Abstract
Disclosed is a method for producing an intraocular lens including an optic and at least one haptic. In one embodiment, the method comprises: exposing the lens bonding region of the haptic to a plasma at conditions effective to enhance the bondability of the lens bonding region to the optic; and bonding the exposed lens bonding region to an optic. The plasma exposed haptic may be coated with a material, e.g., to preserve the enhanced bondability property, prior to bonding the coated lens bonding portion to the optic. Intraocular lenses having enhanced haptic-optic bonding are also disclosed.
Claims17
An intraocular lens comprising:
- an optic;
- and
- at least one haptic including a lens bonding region bonded to said optic, wherein said lens bonding region is exposed to plasma prior to being bonded to said optic, and the bond strength between said haptic and said optic is increased as a result of said exposure relative to a substantially identical intraocular lens including a haptic the lens bonding region of which is not subjected to said exposure.
An intraocular lens comprising:
- an optic;
- and
- at least one haptic including a lens bonding region bonded to said optic, wherein said lens bonding region is exposed, prior to being bonded to said optic, to an activated gas plasma formed from a gas selected from the group consisting of oxygen, nitrogen, argon, and mixtures thereof, the bond strength between said haptic and said optic is increased as a result of said exposure relative to a substantially identical intraocular lens including a haptic the lens bonding region of which is not subjected to said exposure.
An intraocular lens comprising:
- an optic;
- and
- at least one haptic including a lens bonding region the surface of which has been treated by being exposed to a plasma at conditions effective to increase the bond strength between said optic and said haptic relative to a substantially identical intraocular lens including a haptic the lens bonding region of which is not subjected to said exposure.
