METHOD OF MANUFACTURING A CONTACT LENS

摘要

Contact lens molds and systems and methods for producing contact lens molds are described. The contact lens mold sections (10) include two optical quality surfaces (16,17), a flange (18) circumscribing at least a portion of the two optical quality surfaces, and an elongate member (24) extending from the flange. Two mold sections (10, 10') can contact one another to form a mold assembly (26) having a contact lens shaped cavity. The mold sections (10, 10') are structured to form a contact lens having an edge that does not require further physical modification before placement on an eye. Systems and methods are described which direct a molten polymeric material into cavities corresponding to the mold sections.
