An ocularist may select the stock eye that is most closely matched to patient's iris color.
In addition to creating the prosthetic eye, an ocularist shows the patient how to care for and handle the prosthesis.
Therefore, this field is practiced in many places by maxillofacial prosthodontists, dentists who have undergone 3–4 years of specialty residency training.
There are also people who use the title of ocularist who have had no formal training in the fitting, manufacture, and delivery of ocular prosthetics.
The American Society of Ocularists teaches the fitting, fabrication, insertion, and maintenance of artificial eyes.
