the first contact lens mold member or the second contact lens mold member, the first contact lens mold member having a concave surface defining an anterior lens surface and the second contact lens mold member having a convex surface defining a posterior lens surface; compressing a portion of the one of the first contact lens mold member or the second contact lens mold member having the polymerized contact lens product attached to or in contact therewith; and directing a gas toward the polymerized contact lens product to facilitate separation of the polymerized contact lens product from the portion of the one of the first contact lens mold member or the second contact lens mold member; wherein the compressing step and directing step occur simultaneously, and the polymerized contact lens product is a pre-extracted silicone hydrogel contact lens.
