Haptic Has Different Color From Optic Patents (Class 623/6.48)
  • Patent number: 9439754
    Abstract: The present invention relates to a prosthetic capsular bag and method for inserting the same. The prosthetic capsular bag helps to maintain the volume of the natural capsular bag, thereby stabilizing the effective lens position of an IOL so that refractive outcomes may be improved with cataract surgery. The prosthetic capsular bag further provides an integrated refractive surface, providing a means for experimentally determining an effective lens position prior to inserting an IOL.

  • Patent number: 8308800
    Abstract: Intraocular lenses with high contrast haptics, materials and methods for making optical blanks and lenses, and methods of use are disclosed and claimed. Such lenses may provide easily recognizable visual cues that may be used to detect and correct misorientation of lenses prior to and during use.

  • Publication number: 20040068317
    Abstract: The fixation members of an anterior chamber intraocular lens (IOL) are provided with indicators for aiding the sizing and placement of the IOL. In one embodiment, the indicators are lines, dots or other contrast based indicia formed at a predetermined distance away from the distal tips of the fixation members. In another embodiment, the indicators are colored zones extending a predetermined distance radially inwardly from the distal tips. The predetermined distance is selected such that the indicators are visible at the edge of a patient's cornea, even though the distal tips of the haptic members are hidden behind the scleral rim. The surgeon can evaluate whether the IOL is centered by checking that the indicators are symmetrical relative one another. Similarly, the surgeon can tell whether the IOL is properly sized by determining the distance between each line, or the edge of each colored zone, and the edge of the scleral rim, and comparing this distance to a desired value.

  • Publication number: 20020120329
    Abstract: Intraocular lenses include a reduced size optic adapted to focus light toward a retina of an eye and an at least partially opaque movement assembly coupled to the optic. In one embodiment, the optic has a far vision correction power and the movement assembly is at least partially black and adapted to cooperate with the eye to effect accommodating movement of the optic, preferably upon radial compression by a capsular bag of the eye. The optic preferably vaults anteriorly relative to the movement assembly. Enhanced amounts of accommodation preferably are achieved. Combinations of first and second optics and at least partially opaque movement assembly are also provided.

  • Patent number: 6235055
    Abstract: An intraocular lens incorporating a central lens optic and a plurality of haptics, e.g., flexible haptic arms or haptic plates, having anterior and posterior sides that are visually distinguishable from each other. For example, the anterior and posterior sides of the haptics can have contrasting colors or textures. This reduces the possibility that the intraocular lens might mistakenly be implanted in a reversed orientation, with its anterior side facing rearwardly and its posterior side facing forwardly.
