Abstract
A deformable intraocular lens having a resilient haptic portion anchored into a deformable lens portion. Preferably, the haptic portion is anchored in a manner to the lens portion to provide a compressive type of connection therebetween. This anchoring configuration is particularly suitable for use with deformable intraocular lenses made of a collagen-based lens material (e.g. “Collamer”).
Claims19
A deformable intraocular lens, comprising:
- a deformable lens portion including at least one connecting portion, said connecting portion provided with an anchoring hole extending through said connecting portion;
- and
- at least one resilient haptic portion, said resilient haptic portion connected to said deformable lens portion, said resilient haptic portion being provided with a connecting end portion including a barb portion and a stop portion, said stop portion located adjacent to an outer opening into said anchoring hole and configured for cooperating and stopping with an outer edge located adjacent to said opening into said anchoring hole and said barb portion configured for cooperating and anchoring with an indentation located within said anchoring hole, said connecting end portion being configured to allow said haptic portion to be assembled into said anchoring hole by threading said haptic portion in at least one direction through said anchoring hole.
