Characterization of an optimized light source and comparison to pulsed dye laser for superficial and deep vessel clearance.

Background And Objective: An arc lamp-based device providing optimized spectrum and pulse shape was characterized and compared with two pulsed dye laser (PDL) systems using a vascular phantom. Safety and effectiveness for facial telangiectasia are presented in clinical case studies.

Study Design/materials And Methods: An optimized pulsed light source's (OPL) spectral and power output were characterized and compared with two 595 nm PDL devices.

The role of laser tunnels in laser-assisted lipolysis.

Background And Objectives: Laser-assisted lipolysis (LAL) devices are used as adjuncts to liposuction that create laser tunnels to heat the adipose and connective tissue. Available systems vary significantly across choice of wavelengths, power delivery, and tip design. Rationale are developed for optimum laser parameters evaluated with physical principles and in controlled ex vivo tests.

Semi-Automated method of analysis of horizontal histological sections of skin for objective evaluation of fractional devices.

Background And Objective: The treatment of skin with fractional devices creates columns of micro-ablation or micro-denaturation depending on the device. Since the geometric profiles of thermal damage depend on the treatment parameters or physical properties of the treated tissue, the size of these columns may vary from a few microns to a few millimeters. For objective evaluation of the damage profiles generated by fractional devices, this report describes an innovative and efficient method of processing and evaluating horizontal sections of skin using a novel software program.
