| Number | Title | Issue Date |
| 7159979 | Rotationally stabilized contact lenses The invention provides a lens in which the lens periphery is controlled as to each of thickness differential and both the rate of change from thinner to thicker regions and the shape of the transition from thinner to thicker regions within each of the dual thin zone... | 01/09/2007 |
| 6939005 | Rotationally stabilized contact lenses The invention provides a lens in which the lens periphery is controlled as to each of thickness differential and both the rate of change from thinner to thicker regions and the shape of the transition from thinner to thicker regions within each of the dual thin zone... | 09/06/2005 |
| 6454409 | Contact lenses Contact lenses that have a back edge designed so that the flat portion of the edge does not rest on the wearer's conjunctiva are provided. The lenses of the invention exhibit good lens handling as well as excellent on-eye comfort and movement.... | 09/24/2002 |
| 6444145 | Molds for use in contact lens production The invention provides molds useful for the production of lenses with contoured edges. In particular, the molds permit production of a lens with an edge shaped to avoid its impingement on the lens wearer's conjuntival membrane.... | 09/03/2002 |
| 6270218 | Contact lenses with off-axis bevel The invention provides contact lenses with off-axis bevels. The bevels aid in increasing stability of the lens on the eye and form a smooth junction with the lenticular zone of the lens.... | 08/07/2001 |
| 6183082 | Contact lenses with constant peripheral geometry The invention provides contact lenses. In particular, the invention relates to contact lenses in which the geometry of the lens periphery remains constant with changes in the optic zone curvature.... | 02/06/2001 |
| 6179420 | Multifocal ophthalmic lenses The invention provides a pair of multifocal lenses for the correction of presbyopia. The dominant eye lens has an optic zone with the distance optical power required and additional zones of either or both distance and near optical power. The non-dominant ... | 01/30/2001 |
| 6176580 | Method of designing and fitting contact lenses taking into account material properties of the lenses A method for fitting and designing ophthalmic lenses that yields improved visual acuity and takes into account individual lens fitting characteristics is provided. More specifically, the method of the invention takes into account the materials properties ... | 01/23/2001 |
| 6176578 | Toric contact lenses The invention provides toric contact lenses that exhibit good fit and good on-eye orientation regardless of whether the lens has a plus or a minus spherical power.... | 01/23/2001 |
| 5861114 | Method of manufacturing complex optical designs in soft contact lenses A method of manufacturing complex optical surfaces in soft contact lenses includes a first step of defining the complex optical surfaces with a computer assisted drafting program using a mix of patient determined parameters and selected manufacturing proc... | 01/19/1999 |
| 5805260 | Combined multifocal toric lens designs Combined multifocal toric lens designs are disclosed which combine a correction for astigmatism, either corneal or lenticular, with a correction for presbyopia. One of the front and back surfaces of the lens defines a toric surface for an astigmatic optic... | 09/08/1998 |
| 5650838 | Programmable smooth junctions on lenses Programmable smooth junctions are provided for lenses and molds therefor, particularly for toric lens designs, which enable a numerically controlled (NC) machine to be programmed to machine smooth junctions or transitions between adjacent regions of a len... | 07/22/1997 |
| 5650837 | Rotationally stable contact lens designs Non-ballasted, eyelid rotationally stabilized designs are disclosed for use in toric or multifocal toric contact lenses. The back surface of the lens includes a toric or multifocal toric surface and also thin top and bottom zones (slab offs) to achieve ey... | 07/22/1997 |
