Ratchathorn Panchaprateep: The Efficacy of 3 Different Modes of Combined Er:YAG and Nd:YAG for Lower Eyelid Rejuvenation
Owing to modern medical advances, many modalities have been implemented for the treatment of eye bags and lower eyelid rejuvenation. In this study, a novel non-ablative Erbium:YAG laser, renowned for its non-invasive, efficacious laxity treatment via collagen remodeling and neo-collagenesis, is applied in combination with Nd:YAG laser to revitalize lower eyelid glamor.
To study the efficacy of 3 different modes of Er:YAG (2,940-nm) laser combined with Nd:YAG (1,064-nm) laser for lower eyelid rejuvenation.
A total of 24 participants with a mild to moderate degree of lower eyelid bags were recruited in this study. All patients were treated with a four-step laser procedure: Er:YAG SmoothLiftin® (trans-conjunctival approach), Er:YAG SmoothLiftin® (upper and lower lid), Nd:YAG PIANO® (lower lid), and Er:YAG SupErficial™ (upper and lower lid) every four weeks for four sessions. After the physical examination, five views of the periorbital area were captured by digital camera from all participants for uniqueness score grading. The 3D pictures were also recorded by an AnteraÔ camera system for assessment of eyebag improvement. The clinical outcomes were evaluated before, 4 and 12 weeks after the end of laser treatment by means of cutometer and colorimeter (melanin and erythema indices).
Results: 19 participants completed the treatment protocol. The evaluation of lower eyelid bags achieved 33.68% improvement by week 4 after the final laser treatment and even greater 51.05% by week 12. No serious complications were detected.
The combination of 3 different modes of Er:YAG laser and PIANO mode Nd:YAG has yielded promising lower eyelid rejuvenation outcomes with minimal downtime.
