Continuous Wave Fractional CO Laser for the Treatment of Upper Eyelid Dermatochalasis and Periorbital Rejuvenation.

Fractional continuous wave CO laser resurfacing is used to improve photodamage, wrinkles, and acne scarring by surface ablation and by using heat to activate natural collagen production and dermal remodeling. In this study, the author examined the efficacy and safety of nonincisional continuous wave fractional CO laser blepharoplasty in the upper lid. Standard lid measurements including marginal reflex distance, palpebral fissure, and upper lid crease were performed preoperatively and at 6 months by the surgeon. All patients underwent full facial MIXTO continuous wave CO laser treatment (MIXTO Slim Evolution 2; MIXTOLasering USA, San Ramon, CA), including resurfacing on the upper eyelid from lashes to brow. We evaluated results at 6 months after laser treatment and found that on average, after MIXTO continuous wave laser treatment, marginal reflex distance of the upper lid increased from baseline from 0.7 to 2.2 mm, palpebral fissures increased from 5.6 to 7.4 mm, the upper lid crease was unchanged at 5.7 mm as was the upper lid excursion at 14.7 mm compared with those before treatment. Patients reported postoperative erythema, edema, crusting, and oozing that resolved within 14 days. These data demonstrate the safety and efficacy of noninvasive continuous wave fractional CO laser in the treatment of mild and moderate upper eyelid dermatochalasis.
