Abstract: Certain aspects of the present disclosure are directed to a system for treating a gland of a patient. The system includes a handheld device including a probe, a tip of the probe being formed with a suction opening and a delivery opening; a backend apparatus including a fluid reservoir configured to contain a fluid, an agent reservoir configured to contain agent particles, and a suction force generator; a delivery channel in fluid communication with the delivery opening and the fluid reservoir and the agent reservoir, the delivery channel allowing a mixture of the fluid and the agent particles to travel through the delivery channel and exit at the delivery opening; and a suction channel in fluid communication with the suction opening and the suction force generator, the suction channel allowing a suction force being generated at the suction opening by the suction force generator.

Abstract: A low-version reader (LVR) includes a frame adapted to be worn by a person as well as first and second light sources supported by the frame and positioned to project light beams focusing on a working surface. The LVR also includes a first battery embedded in the frame and a first power-supply circuit that regulates power provided by the first battery to energize the first light source. The first battery is rechargeable and in electrical communication through a first discharge path with the first light source. The first discharge path allows the first battery to energize the first light source. A first charger receptacle in electrical communication through a first charge path with the first battery. The first charge path allows charging the first battery when a power charger is coupled with the first charger receptacle.

Abstract: Lighted reading glasses for individuals with low vision. In one embodiment, the reading glasses include a frame for supporting lenses having an oculus dexter side and an oculus sinister side, at least one oculus dexter lens supported by the frame on the oculus dexter side, and at least one oculus sinister lens supported by the frame on the oculus sinister side, each of the at least one oculus dexter lens and the at least one sinister lens having an induced prism in a range between about 4 PD and about 22 PD and a lens power that is greater than about +4.00 diopters and less than about +20.00 diopters such that each of said lenses focuses at a distance that is greater than about 5 cm and less than about 25 cm, and at least one light source having a predetermined light strength oriented to project light to provide a predetermined lighted area in a predetermined field.
