Enucleation in ophthalmology is the surgical removal of an eyeball. It is usually implemented due to untreatable eye tumours, such as e.g. a retinoblastoma, but also following severe eye injuries.
The fatty and conjunctival tissue are both left in the eye socket. The eye muscles are normally also retained and then attached to an orbital implant. This procedure not only ensures a good fit of the artificial eye, it also results in high mobility of the prosthesis.
