An orbital prosthesis serves as a removable artificial device designed to replace the eye, eyelids, and the surrounding bone and skin in cases of ocular loss or defect. This prosthetic device is crucial for both functional and aesthetic purposes. Although the orbital prosthesis does not facilitate movement of the eyelids or the eye itself, it plays a significant role in protecting the eye socket and the underlying tissues from potential harm caused by debris and bacteria. Additionally, it enhances the cosmetic appearance of the individual, providing a more natural look. The process of creating an orbital prosthesis begins with making an impression of the orbital defect, which is a critical step in ensuring a proper fit. From this impression, a mold is crafted, which serves as the foundation for the prosthesis. The orbital prosthesis is typically constructed from medical-grade silicone that is meticulously color matched to the patient's skin tone, ensuring a seamless integration with their appearance. The eye component of the prosthesis is fabricated separately from acrylic material, which is also color matched to the patient’s natural eye color. Once both components are prepared, they are connected to form the complete orbital prosthesis. The final device is then secured in place using specialized adhesives. In cases where a retained orbital prosthesis has already been constructed, its placement may occur during a separately reportable surgical procedure, highlighting the complexity and individualized nature of this restorative process.
