White Paper: Cruzy Tagger (M.D.) and Inna Belenky (Ph.D.)

Introduction: The 1064 nm Neodymium-YAG laser have been widely used for hair removal, treatment of vascular lesions, skin photo-rejuvenation and more. Development of the long pulsed Nd:YAG technology has enabled delivery of macropulses, consisting of a series of synchronized sub-pulses which is believed to decrease the collateral thermal. The aim of this study was to investigate the safety and efficacy of Pulse ConfiguRhythm (PCR™) technology with both Single and Multiple pulse configurations as incorporated in Viora’s V-Nd:YAG handpiece. Materials and Methods: A group of 31 volunteer patients were treated with the V-Nd:YAG handpiece which also incorporates changeable spots and integrated contact cooling. 26 of the patients were treated for a range of vascular lesions, 2 patients for facial photo-rejuvenation and 3 patients for long-term hair removal. Clinical photographic assessments were recorded in two phases and the treating practitioners were asked to record and immediately report any adverse or unexpected side-effects. Results: Visual assessment for each patient treated for vascular lesions showed total clearance of the vessel without reappearance for up to 10 months. Superficial cherry hemangioma cleared after a single treatment and deeper lesions after 2 treatments. Response to the hair reduction treatment occurred 4 weeks after the first treatment. Facial photo-rejuvenation treatments yielded general skin texture and tone improvement, as well as a noticeable skin tightening effect of the wrinkles. Discussion and Conclusion: The Viora long pulse Nd:YAG laser with variable-pulse duration, Single and Multiple pulse configurations, changeable spots and contact cooling achieved remarkable results. There was notable clearing of the treated vascular lesions, with selective damage of the vascular lesions without significant discomfort or non-selective damage to the surrounding tissue. In conclusion, the final results of the selected patients, expressed in effective and comfortable treatment modality with minimal side effects.
