The present invention uses 3 dimensional printer technologies to create specialized contact lenses by building up optical features onto a shell of a contact lens. In this context, a shell is a curved disk with the same radius of curvature on the front and back surface providing a spherical base curve to fit the cornea and no optical power on the front curve. Starting with such a shell, the present invention provides that the 3-dimensional printer is utilized to build optical features on to the front surface.

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.

Embodiments of this invention generally relate to systems and methods for optical treatment and more particularly to non-invasive refractive treatment method based on sub wavelength particle implantation. In an embodiment, a method for optical treatment identifies an optical aberration of an eye, determines a dopant delivery device configuration in response to the optical aberration of the eye, wherein the determined dopant delivery device is configured to impose a desired correction to the eye to mitigate the identified optical aberration of the eye by applying a doping pattern to the eye so as to locally change a refractive index of the eye.

The present invention relates to an intracorneal lens (1), comprising a circular main body having a convex front surface and a convex rear surface, characterized in that the convex front surface has a single uniform radius of curvature (Rcv) and the concave rear surface has a radius of curvature (Rcci). The radius of curvature of the concave rear surface is greater than the average radius of the cornea by 0.1 mm to 2 mm, preferably 0.2 to 1.5 mm, in particular preferably 0.5 to 1 mm. The present invention further relates to a kit, comprising a storage unit (15) and a pre-load unit (P) inside the storage unit (15). The storage unit (15) is made of a watertight material and can be closed watertight by means of a plug (16). The pre-load unit (P) is fitted with the intracorneal lens according to the invention.

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).

Corneal implants that have an implant body comprising manufactured corneal tissue. Methods of manufacturing corneal implant that include manufacturing a volume of corneal tissue. Corneal implants that have an implant body made from cornea tissue removed from a living subject.

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 method of preventing rejection of an implant in the eye, includes forming a flap in the cornea of the eye, inserting an implant under the flap, cross linking corneal tissue surrounding an implant to make the corneal tissue surrounding an implant less vulnerable to enzymatic degradation, inserting polymeric material under the corneal flap so as to overlie corneal tissue, compressing a layer of the cornea from outside using a lens having a predetermined curvature to correct refractive error of the cornea, and cross linking corneal tissue that the polymeric material overlies.

A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.

Contact lenses incorporate mask lens designs that at least one of slow, retard or preventing myopia progression. The lens includes a first zone at a center of the lens; at least one peripheral zone surrounding the center and having a dioptric power that is different than that at the center; and an opaque mask beginning at a radial distance from the center, thereby providing a lens power profile having substantially equivalent foveal vision correction to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.
