Laboratory fabrication procedures for the orbital prosthesis showing a molding process (a, b) using a modeling oil-clay (NSP-soft®; Chavant, Inc., New Jersey, USA) on the major facial cast; preparation of a block mold using celadon clay (c) to create a mirrored outer appearance of the orbital skin area; pouring the plaster to make the major mold after Vaseline application to the gypsum area excluding the modeling clay (d); inner surface of the major mold after solidification (e); eyeball attachment after fabrication; the magnet plastic clay (Eyaco®, Goyang, Gyeonggi-do, Korea) mold adaptation on the magnet section in the master cast model (f); adding the liquid silicone color component (Ecoflex^TM 00-10®; Smooth-On, Inc., Pennsylvania, USA) to the main silicone elastomers (Smooth-Cast®; Smooth-On, Inc., Pennsylvania, USA) to finalize the shade of the silicone base (g); pouring the liquid silicone into the main master cast through a small hole in the major mold (h); the initial and raw appearance of the silicone orbital prosthesis on the major facial cast (i) after solidification of the silicone (at least 6 h); trimming and implanting artificial hair in the eyebrow and eyelash areas (j); the outer appearance of the silicone orbital prosthesis (k); and the inner surface that contains the posterior part of the eyeball and the individual magnet with firm cementation (l)
