The ocular complications of periocular laser surgery

Laser periocular surgery has achieved an increased popularity, especially since recent technical developments in the carbon dioxide and erbium:yttrium-aluminum-garnet lasers. Despite the relative safety of these procedures in experienced hands, postoperative complications affecting the periocular region, and the eye itself, may follow laser surgery. Common complications include persistent erythema, hyper- and hypopigmentation, and hypertrophic scarring. Skin infection (viral, bacterial, or fungal) 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. A thorough preoperative evaluation, appropriate training, and a cautious and conservative approach are reinforced to minimize such problems.
