A corneal inlay and pinhole lens structure for implantation into a cornea of an eye is disclosed herein. In one embodiment, a corneal inlay for implantation into a cornea of an eye includes an inlay body formed from natural tissue of a donor cornea; and a central pinhole disposed in the inlay body, the central pinhole being surrounded by a darkened bounding wall. In another embodiment, a pinhole lens structure includes an insertable pinhole body defining a through pinhole of approximately 0.9-2.0 mm in diameter with a surrounding darkened wall having an approximately 0.1-1 mm wall thickness, the insertable pinhole body configured to be inserted into a corneal pocket in a cornea of an eye.

Devices and methods for the amelioration of ectatic corneal disorders using corneal augmentations derived from corneal tissue are disclosed. The shape of the augmentation is determined using data obtained from mapping of a patient's cornea based on computerized corneal topography and tomography. Factors considered include the maximum keratometry and specific iso-deviation contours. In one embodiment, an augmentation is a corneal inlay, intended for insertion into an intrastromal pocket. In a further embodiment, the augmentation is a corneal onlay, intended to be positioned over a region of the cornea from which the epithelial layer has been removed. The corneal onlay is held in place until the epithelial layer regrows over the augmentation. In a further embodiment, the inlay or onlay augmentation is followed by a post-augmentation, further reshaping of the corneal augmentation. In one embodiment, this further reshaping is photorefractive keratectomy (PRK) surgery.

The present disclosure is directed to lenses, devices, methods and / or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and / or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and / or methods include embodiments that address foveal and / or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and / or refractive surgery.

The invention provides a non-diffractive trifocal lens for human eyes. The method is realized by introducing wavefront aberration into a central pupil of a human eye on the basis of the focal power phi 0 of a reference single-focus lens. The wavefront aberration introduced into the central pupil of the human eye involves: 1) introducing a positive spherical aberration into a first region and a negative spherical aberration into a second region, the first region and the second region being concentric and forming a central optical sub-region having a diameter D1 between 2.5 mm and 4.5 mm, the central optical sub-region of the lens covering the central pupil of the human eye; (2) a positive focusing focal power offset delta phi 0 is further introduced into a central area with the diameter smaller than 2.5 mm in the central optical sub-area of the lens, the non-diffractive trifocal lens is suitable for invisible contact lenses, implantable contact lenses, intraocular lenses, lens eye artificial crystal shapes, adjustable artificial crystal shapes, corneal mosaic lenses, and eyepieces for virtual reality displays, game goggles, microscopes, telescopes and the like.

This invention is directed to compounds and compositions which are designed for use in light adjustable ophthalmic devices, such as intraocular implants, intraocular lenses, phakic intraocular lenses, contact lenses, orthokeratology lenses, rigid gas permeable lenses, corneal inlays, corneal outlays, or corneal inserts. The inventive compositions are produced from reactive monomer mixtures which when polymerized form polymers or polymeric networks having editable refractive indices. Such inventive compositions when exposed to light of certain wavelengths undergo intramolecular cycloaddition reactions thereby changing the refractive index in the irradiated regions. When used in ophthalmic devices, the inventive compositions enable post-manufacturing and / or post-operative adjustments to the optics of the devices by spatially modifying the refractive index. For example, the vision of a patient with an intraocular lens made of the inventive compositions can be fine-tuned after implantation and healing by a light treatment of the intraocular lens.
