A tympanostomy tube for insertion into and residence in a tympanic membrane of a mammal, is disclosed. The tympanostomy tube includes a body including a first end portion, a second end portion, a central portion dispensed between the first and second end portions. An axially extending passageway has a first open end disposed adjacent the first end portion, and a second open end disposed adjacent the second end portion, and an axis extending between the first open end and second open end. The first end portion includes a relatively enlarged diameter, generally radially extending flange. The central portion includes a reduced diameter portion sized for extending through and residing in tissue of the tympanic membrane. The second end portion includes a relatively enlarged diameter second flange disposed adjacent the second end portion. The second flange includes a perimetral edge having an incising portion sufficiently sharpened to cut as a knife through the tympanic membrane during insertion of the tympanostomy tube in the tympanic membrane.

To permit vision underwater, a contact lens has a center portion that includes underwater correction of vision and a peripheral portion that sufficiently conforms in curvature with the cornea of an eye to hold the contact lens to the eye. In one embodiment, the lens provides a correction adequate for both underwater and above water use and in another embodiment, underwater correction is provided when wet and above water correction is provided when dry.

An external module is mounted to a person and transmits energy in the light spectrum through the skin to an internal module which converts it to d.c. current with a film photocell. The d.c. current can be used to charge batteries for powering an implant without a break in the skin and to power an implant directly. Light signals can also be transmitted through the skin from an internal module to the external module to monitor implants, battery charging equipment, batteries and patient functions. Control signals can be transmitted from the external module to the internal module. The energy may be in the wavelength range of 1×10to 1×10meters and preferably in the wavelength range of 4×10to 8×10meters.
