20190307551 · 2019-10-10 ·

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.

Posterior capsulotomy using laser techniques

A system and method are provided for removing a natural lens and inserting an Intraocular Lens (IOL) into the lens capsule of an eye. Specifically, this is accomplished by inserting the IOL through an opening on the posterior capsule that is created using a focused laser beam. The system includes a laser unit, a detector for creating images of the interior of the eye, and a computer that controls the cooperative functions of the detector and the laser unit. Based on images of the posterior capsule provided by the detector, the computer is used to control movements of the focal point through tissue of the posterior capsule to perform Laser Induced Optical Breakdown (LIOB) on posterior capsule tissue. The result is a laser capsulotomy that creates an opening through the posterior capsule allowing the natural lens to be removed and the IOL to be implanted.

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, wherein the implant is cross-linked so as to prevent an immune response to the implant and/or rejection of the implant by the patient; and (iv) covering the cross-linked implant with the flap, the cross-linked implant being surrounded entirely by the stromal tissue of the cornea.

Ophthalmic range finding
10390996 · 2019-08-27 · ·

Embodiments of the invention provide methods and systems for analyzing the ophthalmic anatomy of a patient posterior to the cornea. The method may include scanning a focus of a femtosecond laser beam along a path within the patient's eye. A portion of the path may be disposed posterior to the patient's cornea. The method may also include acquiring a first reflectance image and a second reflectance image associated with the focus disposed respectively at a first location of the path and a second location of the path. The method may further include determining the presence or absence of an ophthalmic anatomical feature of the eye based on a comparison between the first reflectance image and the second reflectance image.

Methods For Treatment Of Dry Eye And Other Acute Or Chronic Inflammatory Processes
20190247227 · 2019-08-15 ·

Methods for treatment of dry eye and other acute or chronic inflammatory processes are disclosed herein. One method includes administering a drug delivery implant to a patient in need thereof, the drug delivery implant comprising one or more Rock inhibitors and/or one or more Wnt inhibitors, the patient having a medical condition selected from the group consisting of dry eye, lichen planus, arthritis, psoriasis, plantar fasciitis, pars planitis, scleritis, keratitis, chronic meibomian gland inflammation, optic nerve neuritis, uveitis, papillitis, diabetic neural pain, diabetic retinopathy, a cataract, a side effect occurring after refractive surgery, a side effect occurring after corneal transplant, a side effect occurring after retinal detachment surgery, and combinations thereof. The administration of the drug delivery implant to the patient treats the medical condition, reduces the symptoms associated with the medical condition, enhances nerve regeneration, and/or alleviates the medical condition.

Intracorneal Lens Implantation With A Cross-Linked Cornea
20190247181 · 2019-08-15 ·

A method of intracorneal lens implantation with a cross-linked cornea is disclosed herein. The method includes forming a pocket in a cornea of an eye, applying a photosensitizer inside the pocket so that the photosensitizer permeates at least a portion of the tissue bounding the pocket, the photosensitizer facilitating cross-linking of the tissue bounding the pocket; irradiating the cornea so as to activate cross-linkers in the portion of the tissue bounding the pocket, and thereby kill cells therein; inserting a lens implant into the pocket; and applying laser energy to the lens implant in the pocket using a laser so as to correct refractive errors of the lens implant and/or the eye in a non-invasive manner. In other embodiments, a lens implant is soaked in a cross-linking solution that includes a photosensitizer prior to being inserted into the pocket in the cornea of an eye.

Cornea transplantation
10362937 · 2019-07-30 · ·

A planning device generating control data for a treatment apparatus for cornea transplantation using a laser device to separate a corneal volume by at least one cut surface in the cornea and to separate a transplant, from a surrounding transplantation material by at least one cut surface, wherein the planning device includes an interface supplying measurement data relating to parameters of the cornea. A computer defines a corneal cut surface which confines the corneal volume to be removed, and determines a transplant cut surface by using the transplantation material data and depending on the defined corneal cut surface. The transplant cut surface confines the transplant, and the computer generates one control data for each cut surface to control the laser, wherein the respective cut surfaces can be produced by the laser to isolate the corneal volume and the transplant and to make them removable.
