Hello! My name is Jessica, I am a physician assistant, and one of the providers at Aesthetic Skin in Winnetka and Chicago. This is a great question. Yes, the lack of eye shields during your Tixel treatments on the eyelids could potentially pose a risk to your corneas. Tixel is a thermal fractional treatment designed to stimulate collagen production and improve skin texture, and it involves applying controlled heat to the skin. The absence of eye shields means that your eyes were exposed to this heat, which can be harmful. Without appropriate protection, the corneas can be subjected to intense thermal energy, leading to potential issues such as irritation, inflammation, or even damage to the corneal surface. Symptoms like dryness, redness, or discomfort could indicate that the corneal tissues were affected. Prolonged or repeated exposure to such energy might exacerbate these issues and increase the risk of complications. If you are experiencing any discomfort or visual changes, it is crucial to consult with an ophthalmologist promptly. They can perform a thorough examination to assess the condition of your corneas and provide appropriate treatment or recommendations. For future procedures, it is important to ensure that adequate protective measures, such as eye shields, are used to prevent potential damage and safeguard your eye health. I hope this helps and best of luck!
