The manufacturing process of ocular prosthesis has evolved throughout history. Initially, they were manufactured with an artistic objective, made out of different materials like wood and gold. Today, they are artificial medical devices which are made out of polymethil metracrilate, known for its physical and chemical characteristics and good bio compatibility, and with the purpose of aesthetic and anatomic and partially functional restoration of the patient that presents a loss of malformation of the ocular globe, due to a congenital or acquired origin (trauma or pathology). Its manufacturing involves several processes, which strive to reach a good communication with the patient, in order to learn of his expectations. The main processes in manufacturing are: 1.Perform a copy of the orbital cavity or an impression; 2.Make a mold out of plaster from this copy or impression; 3.Manufacture a plastic version of this copy or impression - polymethil metracrilate - through the process of polymerization; 4.Paint the sample, in order to copy the eye characteristics (such as iris and blood vessels); 5.Finally, polish the surface with abrasive materials, in order to obtain the shinny and soft appearance of a normal eye.

Keywords : ocular prosthesis; impression; silicone elastimeters; polymethil metacrilate; plaster; polymerization.
