Haptic And Optic Junction Patents (Class 623/6.46)
  • Patent number: 6306167
    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”).

  • Patent number: 6251312
    Abstract: New methods for producing intraocular lenses (IOLs) include a combination of steps which provide outstanding pull strength between the fixation member of the IOL and the optic of the IOL without requiring the lens body region of the fixation member to have enlarged anchor structures. In one embodiment, the present methods include providing an optic member having a recess; providing a fixation member having a lens bonding region free of enlarged anchor structures; placing the lens bonding region into the recess; and thereafter doing at least one of reducing the size of the recess and increasing the cross-sectional area of the lens bonding region. The lens bonding region of the fixation member is thereby secured to the optic member.

  • Patent number: 6200343
    Abstract: An intra-ocular lens having an optical lens part can be implanted in the anterior chamber of an eye in front of the iris. The lens has haptic loops which, in the implanted condition, are guided through incisions in the iris and are supported in the posterior chamber of the eye, particularly in the area of the sulcus ciliaris.
