  • Patent number: 10350111
    Abstract: A system for corneal treatment includes a light source that activates cross-linking in at least one selected region of a cornea treated with a cross-linking agent. The light source delivers photoactivating light to the at least one selected region of the cornea according to a set of parameters. The system includes a controller that receives input relating to the cross-linking agent and the set of parameters. The controller includes computer-readable storage media storing: (A) program instructions for determining cross-linking resulting from reactions involving ROS including at least peroxides, superoxides, and hydroxyl radicals, and (B) program instructions for determining cross-linking from reactions not involving oxygen. The controller executes the program instructions to output a calculated amount of cross-linking in the at least one selected region of the cornea. In response to the calculated amount of cross-linking, the light source adjusts at least one value in the set of parameters.

  • Patent number: 10238540
    Abstract: Embodiments of the invention provide systems for treating the retina and/or other areas of a patient's eye. The procedures may involve using one or more treatment beams (e.g., lasers) to cause photocoagulation or laser coagulation to finely cauterize ocular blood vessels and/or prevent blood vessel growth to induce one or more therapeutic benefits. In other embodiments, a series of short duration light pulses (e.g., between 5-15 microseconds) may be delivered to the retinal tissue with a thermal relaxation time delay between the pulse to limit the temperature rise of the target retinal tissue and thereby limit a thermal effect to only the retinal pigment epithelial layer. Such procedures may be used to treat diabetic retinopathy, macular edema, and/or other conditions of the eye. The treatment beam may be delivered within a treatment boundary or pattern defined on the retina of the patient's eye.

  • Patent number: 9913678
    Abstract: Embodiments include methods, apparatuses, and systems for reducing elevated intraocular pressure (IOP) in a patient to either prevent or treat open-angle glaucoma. Heat is applied to the trabecular meshwork in the patient's eye without damaging proteins in the trabecular meshwork. The application of heat to the trabecular meshwork has the effect of relaxing or loosening protein clogs or other inhibitors in the trabecular meshwork, which are either reducing or obstructing of the outflow of aqueous humor, thereby increasing the patient's IOP and causing ocular hypertension (OHT). By loosening or relaxing clogs or other inhibitors in the trabecular meshwork, the outflow path for aqueous humor is increased or restored, which can lower IOP and either prevent or treat glaucoma. Force may also be applied to the patient's eye to apply pressure to the trabecular meshwork to further assist in the loosening or relaxing of clogs or other inhibitors in the trabecular meshwork.

  • Patent number: 9789003
    Abstract: An apparatus for treatment of an eye comprises a source of pulsed laser radiation, and a control device for controlling a focus of the laser radiation to generate an incision figure. The incision figure defines a corneal flap, a first auxiliary channel and a second auxiliary channel. The corneal flap is connected to adjoining corneal tissue in a hinge region, and has a flap underside parted-off from adjoining corneal tissue by a bed incision. The first auxiliary channel extends from the hinge region to an outer surface of the eye and is adapted to remove gases that develop during the generation of the bed incision. The second auxiliary channel extends along an edge of the bed incision, is connected to the first auxiliary channel, and extends beyond the hinge region. The control device is configured to generate the second auxiliary channel prior to the bed incision.

  • Patent number: 9784966
    Abstract: The present invention relates to a deformable mirror, specifically a gimbaled deformable mirror for use with wavefront sensors, which mirror separates the tilt correction from the higher order modes (e.g. defocus, spherical, astigmatism, and coma at higher order aberrations, up to the limits of a particular mirror design) in order to use all of the available mirror deformation stroke for correcting the higher order modes. The separation is done by placing the deformable mirror in a gimbaled structure, so that the deformable mirror can be tilted in two independent, orthogonal axes.

    Abstract: Systems and methods related to corneal ablation for treatment of one or more high-order optical aberrations are provided. A method includes providing a defect-correcting prescription, determining an ablation profile to impose the prescription on the cornea, and determining a sequence of laser-energy ablations to impose the ablation profile on the cornea. The prescription may include a high-order optical correction. The ablation profile includes a first-segment profile and a second-segment profile. The second-segment profile corresponds to at least one high-order optical correction. The ablation sequence includes applying ablations corresponding to the first-segment profile prior to applying ablations corresponding to the second-segment profile.

  • Patent number: 9724240
    Abstract: This apparatus treats the lens capsule so as to increase accommodation of the eye. The treatment of the lens capsule may comprise treating a portion of the lens capsule so as to stiffen the treated portion and improve accommodation of the eye. The intermediate portion of the lens capsule may be located between an optically used central portion of the lens capsule and a peripheral portion of the lens capsule connected to zonules of the eye. The stiffened intermediate portion of the lens capsule can improve coupling of the peripheral portion of the lens capsule to the central portion of the lens capsule, such that an amount of accommodation of the optically used central portion of the lens is increased. As the force of the lens capsule to a lens disposed within the lens capsule is increased, the lens may comprise the natural lens of the eye or an artificial lens such as an accommodative IOL.
