  • Publication number: 20100042082
    Abstract: Architectures and techniques for treating conditions of the eye, such as presbyopia, utilize sources of treatment energy, such as electromagnetic energy emitting devices, to implement non-corneal manipulations. According to these devices and methods, the sources of treatment energy are activated to direct energy onto parts of the eye, such as the conjunctiva and sclera, to treat presbyopia. The treatments can affect at least one property of the eye and enhance an accommodation of the eye.

  • Publication number: 20090143775
    Abstract: A method and apparatus are described for controlling temperature of a fluid used with electromagnetic energy in medical and dental laser procedures. Received fluid is passed through a heat exchanger, and heat is added to or removed from the fluid depending upon a desired effect, which may be influenced by a temperature setting. Temperature of output fluid is sensed, and heating or cooling is controlled in order to maintain output fluid temperature in a desired range. Ultraviolet radiation is used to sterilize the fluid.

  • Publication number: 20090104580
    Abstract: A fluid conditioning system is adapted to condition the fluid used in medical and dental cutting, irrigating, evacuating, cleaning, and drilling operations. The fluid may be conditioned by adding flavors, antiseptics and/or tooth whitening agents such as peroxide, medications, and pigments. In addition to the direct benefits obtained from introduction of these agents, the laser cutting properties may be varied from the selective introduction of the various agents.

  • Publication number: 20090076490
    Abstract: A fiber tip fluid output device is provided for holding a fiber tip in an electromagnetic energy cutting apparatus and for directing water particles over a radiation delivery end of the fiber tip. The fiber tip fluid output device includes a generally cylindrical body having an outer surface, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The lumen is sized and shaped to accommodate a fiber tip therethrough so that the fiber tip extends through the lumen from the proximal end to the distal end of the generally cylindrical body. The fiber tip fluid output device further includes a plurality of apertures extending around the generally cylindrical body, with each of the apertures of the plurality of apertures fluidly connecting the outer surface to the lumen. Fluid is mixed around the cylindrical body, before entering the lumen through the plurality of apertures for additional mixing.

  • Publication number: 20090031515
    Abstract: A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming.
