Treatment to improve adhesive properties of corneal implant
A method is described of improving adhesion of an ocular implant to corneal tissue by forming an implant adhesive layer on the ocular implant, the implant adhesive layer having greater adhesive strength than a rest of the implant or by forming a corneal adhesive layer on a posterior surface of a posterior portion of the corneal tissue, the corneal adhesive layer having greater adhesive strength than a rest of the corneal tissue.
TREATMENT TO IMPROVE ADHESIVE PROPERTIES OF CORNEAL IMPLANT
A method is described of improving adhesion of an ocular implant to corneal tissue by forming an implant adhesive layer on the ocular implant, the implant adhesive layer having greater adhesive strength than a rest of the implant or by forming a corneal adhesive layer on a posterior surface of a posterior portion of the corneal tissue, the corneal adhesive layer having greater adhesive strength than a rest of the corneal tissue.
Tissue-Augmented Corneal Inlay Surgery Technique
A tissue-augmented corneal inlay surgery technique is disclosed herein. In one embodiment, the surgery method includes the steps of: (i) implanting a corneal inlay into a recipient cornea of an eye of a patient; (ii) applying laser energy to a central portion of the corneal inlay and a portion of stromal tissue of the recipient cornea underneath the corneal inlay so as to modify the refractive power of the eye; (iii) applying a cross-linking solution that includes a photosensitizer to the recipient cornea of the eye of the patient; and (iv) irradiating the corneal inlay and surrounding corneal tissue so as to activate cross-linkers in the corneal inlay and the surrounding corneal tissue. In this embodiment, the central portion of the corneal inlay remains clear for the patient without being obstructed by swollen tissue so that the patient is able to see immediately after the corneal inlay surgery.
Lenses, devices, methods and systems for refractive error
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.
Ophthalmic optical lens for vision correction having one or more areas of more positive power
The present disclosure is directed to lens, methods of making, designing lens and/or methods using lens in which performance may be improved by providing one or more steps in the central portion of the optical zone and one or more steps in the peripheral portion of the optic zone. In some embodiments, such lens may be useful for correcting refractive error of an eye and/or for controlling eye growth.
Keratoprosthesis apparatuses, systems, and methods
The present disclosure relates to keratoprosthesis apparatuses and methods of manufacturing keratoprosthesis apparatuses. The keratoprosthesis apparatus includes a circular backplate including a central aperture extending through the backplate from a face of the backplate to a posterior surface of the backplate. The circular backplate has a dome shape and comprises a plurality of spaced apart elongated slits extending radially outwardly from a central portion of the backplate. The plurality of spaced apart elongated slits surround the central aperture and extending through the backplate from the face of the backplate to the posterior of the backplate.
Vision correction with laser refractive index changes
Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or optical tissues is performed to address various types of vision correction.
Refractive treatment of an eye by printing material onto a target
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.
LIGHT CONTROL DEVICES AND METHODS FOR REGIONAL VARIATION OF VISUAL INFORMATION AND SAMPLING
Exemplary light control devices and methods provide a regional variation of visual information and sampling (V-VIS) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.
Structures and methods for tear shaping for refractive correction
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.
