Why Eye Prostheses Should Be Replaced Regularly—From Infancy to Old Age - Beryl Carvalho - Eyes Alive

An ocular prosthesis is a custom-made medical device that must continuously adapt to a person’s physical changes. From early childhood through old age, both the anatomical conditions and the requirements for comfort, function, and aesthetics change. Regular checkups and timely replacement are therefore essential to ensure long-term care and prevent discomfort.

Why Eye Prostheses Should Be Replaced Regularly—From Infancy to Old Age

An ocular prosthesis accompanies many patients for years or even a lifetime. Nevertheless, it is not a device that is fitted once and then remains unchanged forever. The most important reason for this is simple: People change, and with them, the eye socket changes as well. In addition, a glass ocular prosthesis is subject to natural wear and tear in everyday life. This is precisely why regular checkups and timely replacement are not minor details, but an essential part of good ocular prosthetic care.

Why an ocular prosthesis must be regularly adjusted or replaced

An ocular prosthesis must not only fit well initially but also remain a good fit for the patient’s anatomical conditions over the long term. Changes in the eye socket, the eyelids, and the surrounding tissue can cause a prosthesis that originally fit well to lose comfort and function over time. Added to this is material wear: Glass prostheses, in particular, are constantly subjected to stress from tears, deposits, and daily wear and tear. Regular checkups and timely replacement are therefore crucial for comfort, aesthetics, and tolerability.

Ocular Prostheses for Infants and Toddlers: Supporting Orbital Growth

During early childhood, growth is the primary focus. If a child is born with anophthalmos or microphthalmos, or requires an ocular prosthesis at an early age, the prosthesis must actively support the development of the eye socket, eyelids, and face. During this phase, the face grows dynamically, and the prosthesis serves not only to enhance appearance but also as a space maintainer and shaper. It helps keep the eye socket open and supports development that is as symmetrical as possible. For this reason, babies and young children require more frequent checkups and, often, shorter replacement intervals than later in life. Specialized information on this age group can be found under “Ocular Prosthetics for Babies and Toddlers.”
