A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10-4 Pa*m3 to about 5×10-4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

In certain embodiments, a system for performing refractive treatment of an eye comprises a laser, a printer, and a computer. The laser emits a laser beam to prepare the eye for the refractive treatment. The printer prints material onto a print area of a target. The printer comprises a printer head and a printer controller. The printer head directs the material onto the print area, and the printer controller moves the printer head to direct the material onto a specific location of the print area. The computer comprises a memory and processors. The memory stores instructions for a pattern for the target. The pattern is designed to provide the refractive treatment for the eye. The processors instruct the printer controller to move the printer head to print the material onto the print area according to the pattern.

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.

A flexible integral intracorneal ring for the treatment and correction of vision disorders and corneal malformations, which is annular, continuous or integral and flexible, all of which allows to inject the ring into the stroma thanks to its outstanding flexibility due to its structural design and also allows to increase your rigidity when inserted.

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

An optical device comprising an optical hydrogel with select regions that have been irradiated with laser light having a pulse energy from 0.01 nJ to 50 nJ and a wavelength from 600 nm to 900 nm. The irradiated regions are characterized by a positive change in refractive index of from 0.01 to 0.06, and exhibit little or no scattering loss. The optical hydrogel is prepared with a hydrophilic monomer.

A system includes a scleral prosthesis and an insert. The scleral prosthesis includes a first end configured to be pulled through a scleral tunnel in an eye and a second end. Each end is wider than a middle portion of the scleral prosthesis. Two portions form the first end of the scleral prosthesis, and the portions are separated along at least half of a length of the scleral prosthesis. The scleral prosthesis is formed from a single integrated piece of material. The second end is undivided. The insert is configured to be placeable between the two portions. The two portions may be separated from one another without external interference, and the two portions may be configured to be pushed towards each other in order to reduce a width of the first end and then separate after release.

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 device for the transplantation of a Descemet's membrane includes a longitudinal tube having an inner cavity, an inlet opening through which it is possible to introduce the Descemet's membrane into the device, and an outlet opening through which it is possible to eject the Descemet's membrane from the device, especially into the anterior eye chamber of a patient, wherein the device also includes, at least in the region of the outlet opening, a separation element which protrudes from the inner wall region of the tube into the cavity, especially a first separation element, the separation element dividing the cavity at least regionally, in particular dividing it in a region close to the separation element.

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.
