Designing manufacturing and the clinic application of the prosthesis for the patients with large ocular defects.
OBJECTIVE
To design and manufacture the prosthesis of external type for patients with ocular large defects.


METHODS
Silicon and polymethyl methacrylate (PMMA) were chosen the chief materials: The main procedures are: taking the impression, color mixture, making primitive form of the prosthesis, modification and fixation.


RESULTS
Fifty patients with large ocular defects took the prosthesis, the cosmetic results are satisfactory. All the patients give satisfactory comments on the 5 main indexes: color 90%, stereo-feeling 100%, peripheral difference 86%, fidelity 98% and fixation 86%.


CONCLUSIONS
To make ocular prosthesis, materials with good quality and complicated technology are needed. The prosthesis made by silicon combined with PMMA show good results. Among the procedures of making prosthesis, color mixture and fixation are the most important.
