An implanting device is used for implanting a membrane in a biological tissue. The implanting device includes a sleeve, a membrane storage element, an injection element and a bubble generating element. The membrane storage element is fixed at the sleeve. The injection element is inserted in the sleeve and the membrane storage element, and includes a capturing end and connecting end. The capturing end is for capturing the membrane and has a hole. The bubble generating element is connected to the connecting end, and is for providing a gas that is then outputted via the hole. By the rotation of the injection element, the capturing end extends straight out of the membrane storage element or retracts straight into the membrane storage element.

A tear shaping structure or structures that shape a tear film of an eye thereby enabling a desired refractive effect. The tear shaping structure includes a supporting structure supporting a plurality of capillary action members, the capillary action members being spaced apart and arranged in such a way as to create a desired refractive lens effect by shaping the tear film of an eye.

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.

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 +5.00D.

The present disclosure provides intra ocular implants and methods of using same to treat various refraction errors in a patient's eye.

A method of corneal implantation with cross-linking is disclosed herein. In one or more embodiments, the method includes the steps of: (i) forming a flap in a cornea of an eye so as to expose a stromal tissue of the cornea underlying the flap; (ii) pivoting the flap so as to expose the stromal tissue of the cornea underlying the flap; (iii) inserting an implant under the flap so as to overlie the stromal tissue of the cornea; (iv) applying laser energy and/or microwaves to the implant in the eye so as to modify the refractive power of the implant; (v) applying a cross-linking solution that includes a photosensitizer to the implant; (vi) covering the implant with the flap; and (vii) irradiating the implant so as to activate cross-linkers in the implant, and thereby cross-link the implant and the stromal tissue of the cornea surrounding the implant.

A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient includes an anterior surface, a posterior surface, and a plurality of holes. The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is configured to reside adjacent a second corneal layer. The plurality of holes extends at least partially between the anterior surface and the posterior surface. The holes of the plurality of holes are configured to substantially eliminate visible diffraction patterns.

An artificial cornea and an associated manufacturing method are disclosed. The artificial cornea has two sides, each of which has an associated microstructure. In an embodiment, microlines can be provided on an anterior side, and a posterior side can have micropores. Both the geometry of the microstructures and their dimensions can be customized for an individual patient. The geometry of the artificial cornea itself and its dimensions can also be customized as such. In addition, the lifetime of the artificial cornea can be significantly enhanced by adding co-polymer(s) into the hydrogel to strengthen its mechanical properties. Patient recovery can be aided by adding peptides into the artificial cornea surfaces to improve cell growth post-operation.

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 lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component and a secondary spherical aberration component. The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 0.35, the second RIQ is at least 0.1 and the through focus range is at least 1.8 Diopters.
