Periocular laser complications.

Laser periocular surgery has achieved an increased popularity, particularly since the widespread use of CO(2) and erbium:yttrium aluminum garnet laser and more recently with the development of nonablative laser technology. The main target of these techniques is to treat photoaging changes to obtain a rejuvenated skin. Despite the relatively safety of these procedures on experienced hands, postoperative complications affecting the periocular region, and the eye itself, may follow laser surgery. More common complications include persistent erythema, hyper- and hypopigmentation, and hypertrophic scarring. Viral, bacterial, or fungal skin infections may also jeopardize the postoperative period after periocular laser treatment. Severe burns, transitory or permanent lower lid ectropion, and even corneal injuries or ocular perforation are among the most severe hazards. The majority of these complications are related to the use of ablative technologies. A thoughtful preoperative evaluation, conscientious patient selection, comprehensive informed consent, adequate training, and a cautious and conservative approach are reinforced to minimize moderate or even severe aesthetic and functional periocular complications. Nonablative laser therapies are notably safer; however, their ability to significantly improve photoaged skin characteristics is still limited.
