The purpose of this study is to evaluate the safety and effectiveness of a new laser for the removal of unsightly spider veins on the legs. The device used in this study is the Cutera Excel V laser, which is a dual wavelength 532 nm potassium titanyl phosphate (KTP) and 1064 nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser. The Excel V laser has received 510(k) clearance from the FDA, which means the FDA has approved the laser for dermatological and vascular conditions, like spider veins.

Primary | Mean Improvement of Lower Extremity Spider Veins Based on Blinded Photo Assessments | A panel of independent physicians will assess before and after digital photographs of each treated area. The physicians will be blinded to the treatment parameters and to the temporal order of the before and after photographs. Each independent physician will be asked to select the baseline photograph for each treated area and then rate the degree of improvement using the following scale: 0 = No Improvement (0%) 1 = Mild Improvement (< 25%) 2 = Moderate Improvement (26 to 50%) 3 = Significant Improvement (51 to 75%) 4 = Very Significant Improvement (76 to 100%) |
24 weeks (12 weeks post-final laser treatment) | No |
Secondary | Mean Improvement of Lower Extremity Spider Veins Based on Blinded Photo Assessments | The panel of independent physicians will be asked to select the baseline photograph for each treated area and then rate the degree of improvement using the following scale: 0 = No Improvement (0%) 1 = Mild Improvement (< 25%) 2 = Moderate Improvement (26 to 50%) 3 = Significant Improvement (51 to 75%) 4 = Very Significant Improvement (76 to 100%) |
12 weeks (post-1st laser treatment) | No |
Secondary | Percent of Subjects With "Significant" or "Very Significant" Improvement in Lower Extremity Spider Veins, as Assessed by the Treating Investigator. | The Investigator will perform the Physician's Global Assessment of the degree of improvement for each treated area of the subject's lower extremity spider veins using the following scale: 0 = No Improvement (0%) 1 = Mild Improvement (< 25%) 2 = Moderate Improvement (26 to 50%) 3 = Significant Improvement (51 to 75%) 4 = Very Significant Improvement (76 to 100%) |
24 weeks (12 weeks post-final laser treatment) | No |
Secondary | Percent of Subjects With "Significant" to "Very Significant" Improvement of Lower Extremity Spider Veins, as Assessed by Subject. | Subjects will be asked to rate the improvement of each treated area of their lower extremity spider veins as compared to baseline using the following scale: 0 = No Improvement (0%) 1 = Mild Improvement (< 25%) 2 = Moderate Improvement (26 to 50%) 3 = Significant Improvement (51 to 75%) 4 = Very Significant Improvement (76 to 100%) |
24 weeks (12 weeks post-final laser treatment) | No |
Secondary | Percent of Subjects Satisfied With Improvement of Treated Spider Veins. | Subjects will assess their satisfaction with the procedure and with the improvement in lower extremity spider veins at twelve weeks post final laser treatment based using the following scale: 1 = Very Much Not Satisfied 2 = Not Satisfied 3 = Somewhat Satisfied 4 = Satisfied 5 = Very Much Satisfied |
24 weeks (12 weeks post-final laser treatment) | No |
Secondary | Mean Pain Score Associated With Laser Treatment. | Subjects will be asked to rate the average pain experienced during laser treatments using the 0-10 numeric pain rating scale (0 = no pain to 10 = worst possible pain). | Day 0 (1st laser treatment) | Yes |
Secondary | Mean Pain Score Associated With Laser Treatment | Subjects will be asked to rate the average pain experienced during laser treatments using the 0-10 numeric pain rating scale (0 = no pain to 10 = worst possible pain). | 12 weeks (2nd laser treatment) | Yes |
