Methods of manufacturing and implanting corneal inlays, such as small diameter corneal inlays, are provided. The methods include manufacturing an implant body to have a meniscus shape with a small diameter and an index of refraction, and implanting the implant body in a corneal bed of a cornea. The inlays cause a change in an anterior surface of the cornea after implantation due to the implant body.

Methods and systems for manufacturing a wavefront-guided scleral lens prosthetic device customized for an eye of a patient include obtaining a first scleral lens prosthetic device with a central optic zone configured to vault over the eye's cornea and a peripheral haptic zone configured to align with the eye's sclera, collecting measurements of any offset and/or rotation of the first scleral lens prosthetic device relative to the eye's pupil and of any aberrations, particularly higher-order aberrations, generating a wavefront-guided profile from the measurements, and fabricating a second scleral lens prosthetic device with the profile on a surface of a central optic zone configured to vault over the eye's cornea and a peripheral haptic zone customized to align with the eye's sclera.

The present disclosure relates to an orthokeratology lens which may comprise an inner surface facing a cornea of a human eye when the orthokeratology lens is worn and an outer surface opposite the inner surface, the inner surface comprising a centrally located base are zone, wherein the base arc zone is configured for pressing and shaping an anterior surface of the cornea to have a shape that conforms to the base are zone, wherein the base arc zone comprises two or more regions, at least two of the two or more regions having different radii of curvature. The present disclosure also relates to a method for making orthokeratology lenses.

Additive manufacturing techniques are used to form an artificial intra-ocular lens (IOL) directly inside the human eye. Small openings are formed in the cornea and lens capsule of the eye, and the crystalline lens is broken up and removed through the openings; then, a material is injected into the lens capsule through the openings, and the focal spot of a pulse laser beam is scanned in a defined pattern in the lens capsule, to transform the material in the vicinity of the lase focal spot to form the IOL in a layer-by-layer manner. In one embodiment, stereolithography techniques are used where a pulse UV laser source is used to photosolidify a photopolymer resin. The liquefied resin is injected into the eye through the openings, after which only part of the resin, having the shape of the desired IOL, is selectively cured with the UV laser beam, via progressive layer formation.

A contact lens has a core that is thick enough to accommodate a payload. The core has a base surface for mounting the contact lens to the sclera of the user's eye. It also provides mechanical integrity to carry the payload. The contact lens also includes an outer covering and an inner covering. Each covering is a thin layer of gas-permeable material shaped to form an air gap between the covering and the core. The two air gaps are connected by an air path that traverses the core. Oxygen from an outside environment passes through the gas-permeable outer covering to reach the outer air gap, through the air path to the inner air gap, and through the gas-permeable inner covering to reach the cornea of the wearer's eye.

The present disclosure relates to an orthokeratology lens which may comprise an inner surface facing a cornea of a human eye when the orthokeratology lens is worn and an outer surface opposite the inner surface the inner surface comprising a centrally located base are zone, wherein the base arc zone is configure for pressing and shaping an anterior surface of the cornea to have a shape that conforms to the base are zone, wherein the base arc zone comprises two or more regions at least two of the two or more regions having different radii of curvature. The present disclosure also relates to a method for making orthokeratology he lenses.

Methods of implanting corneal inlays, such as small diameter corneal inlays. The inlays may be adapted to change the corneal surface curvature to provide central near vision and peripheral distance vision.

One embodiment of a rigid gas permeable ocular lens may be formed by a process including forming a portion of a mold including a first side having a profile shaped to form an anterior surface of the rigid gas permeable ocular lens, applying a liquid lens material to the first side of the portion of the mold, and at least partially curing the liquid lens material to form the rigid gas permeable ocular lens. Methods of forming molds for rigid gas permeable ocular lenses, including molds for casting rigid gas permeable ocular lenses having a desired surface smoothness and desired dimensional tolerances are also provided.

Ophthalmic lenses and methods of manufacture thereof are disclosed. The ophthalmic lenses include metasurface features that define a metasurface array on a lens body. The metasurface array can be tuned to modify an optical property, such as glare reduction, of the ophthalmic lens using an arrangement of metasurface building elements dimensioned from an optical wavelength, including being dimensioned smaller than an optical wavelength. The ophthalmic lenses can be subject to physical manipulation, including rolling or other folding during an installation procedure, and as such, the modified optical property induced by the metasurface array can be maintained after such manipulation. The ophthalmic lenses can be formed using a molding process, in which the metasurface array is associated with a non-solid material and formed into a lens shape with the material.

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.
