There are two types of artificial eyes:
Prosthesis made from impression This technique involves orbital impression printing, allowing a perfect adaptation of the prosthesis to the orbit. An implant is placed in the orbital cavity during prior surgery, enabling natural movement. This method is most effective in conveying that movement.
Scleral – shell prosthesis – Prosthesis are always adapted to eyes without vision, with corneal opacities, phthisis bulbi, or simply smaller size, generally in most cases where the eye has been preserved.
Both types maintain a mobility with a natural appearance, especially the impression-based prosthesis, and provide basic lacrimal distribution for good tolerance.
