  • Patent number: 10980413
    Abstract: Embodiments disclosed herein include devices, systems, and methods for determining tear film break-up time and for detecting eyelid margin contact and blink rates, particularly for diagnosing, measuring, and/or analyzing dry eye conditions and symptoms. The apparatus and methods for determining tear film break-up time and for detecting eyelid margin contact and blink rates, particularly for diagnosing, measuring, and/or analyzing dry eye conditions and symptoms may employ ocular surface interferometry (OSI) devices or other imaging and display devices capable of imaging and displaying a picture of a patient's eye during tear film break-up time and blink rate related procedures.

  • Patent number: 10940074
    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.

  • Patent number: 10905898
    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: 20200315778
    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.
