  • Method of forming a biomedical device including an ophthalmic device
    Patent number: 7850878
    Abstract: A method is provided of forming a biomedical device in a casting mold which has an anterior mold section and a posterior mold section, wherein one of the mold sections includes a plurality of radially extending ribs and the remaining mold section includes an annular shoulder for engaging an outer end of the ribs to define a mold cavity. The method includes engaging the mold sections along a peripheral seal of the mold cavity and a plurality of circumferentially spaced contact points on a shoulder of one of the mold sections. Cured excess material bonds to the ribs of the one mold section and provides repeatable retention and location of the excess material after formation of the biomedical device.
