Book Description
A comparison between the effects of single and multiple laser pulse-trains of equivalent energy was performed. Visual evoked potentials (VEPS) recorded bipolarly from the visual cortex of two rhesus monkeys in response to a counterphasing grating were used to assess the magnitude of the visual loss following four types of exposures: single and multiple pulses with total energies equal to 50% and 500% of the maximum permissible exposure (MPE) standard for humans. The results showed that the effects of a series of laser flashes presented within 200ms are similar to those of a single laser flash whose energy is equivalent to the cumulative energy of the multiple-pulse exposure. Keywords include: Flashblindness; Laser radiobiology; Multiple pulse; Q-switched; Radiation effects; Rhesus monkey; Visual evoked potential.

Book Description
Rapid technical developments with lasers and other energy devices have continued over recent years, both in the different types of devices available and in what can be used for cosmetic and other treatments, including scar and tattoo removal, hair removal, cellulite, and lipolysis. In the second edition of Lasers and Energy Devices for the Skin, the top practitioners in the field have pooled their expertise to offer a broad and balanced perspective. Updated to encompass the latest refinements in the field, this volume: Explores the latest techniques in laser hair removal and scar removal Reviews advances in antiaging techniques for the skin of the face Covers the use of photodynamic therapy for skin tumors, psoriasis, localized scleroderma, viral warts, onichimycosis, and more Reviews currently available and novel approaches for noninvasive and intended selective destruction of fat Highlights the risks of pigmentary alterations and scarring following procedures on Asian skin Covers advances in liposuction brought about by the advent of tumescent anesthesia The book also discusses pain management during laser surgery and laser treatments and includes coverage of the importance of complying with safety standards, potential unsafe practices, and potential medicolegal problems. Providing the understanding needed to develop creative ways to use light-based technologies, the book gives readers easy access to practical treatment parameters.
