Methods of manufacturing a corneal implant that include creating an implant body that has a meniscus shape, a diameter of approximately 2.5 mm or less, and an index of refraction of 1.376. The implant body can further have a central thickness and an outer edge thickness.

Systems and methods employ bioresorbable corneal implants to treat corneal ectatic disorders and/or refractive errors. The corneal implants may be formed from a porous microstructure that can encourage the proliferation of endogenous keratocytes. As such, the corneal implants act as tissue scaffolds that promote tissue growth to increase the biomechanical stability and/or change the shape of the cornea. Over time, the corneal implants may resorb via hydrolysis or enzymatic breakdown, negating the risks of inflammation, scarring, or foreign body response. The corneal implants may also employ drug coating(s) to promote tissue growth.

Contact lenses incorporate high plus or add power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.00 D.

A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

Methods for treating presbyopia in a patient's eye involve inducing spherical aberration in a central area of the pupil. In embodiments, refractive properties of an eye are measured to obtain a baseline refractive correction. A lens for wearing on the eye is provided, or an optical device is implanted in the eye, or corneal tissue is removed to create spherical aberration or a distribution of spherical aberrations beyond the baseline refractive correction in the central area of the pupil. The central area of the pupil has a diameter of between 1.5 mm and 4.0 mm and has negligible spherical aberration without the treatment.

A method for treating hyperopia or presbyopia in a patient, the method comprising making a cut deep in the patient's cornea to create a two-dimensional slit adjacent to and generally parallel to an anterior surface of the cornea and injecting a liquid or semi-solid transparent filler material into the deep cut in an amount sufficient to flatten the posterior surface of the cornea to increase the refractive power of the cornea by a predetermined correction of up to about 5 diopters due to the physical flattening of the posterior surface of the cornea, wherein the transparent filler material comprises a refractive index of about 1.3 to about 1.6, and forms a corneal implant with a lenticular shape within the cornea.

A method of intracorneal lens implantation with a cross-linked cornea is disclosed herein. The method includes forming a pocket in a cornea of an eye, applying a photosensitizer inside the pocket so that the photosensitizer permeates at least a portion of the tissue bounding the pocket, the photosensitizer facilitating cross-linking of the tissue bounding the pocket; irradiating the cornea so as to activate cross-linkers in the portion of the tissue bounding the pocket, and thereby kill cells therein; inserting a lens implant into the pocket; and applying laser energy to the lens implant in the pocket using a laser so as to correct refractive errors of the lens implant and/or the eye in a non-invasive manner. In other embodiments, a lens implant is soaked in a cross-linking solution that includes a photosensitizer prior to being inserted into the pocket in the cornea of an eye.

A pair of ophthalmic lens having an electronic system is described herein for communicating between them using ultrasound transducers for creating a sound pressure wave(s) propagated through the eyes and the optic nerve of the wearer of the contact lenses. The ophthalmic lenses include at least one ultrasound module having at least one transducer such as a pair of transmit and receive transducers and a transceiver transducer that are optic nerve facing. The ultrasound module includes additional components for the transmission and receipt of the sound pressure wave(s). In an alternative embodiment, there is one ultrasound module with a multiplexer connected to a plurality of transducers. In at least one embodiment, the sound pressure wave(s) encodes a message between the ophthalmic lenses.

An ophthalmic lens system for reducing the risk of progression of a myopic eye by selectively maintaining, inducing or creating asymmetry of the peripheral retinal profile for the eye. A method for reducing the risk of progression of myopia comprising determining the magnitude of asymmetry of the on-axis/off-axis refractive error profile or eye length profile of the eye and providing an ophthalmic lens system that corrects for and provides acceptable on-axis vision and simultaneously controls the position of the off-axis refractive error profile or eye length profile such that resultant profile of the eye is asymmetric.
