An orbital implant is usually a spherical implant that has a slightly smaller diameter than the human eye. Modern synthetic materials that are well accepted by the body are used during the production.
During enucleation, the eye to be removed is surgically replaced by the implant. The eye muscles are then attached to the implant. It is then covered by conjunctival tissue to minimise the risk of infection. This procedure has become the standard procedure in modern medicine. An orbital implant is a basic requirement for a good fit and the high mobility of an artificial eye.
