  • Publication number: 20190224497
    Abstract: A method of treating dry eye includes delivering light energy from outside an eyelid toward the eyelid, and maintaining the delivery of the light energy toward the eyelid for a period of time to soften an obstruction of at least one meibomian gland. The light energy may be delivered specifically to the obstruction in the at least one meibomian gland without physically contacting the at least one meibomian gland, or the light energy delivered toward the eyelid may conductively apply heat to the meibomian gland to melt the obstruction. A corresponding apparatus includes a light energy source positionable outside an eyelid and configured to deliver the light energy from outside an eyelid toward the eyelid, and a controller configured to control the light energy source to maintain the delivery of the light energy toward the eyelid for a period of time to soften the obstruction.

  • Publication number: 20190060158
    Abstract: An apparatus providing heat for treatment of an eyelid includes a heater unit configured to apply heat directly to an outer surface of the eyelid when an electrical signal is applied to the heater unit. The heater unit is affixed directly to the outer surface of the eyelid using an adhesive. A temperature regulator applies the electrical signal to the heater unit in order to achieve heating of the outer surface of the eyelid to a specified temperature range. A method is also disclosed that comprises affixing a heater unit directly into contact with the outer surface of the eyelid using an the adhesive. A control signal is applied to the heater unit to generate heat to the outer surface of the eyelid and is maintained for a period of time until the outer surface of the eyelid is heated to a specified temperature range.

  • Publication number: 20190000610
    Abstract: Intraocular lenses and related assemblies and intraocular attachment methods are disclosed herein. In one embodiment, an intraocular lens assembly comprises a helical-shaped coil fastener to affix an intraocular lens to an iris to correct for astigmatism, presbyopia, and/or myopia or hyperopia. The helical-shaped coil fastener comprises a head and a helical wire extending from a bottom surface of the head and comprising a pointed tip opposite the head. The helical-shaped coil fastener is configured to be affixed to the iris by rotatable penetration of the iris, and thus can be removed from the iris by reverse rotation of the helical-shaped coil fastener. The helical-shaped coil fastener has a low volume, large surface area, low cross-sectional area of penetration, and an oblique angle of penetration. Thus, the helical-shaped coil fastener is easy to apply, easy to remove, minimizes tissue damage, maximizes stability, and minimizes penetration force.

  • 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: 9216028
    Abstract: In one embodiment, an apparatus for treating mammalian meibomian glands involves clearing the meibomian glands. The apparatus comprises a heater configured to apply a regulated heat to an eyelid containing the meibomian glands to a temperature adequate to melt obstructions in the meibomian glands to put the obstructions in a fluid or suspension (melted) state, and a controller maintaining the heat for a time period adequate to melt the obstructions. The glands can then be mechanically treated by a mechanical treatment applicator to express fluid from the glands by using a compressive force, wherein the treating is carried out either during the time period or after the time period but while the obstruction remains in a fluid state. Subsequent pharmacological treatment of the glands by use a pharmacological agent (topical or systemic) can then be used to assist in maintaining proper flow of lipids from the glands.

  • Publication number: 20150157347
    Abstract: In accordance with certain illustrative embodiments, methods and apparatuses of treating obstructive disorders of the structure of an eye or eyelid are disclosed. The treating may involve applying heat to the structure containing the obstructive disorder to melt an obstruction in the structure and place the obstruction in a melted state. The heat may be maintained for a time period to melt the obstruction and place the obstruction in the melted state. The structure may be treated by expressing the melted obstruction from the structure. The treating may be carried out either during the time period or after the time period when heat is applied but while the obstruction is in the melted state. In certain embodiments, the method further involves subsequently treating the structure by use of a pharmacological agent.
