Another ophthalmologic application of polymeric biomaterials is the development of ocular prosthesis and biologically inspired compound eyes [197,198]. Such prostheses, commonly fabricated from porous polyethylene, are designed to serve as nonfunctional artificial substitutes for enucleated eyeballs [199].

The microelectrode array is implanted 10-20 ttm from the retinal surface in a viscous fluid, the vitreous humor [5]. The vitreous is a viscoelastic, gel-like substance that fills the ocular cavity [6]. The experimental setup for characterization of the retinal prosthesis components requires a medium that has the same chemical formulation as the vitreous. Since the early 1900s, different materials have been used as vitreous replacements. These substitutes serve two main purposes. First, they are used to replace a dysfunctional vitreous humor in cases where clouding or physical collapse and liquefaction of the vitreous have occurred. The second is temporary or permanent application during retinal surgery. Since arrays are intended... 

Distribution of 35 facial prostheses were reported by Leonard et al. [19] of these, 12 were congenital, and consequently 8 were traumatic, 8 were resected neoplasms and 7 were infectious defect prostheses. Karakoca et al. [20] reported the 60 facial prostheses as 32 auricular, 25 orbital and 13 nasal. Also, Hatamleh et al. [21] studied the types of facial prostheses that were constructed by maxillofacial prosthodontists and technologists as an alternative treatment when mctxiUofacial defects cannot be fulfilled surgically. In that study, 1193 prostheses were recorded and were followed. Of these, 42% of them were ocular, 31% were auricular, 13% were orbital, 12% were nasal and 1% was composite, that is, more than one facial prosthesis.
