Example text

The temperature of the blood vessel is elevated to over 60°C for approximately 1 millisecond (the pulse duration of the laser), which results in blood vessel endothelial contraction. The surrounding tissue is not heated because the laser pulse duration has been tailored to be close to the thermal relaxation time of the blood vessel. over, the light energy should be further shifted to the red range, close to 595 nm. For this purpose, the PhotoDerm flashlamp (ESC Sharplan, Norwood, MA) produces a 595-nm beam of light with a pulse duration of up to 30 milliseconds.

These fluences are attained with collimated beams that are 3 to 5 mm in diameter. 5 J͞cm2, as compared with 5 J͞cm2 for a CO2 laser. 14,15 An important difference between Er:YAG and CO2 laser-tissue interactions is the consistency of vaporization depth for multilayer treatment. I 20 7/7/00 7:18 AM Page 20 BASIC LASER SCIENCE thermolysis involves absorption of specific wavelengths of light energy by chromophores in tissue. The chromophores in vascular lesions are hemoglobin and oxyhemoglobin, which selectively absorb wavelength-specific light in the range of about 500 to 1000 nm.

Thus, even though the intense pulsed light (IPL) sources are considered class-II medical devices by the FDA, as are lasers, they are not categorized in the CDRH laser classification scheme. As a result, there has been much confusion about the safety of IPL devices as compared with true laser systems. For example, lasers require eye protection, whereas eye protection is only recommended for IPL sources. Furthermore, the states that have ruled on the issue of who can legally treat have only referred to lasers in their rulings thus far.
