  • Publication number: 20150209274
    Abstract: A drug eluting member is adapted to be attachable onto a perimeter edge of a lens portion of an intraocular lens, the drug eluting member including an interfacing portion adapted to receive a portion of the perimeter edge. A drug eluting device includes a first and second drug eluting members adapted to be attached to first and second portions, respectively of the perimeter edge. A method attaches the drug eluting member to the perimeter edge by positioning a holding device with the drug eluting member held therein against a portion of the perimeter edge; and releasing the drug eluting member from the holding device portion. A method of fabricating the drug eluting member includes providing a mold for molding the drug eluting member; discharging a forming solution from a nozzle onto the mold; and forming the drug eluting member.
