Abstract:

Introduction: By introducing of laser systems and their continuous development, a new chapter of laser systems applications in a variety fields including research and clinical science in addition to the therapeutic, diagnostic applications were available for medical professionals in various fields. Most lasers emit radiation with intrinsic probable risks where in laser-tissue interactions based on special mechanisms most important ones including photothermal, photochemical, photoablative and photomechanical, may causes potential risks and damage, similar to other side effects of thermal, chemical and mechanical in biological targets. Materials and Methods Each of these damage mechanisms are based on multitude laser irradiation parameters including wavelength pulse duration, irradiation time, power and energy density. Results Based on the optimized selection of the irradiation parameters and the type of the biological tissue, preliminary side effects in skin and eye organs can be prevented Conclusion Then, it is crucial to notify laser safety considerations especially in clinical applications for both patients and operators for preventing or reducing the possible damages

Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a ...
