Abstract: The present invention relates to a single and/or dual laser delivery system attached to an existing ophthalmic operating microscope, comprising of a single and/or dual wavelength laser unit [1]; and a delivery system [5]. The laser unit [1] comprises of a green laser module 532 nm [3] and a yellow laser module 577 nm [4] along with an aiming beam [7] 635 nm. The delivery system comprises of a right-angle prism [5A]: X and Y Galvo assembly [5B] and a focusing lens assembly [5C]. The laser unit passes through a fiber optic cable [6] gets reflected using the right angle prism, gets deflected by the Galvo assembly, enters the focusing lens assembly and gets reflected by a folding mirror [5D] and focused on human eye capsule. The system converges and focuses the laser wavelengths in line with the aiming beam to create a circular pattern to accomplish a pre-measured Capsulorhexis.

Abstract: A laser eye surgery system focuses light along a beam path to a focal point having a location within a lens of the eye. The refractive index of the lens is determined in response to the location. The lens comprises a surface adjacent a second material having a second refractive index. The beam path extends a distance from the surface to the focal point. The index is determined in response to the distances from the surface to the targeted focal point and from the surface to the actual focal point, which corresponds to a location of a peak intensity of an optical interference signal of the focused light within the lens. The determined refractive index is mapped to a region in the lens, and may be used to generate a gradient index profile of the lens to more accurately place laser beam pulses for incisions.

Abstract: 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.

Abstract: Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL) that has a non-zero residual spherical error that requires an estimated diffractive power addition in the IOL. In some embodiments, a plurality of laser pulses are applied to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, the estimated diffractive power addition to correct for the residual spherical error.

Abstract: 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.

Abstract: A method for modifying the refractive index of an optical polymeric material. The method comprises continuously irradiating predetermined regions of an optical, polymeric material with femtosecond laser pulses to form a gradient index refractive structure within the material. The optical polymeric material can include a photosensitizer to increase the photoefficiency of the two-photo process resulting in the formation of the observed refractive structures. An optical device includes an optical, polymeric lens material having an anterior surface and posterior surface and an optical axis intersecting the surfaces and at least one laser-modified, GRIN layer disposed between the anterior surface and the posterior surface and arranged along a first axis 45° to 90° to the optical axis. The at least one laser-modified GRIN layer comprises a plurality of adjacent refractive segments characterized by a variation in index of refraction across at least one of at least a portion of the adjacent segments and along each segment.

Abstract: A method for adjusting the refractive power of a fluid-filled intraocular lens implanted into a patient's eye. The method comprises selecting a pattern to cause a flattening of the intraocular lens or an increase in curvature of the intraocular lens, and ablating the pattern, onto either an optical element of the intraocular lens or a flexible element of the intraocular lens, to alter either one or both of a refractive power and an amplitude of accommodation of the intraocular lens. The ablating occurs while the intraocular lens remains implanted in the patient's eye. The ablating maintains the integrity of a fluid-filled interior cavity defined between the optical element and the flexible element, but causes the flattening of the intraocular lens or the increase in curvature of the intraocular lens.

Abstract: An ophthalmological laser therapy device having a pulsed laser, a positioning system and a control system that produce incisions in a tissue of an eye, in particular for producing corneal access incisions and a corresponding method. The invention produces corneal access incisions having increased leak tightness under external influences. Compressive strength, and complex incision geometries can be realized. An ophthalmological laser therapy device has a control system which is programmed to vary the operating parameters of the laser system and/or of the positioning system on the basis of a local position of the focal volume of a laser beam in the corneal tissue such that the access incision in the corneal tissue is varied and/or interrupted in the width of the access incision. The invention further includes a corresponding computer program product and a method for performing a corneal access incision in a corneal tissue of an eye.
