Detailed Description
This is a prospective randomized comparison study comparing the efficacy of micro-focused ultrasound versus fractionated carbon dioxide laser for treatment of periorbital wrinkles. Subjects who meet inclusion and exclusion criteria will be enrolled in the study. The treated sites are both lower eyelids and lateral orbits. Each side will be randomized to receive 1550nm-fractionated laser treatment on one side and the contralateral side will receive micro-focused ultrasound treatment every 6-8 weeks for a total of 2 treatments.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Fractional photothermolysis Fractional photothermolysis (FP) for treatment of photo- damaged skin is an FDA-approved method for treating facial rhytids. Fractionated treatment with 1550-nm laser is a safe, nonsurgical method for improvement of periorbital rhytides, photodamage, and scarring |
Procedure: Laser treatment
The treated sites are both lower eyelids and lateral orbits. Each side will be randomized to receive 1550nm-fractionated laser treatment on one side and the contralateral side will receive micro-focused ultrasound treatment every 6-8 weeks for a total of 2 treatments
|
| Active Comparator: High-intensity focused ultrasound High-intensity focused ultrasound (HIFUS) is an FDA-approved method for periorbital treatment and nonablative tissue tightening. Ultrasound waves induce a vibration in the tissue, generating heat and increasing the tissue temperature within a focal area. The tissue changes depend on amount of heat and exposure duration. These findings are similar to the thermally induced changes within the skin after CO2 laser fractional ablative treatments. |
Procedure: Laser treatment
The treated sites are both lower eyelids and lateral orbits. Each side will be randomized to receive 1550nm-fractionated laser treatment on one side and the contralateral side will receive micro-focused ultrasound treatment every 6-8 weeks for a total of 2 treatments

Outcome Measures
Primary Outcome Measures
- Global Improvement Scale [3 months]
Global improvement scale score, as a percent improvement from baseline to 1 and 3 months, respectively, after treatment. Two non-treating dermatologists will independently blindly evaluate the photographs at baseline, 1 and 3 months after treatment; differences will be resolved via a forced agreement process.
- Quantitative eyelid laxity scale [3 months]
Two non-treating dermatologists will independently blindly evaluate the photographs at baseline, 1 and 3 months after treatment; differences will be resolved via a forced agreement process.
Secondary Outcome Measures
- Subject Satisfaction [10 years]
Subject satisfaction will be determined by a satisfaction questionnaire, and subjects will be asked to select the treatment side they preferred
- Adverse events [10 years]
Any adverse events related to the use of the fractionated laser and ultrasound-tightening device (e.g. infection, prolonged erythema, prolonged edema, bleeding, ulceration, erosion or pigmentation) will be recorded.
