RESUMO
The introduction of a new generation of carbon dioxide (CO2) lasers has permitted the development of new approaches toward certain oculoplastic disorders and procedures. The high absorption of this infrared laser by tissue water assists oculoplastic surgeons in performing incisional and excisional procedures precisely and with relatively good hemostasis. The development of new scanned continuous-wave or pulsed delivery systems has facilitated controlled tissue ablation with decreased collateral thermal injury during cutaneous resurfacing procedures. The unique characteristics of the CO2 laser mandate special attention to protection of the patient and surgical team, and careful preparation and training will help the prospective laser surgeon to successfully address the learning curve associated with this new technology. Although long-term follow-up is limited, results reported to date suggest that the CO2 laser represents an important addition to the armamentarium of the oculoplastic surgeon.
