Efficacy and Safety of Ultrapulse Carbon Dioxide Laser Treatment in Eyelid Tumors

-Background: The assessment of the efficacy and safety of Ultrapulse CO₂ laser in treating eyelid lesions is crucial for clinical applications. This study aims to evaluate the effectiveness of super-pulsed CO₂ laser in treating different types of eyelid lesions, particularly marginal and large lesions, to provide comprehensive clinical guidance and decision support. -Main Objectives: A retrospective analysis of the efficacy and safety of Ultrapulse CO₂ laser treatment for various types of eyelid lesions, including xanthelasma, pigmented nevi, keratoses, and so on. -Study Design: This study will include 1000 patients diagnosed with eyelid lesions, including xanthelasma, pigmented nevi, keratoses, and so on. All patients undergoing Ultrapulse CO₂ laser treatment. The evaluation will focus on the efficacy and safety of Ultrapulse CO₂ laser treatment for different types of eyelid lesions. -Study Population and Anticipated Enrollment: Patients with eyelid lesions (n=1000) -Inclusion Criteria: Clinically diagnosed with eyelid lesions, including xanthelasma, pigmented nevi, keratoses, and so on. No history of photosensitivity, bleeding, or coagulation disorders Willing to attend follow-up appointments as scheduled -Exclusion Criteria: Presence of infection in the target area Allergy to lidocaine Keloid-prone or poor skin repair ability Pregnant or lactating Recent history of severe infectious diseases, active skin diseases, or major diseases affecting the cardiovascular, liver, kidney, endocrine, and hematopoietic systems History of malignant tumors or immune system disorders
