An ocular protection device and treatment methods are disclosed. The device has a corneal shield with an attached handle. The handle may be used to move the corneal shield to better protect the eye from various treatment modalities. The handle may also be used to place tension on the eyelid to counteract the forces imposed by a treatment handpiece. A procedure for treating the eye is disclosed where multiple passes with a treatment handpiece cause a gradual increase in the temperature of an eyelid up to a treatment temperature. Once the treatment temperature has been met, occlusions in the Meibomian glands of the eyelid may be expressed. The procedure may be repeated recursively until a desired level of expression has been achieved.

The present disclosure concerns a digital corneal crosslinking technology for adjusting the corneal curvature, comprising the following steps: administering in drops a composition comprising a photoinitiator compound to the corneal stromal of the subject, locally irradiating the corneal by utilizing digital micromirror device controlled by computer. The corneal curvature can be adjusted totally or locally. The invention also discloses an apparatus for the digital corneal crosslinking. The method and apparatus is minimum invasive and can be used to accurately and efficiently adjust the corneal curvature.

Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material.

Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

A surgical device and procedure are provided for performing microsurgery, including a capsulotomy of a lens capsule of an eye. The device has an elastically deformable cutting element mounted within an elastomeric suction cup. The suction cup is attached to an arm for manipulating the device. The device can be inserted into the anterior chamber of the eye, through a corneal incision, to cut a piece from the anterior portion of the lens capsule of the eye. The device is secured against the lens capsule using suction applied by one or more suction elements. The device is then removed from the eye, with the cut piece of membrane retained within the device by suction.

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 removable tip for a light energy handpiece comprises a hollow conduit configured to surround a light guide in the handpiece; a support extension having a length longer than a length of the hollow conduit; and a shielding extension coupled to the support extension at an angle less than 180 degrees and located in front of the hollow conduit. The shielding extension is configured to be inserted behind an eyelid and extend to the fornix, the shielding extension comprised of a thermally insulative material.

An ophthalmic stimulator for temporarily constricting a pupil of an eye comprises an irradiation control system, to generate an irradiation control signal, an irradiation source, coupled to the irradiation control system, to generate an irradiation, and an irradiation delivery system, coupled to the irradiation control system, to receive the irradiation from the irradiation source, and to deliver a patterned irradiation to an iris of the eye, wherein the irradiation control system controls at least one of the irradiation source and the irradiation delivery system with the irradiation control signal so that the patterned irradiation causes a temporary constriction of the pupil of the eye, without causing a permanent constriction of the pupil.

An ophthalmic treatment system and method for performing therapy on target tissue in a patient's eye. A delivery system delivers treatment light to the patient's eye and a camera captures a live image of the patient's eye. Control electronics control the delivery system, register a pre-treatment image of the patient's eye to the camera's live image (where the pre-treatment image includes a treatment template that identifies target tissue within the patient's eye), and verify whether or not the delivery system is aligned to the target tissue defined by the treatment template. The control electronics control the delivery system to project the treatment light onto the patient's eye in response to both an activation of a trigger device and the verification that the delivery system is aligned to the target tissue, as well as adjust delivery system alignment to track eye movement.

An ocular implant and a method for implanting such an ocular implant inside an eye includes an optical portion and at least two polymer haptics for fixation of the ocular implant to tissue inside an eye. At least one portion of the haptics contains a photoinitiating agent delivery component. A kit for implanting an ocular implant in an eye includes an ocular implant at least two polymer haptics; and additionally a photoinitiating agent for at least partially impregnating a first portion of the ocular element or a second portion of tissue in the eye; and, a light source for providing light of a wavelength adapted to excite the photoinitiating agent.
