20120075579 | TRANSLATING PRESBYOPIC CONTACT LENS - Lenses for correcting presbyopia are translating, multifocal contact lenses with pseudotruncations which are asymmetric about the vertical meridian. | 03-29-2012 |
20120075580 | TRANSLATING PRESBYOPIC CONTACT LENS - Lenses for correcting presbyopia are translating, multifocal contact lenses with pseudotruncations which are asymmetric about the vertical meridian. | 03-29-2012 |

20130077045 | METHOD FOR DESIGNING NON-ROUND SOFT CONTACT LENSES - A method for optimizing the performance in centration, rotation and stability of contact lenses makes use of the upper and lower eyelid geometries to maximize the lens-lid interaction for two different contact lens positions on the eye. The contact lenses are non-round lenses for maximum interaction with the eyelids. | 03-28-2013 |
20130182214 | FRACTAL FEATURES FOR ENHANCED TEAR EXCHANGE - Feature patterns may be incorporated into the peripheral region of the back curve surface of contact lenses in order to increase tear exchange between the contact lens and the cornea. The feature patterns may be based upon fractal geometry and be incorporated anywhere in the periphery of the lens. The placement feature patterns are preferably determined utilizing a combination of simulations and experimentation. | 07-18-2013 |
20130313404 | REDUCED-TILT BACK PLASTIC FEATURE FOR A CONTACT LENS MOLD - A mold assembly for manufacturing ophthalmic lenses which comprises an anti-tilt feature that prevent relative movement of one half of the mold assembly relative to the other half of the mold assembly. The anti-tilt feature ensures that the edges of the ophthalmic lenses are symmetric around their periphery. | 11-28-2013 |
20140118683 | CONTACT LENS WITH IMPROVED FITTING CHARACTERISTICS - A contact lens or pair of contact lenses may be designed such that the contact lens is circular or non-circular, planar or non planar, continuous or discontinuous, or any combination thereof to improve the fit of the contact lens on eye. This improved fit contact lens provides improved centration, improved rotation and/or translation and improved tear exchange on eye. | 05-01-2014 |
20150146160 | CONTACT LENSES WITH IMPROVED OXYGEN TRANSMISSION - Contact lenses may be designed with locally thinned regions to increase oxygen transmissibility to the eye. The locally thinned regions are preferably positioned outside of the optic zone and in the thicker peripheral zone. For a contact lens formed from a specific material, creating local thinner regions, for example, dimples in the back curve surface of the lens, provides an effective and efficient means for increasing oxygen diffusion. | 05-28-2015 |
