Publication number: 20170038604Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include a deformable inner portion and a deformable peripheral portion. When disposed over the optical region of an eye, the inner portion is configured so that engagement of the posterior surface against the eye deforms the posterior surface so that the posterior surface has a shape diverging form the refractive shape of the epithelium when viewing with the eye through the ophthalmic lens. The rigidity of the inner portion is greater than the rigidity of the peripheral portion and the ophthalmic lenses are configured to allow movement relative to the eye upon blinking of the eye and to be substantially centered on the optical region of the cornea following the blinking of the eye. Methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses are also disclosed.Type: ApplicationFiled: July 13, 2016Publication date: February 9, 2017Inventors: Eugene de Juan, JR., Cary J. Reich, Yair Alster, Matt Clarke, Kuangmon Ashley Tuan, Brian Levy, Raymond Lum, Jose D. Alejandro

Publication number: 20170023800Abstract: A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10?4 Pa*m3 to about 5×10?4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.Type: ApplicationFiled: October 10, 2016Publication date: January 26, 2017Inventors: Eugene de Juan, JR., Cary J. Reich, Yair Alster, K. Angela Macfarlane, Doug Rimer, Douglas Sutton, Dean Carson, Enrique Barragan, Matt Clarke, Ashley Tuan, Brian Levy

Patent number: 9395558Abstract: Methods and apparatus can fit coverings to treat eyes. The covering can be identified so as to provide improved flow of tear liquid under the covering. The covering can be identified based on an inner corneal curvature and an outer corneal curvature and one or more of a limbus sag height or a conjunctival sag height.

Publication number: 20140362338Abstract: An eye covering such as a contact lens may comprise one or more structures to pump tear liquid under the covering such that the covering can remain in the eye and correct vision for an extended amount of time. In many embodiments, the covering comprises a material having fenestrations to draw tear liquid under the covering and an outer portion shaped to contact the conjunctiva over the sclera, such that when the eye closes pressure of one or more eyelids urges tear liquid through one or more fenestrations and under the outer portion shaped to contact the conjunctiva. When the eye blinks, the pressure of the one or more eyelids can urge the covering toward the cornea such that tear liquid can pass through the fenestrations.Type: ApplicationFiled: August 25, 2014Publication date: December 11, 2014Inventors: Eugene de Juan, JR., Cary J.

Patent number: 8894202Abstract: Multifocal contact lenses and methods and uses are described. The multifocal contact lenses include an optic zone. The optic zone has an aspheric power profile that provides a near vision refractive power and a distance vision refractive power, and provides an Add power that corresponds to the difference between the near vision refractive power and the distance vision refractive power. The multifocal contact lenses can improve binocular vision of presbyopic subjects by being prescribed such that the non-dominant eye contact lens is over-corrected for distance vision, and both multifocal contact lenses are under-corrected for the Add power requirement of the subject. Batches and sets of multifocal contact lenses are also described.Type: GrantFiled: January 22, 2013Date of Patent: November 25, 2014Assignee: CooperVision International Holding Company, LPInventors: Arthur Back, Kuang-mon Ashley Tuan
