A protective device intended to be placed on the cornea of a patient to protect the eyes from physical damage and/or exposure to primary and scattered radiation during a medical procedure [e.g., periorbital surgery, x-ray/CT scan, dermatological laser treatment]. It is typically in the form of a dome and is made of non-biodegradable, durable materials (e.g., lead, tungsten, glass, plastic) that provide mechanical protection and/or prevent the transmission of harmful radiation to the eyes. This is a single-use device.
