Abstract
Background and Objectives
Electro‐optical synergy (ELOS™) is a novel technology that combines radiofrequency (RF) with optical energy. This study investigated the safety and effectiveness of the Polaris LV™ system, which is based on combined RF and diode laser (915 nm), for the treatment of leg veins.
Study Design/Materials and Methods
Fifty women (Fitzpatrick II–IV) with red or blue leg veins (1–4 mm in diameter) were treated with the Polaris LV, using a fluence of 60–80 J/cm^2^ and conducted RF energy of 100 J/cm^3^. Patients received up to three treatment sessions at 2‐ to 4‐week intervals. Both patients and an independent physician graded the level of vessel clearance at 2 months following the last treatment, using pre‐ and post‐treatment photographs. Also, a computer‐generated assessment of vessel clearance was done in 40 patients. Twenty patients provided biopsy specimens for histologic assessment.
Results
Approximately three‐quarters of patients demonstrated ≥ 50% vessel clearance, and about 30% had 75%–100% vessel clearance. Computer‐generated scores correlated closely with physician scores. Histologic assessment showed signs of coagulation and prominent endothelial degeneration in all treated vessels, but the epidermis remained normal. There were minimal complications.
Conclusions
The Polaris LV is effective and safe in treating red and blue leg veins up to 4 mm in diameter. © 2005 Wiley‐Liss, Inc.
