  • Patent number: 8950405
    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. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

  • Publication number: 20140066821
    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: 8632578
    Abstract: A system for treating meibomian gland dysfunction comprising a heating element that applies heat to the tissue proximate the patient's meibomian glands to provide conductive heat transfer to the meibomian glands, which assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force application device may also apply force to tissue proximate the patient's meibomian glands during the application of heat to improve conductive heat transfer and reduce blood flow in tissue that causes convective heat loss, and to help express obstructions from the meibomian gland, including from a channel of the meibomian gland, with reduced discomfort to the patient. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands.

  • Patent number: 8617229
    Abstract: A system for treating meibomian gland dysfunction comprising a heating element that applies heat to the outside of the eyelid to provide conductive heat transfer to the meibomian glands, which assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force application device may also apply force to the patient's eyelid during the application of heat to improve conductive heat transfer and reduce blood flow in the eyelid that causes convective heat loss, and to help express obstructions from the meibomian gland, including from a channel of the meibomian gland. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands while reducing the amount of time to reach desired temperature levels and/or aid in reducing discomfort to the patient during treatment.

  • Patent number: 8600484
    Abstract: A method of evaluating dry eye in humans wherein the flow of naturally occurring secretion to the eye is reduced or stopped due to the presence of an obstruction of a meibomian gland in the eyelid involves applying a pressure to the eyelid that mimics pressure applied during blinking; and simultaneously imaging the glands to diagnose the condition of the meibomian gland. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

  • Publication number: 20130053733
    Abstract: A method of treating meibomian gland dysfunction is disclosed. The method includes directing RF energy to an internal portion of a meibomian gland, selectively targeting an obstruction within a duct of the meibomian gland with the applied RF energy to melt, loosen, or soften the obstruction, and expressing the obstruction from the duct of the meibomian gland. An apparatus for treating meibomian gland dysfunction is also disclosed. The apparatus comprises at least one RF electrode configured to direct RF energy to an internal portion of a meibomian gland located in an eyelid of an eye, the at least one RF electrode further configured to selectively target an obstruction within a duct of the meibomian gland with the applied RF energy to melt, loosen, or soften the obstruction. The apparatus also comprises at least one expressor configured to express the obstruction from the duct of the meibomian gland.

  • Publication number: 20120143102
    Abstract: A system for treating meibomian gland dysfunction. A controller controls heat applied to the tissue proximate the patient's meibomian glands to provide conductive heat transfer to the meibomian glands. The application of heat assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force is also applied to tissue proximate the patient's meibomian glands during the application of heat to improve conductive heat transfer and reduce blood flow in tissue that causes convective heat loss. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands. Reducing the amount of time to reached desired temperature levels an aid in reducing discomfort to the patient during treatment.
