Pulsed dye laser treatment of XXXX : a randomized clinical pilot study comparison of 607- and 595-nm wavelength lasers.

@entity1 @entity66 @entity158
BACKGROUND: The 595-nm pulsed dye laser has been used for the treatment of benign epidermal @entity66 (EPLs), but there is a risk of inducing undesirable purpura with treatment. OBJECTIVE: To compare a 607-nm laser with a commercially-available 595-nm laser for the treatment of EPLs. MATERIALS AND METHODS: Monte-Carlo simulations were performed to characterize laser interaction with skin. Ten @entity1 with EPLs were treated with a 607-nm study prototype laser and the 595-nm pulsed dye laser twice at 2- to 4-week intervals on the left or right side on a randomized basis. Study endpoints included clearance rate of lesions, side effects immediately after treatment and at final follow-up, and @entity1 discomfort/ @entity158 . RESULTS: Monte-Carlo simulations show that the 607-nm is absorbed more specifically by melanin than the 595-nm wavelength. Both lasers were effective in treatment of EPLs. The average degree of improvement overall was 41.2% with the 607-nm laser and 40% with the 595-nm laser. @entity1 reported less discomfort/ @entity158 during treatment with the 607-nm laser. CONCLUSIONS: Our findings suggest that the 607-nm laser is safe and at least as effective as the 595-nm laser in treatment of EPLs. There was less @entity1 discomfort/ @entity158 during treatment using the 607-nm laser.
