  • Patent number: 10195018
    Abstract: An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.

  • Publication number: 20130335697
    Abstract: Described herein is a contact lens with high lubricity to eye tissue/fluid and inhibited nucleation on its surface. The contact lens has a surface textured to form a matrix of micro-scale and/or nano-scale solid (e.g., gel) features spaced sufficiently close to stably contain an impregnating liquid therebetween. The impregnating liquid fills spaces between the solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface and despite contact with the eye tissue during normal wear, insertion, and removal of the contact lens.

  • Publication number: 20130308092
    Abstract: A contact lens assembly includes a proximal layer formed from a gas-permeable material, a distal layer with an optical element, an air cavity disposed between the proximal layer and the distal layer, wherein oxygen concentration across the air cavity is substantially uniform, and an gas transport region surrounding the air cavity for communicating gas between the air cavity and atmosphere. The contact lens assembly may further include a plurality of fins disposed within the air cavity where the plurality of fins has openings therethrough. One or both of the upper and lower surfaces of the air cavity may have an anti-reflection coating formed thereon.

  • Publication number: 20130278890
    Abstract: 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.

  • Publication number: 20130182214
    Abstract: 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.

  • Publication number: 20130077044
    Abstract: 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.

  • Patent number: 8393733
    Abstract: The invention provides methods for designing contact lenses and contact lenses designed according to the method, which lenses provide an improved method for presbyopia correction compared to conventional lenses and methods. It is a discovery of the invention that improved performance and reduced design time can be obtained by using lens pairs that act synergistically to provide the lens wearer with good binocularity and consistent performance in near, intermediate and distance vision.
