Prospective study on combination diode laser and radiofrequency energies (ELOS) for the treatment of leg veins.

OBJECTIVE

To evaluate the Polaris LV, electro-optical synergy (ELOS) technology, which combines diode laser (915 nm) and radiofrequency (RF) (1 MHz) energies, for the treatment of leg veins.

METHODS

A total of 25 patients (Fitzpatrick I-IV) with a total of 35 sites (0.3-5.0 mm vessel diameters) were treated with up to three sessions at 4- to 10-week intervals. Polaris LV settings included: 80-140 J/cm(2) of laser light, 80-100 J/cm(3) of conducted RF, and pulses of 100-300 ms. Vessel clearance was graded by both the treating and an independent physician.

RESULTS

At 1 and 6 months after the final treatment, approximately 77% of treatment sites exhibited 75-100% vessel clearance, and 90% had 50-100% vessel clearance. No treatment sites had less than 25% vessel clearance. Transient dyschromic side effects were common.

CONCLUSIONS

The Polaris LV ELOS system is effective and safe in treating leg veins, including telangiectases, venulectases, and reticular veins.
