Abstract:
A method for treating presbyopia utilizes an Erbium based, pulsed laser to sever sub-conjunctival strictures located within the scleral matrix of the eye. Introduction of treatment energy into the scleral matrix increases or facilitates an increase in accommodation, thereby mitigating the effects of presbyopia. The treatment energy can be directed into the scleral matrix to form tunnel ablations in and through the strictures of the scleral matrix. The tunnel ablations can enhance the accommodation of the patient's eye, enabling the eye to refocus at near distances while not losing its ability to focus at a distance.

The distal end of the illumination device is illustrated as a unitary structure, and the proximal end is illustrated as having multiple proximal end members. The illumination device includes two or more optical fibers for transmitting energy toward the distal end, and at least one optical fiber for transmitting energy from the distal end toward the proximal end of the device.
Abstract:
Output optical energy pulses including relatively high energy magnitudes at the beginning of each pulse are disclosed. As a result of the relatively high energy magnitudes which lead each pulse, the leading edge of each pulse includes a relatively large slope. This slope is preferably greater than or equal to 5. Additionally, the full-width half-max value of the output optical energy distributions are between .025 and 250 microseconds and, more preferably, are about 70 microseconds. A flashlamp (41) is used to drive the laser system, and a current is used to drive the flashlamp. A flashlamp current generating circuit (30) includes a solid core inductor (39) which has an inductance of 50 microhenries and a capacitor (35) which has a capacitance of 50 microfarads.

Abstract:
An endodontic probe is used to perform disinfection procedures on target tissues within root canal passages and tubules. The endodontic probe can include an electromagnetic radiation emitting fiber optic tip having a distal end and a radiation emitting region disposed proximally of the distal end. According to one aspect, the endodontic probe can include a porous structure that encompasses a region of the fiber optic tip excluding the radiation emitting region and that is loaded with biologically- active particles, cleaning particles, biologically-active agents, or cleaning agents for delivery from the porous structure onto the target tissues. Another aspect can include provision of the endodontic probe with an adjustable channel-depth indicator, which encompasses a region of the fiber optic tip besides the radiation emitting region and which is movable in proximal and distal directions along a surface of the fiber optic tip to facilitate the provision of depth-of-insertion information to users of the endodontic probe.
Abstract:
A high power source of electro-magnetic radiation having a multi-purpose housing is disclosed. The multi-purpose housing includes an interior filled with a material forming at least a light source and further comprising a reflector which can envelope a laser rod surrounded by light sources for providing light excitation to the laser rod. A material defining outer surfaces of the light sources extends out to and defines outer surfaces of the reflector. A high-reflectivity coating is disposed over an outer surface of the reflector, as is a protective coating. Also disposed over an outer surface of the reflector can he an optional heat sink, with cooling being performed by an optional arrangement of forced-air traveling over the heat sink. The light sources may be light source pumps, and the high-reflectivity coating may be formed to envelop the reflector.
