Meta Description: Ocular prostheses have a long history of successful use, and variations in the techniques and materials used have been introduced through the years. Advantages such as reduced treatment time and increased simplicity make this method a good alternative to conventional tedious methods of fabricating ocular prostheses.
Ocular prostheses are either readymade (stock) or custom made. The use of a stock prosthesis is usually advocated when time is limited and cost is a consideration. However, a large and expensive inventory of readymade prostheses is required if an adequate iris selection is desired. The prosthesis must then be fitted to the socket. The custom built hand painted and individually constructed acrylic resin artificial eye has proved to be the most satisfactory ocular replacement. Custom building however necessitates the services of a skilled artist for duplication of the iris and sclera and is an involved and time consuming process. The need for an artificial eye can sometimes be satisfied by stock prostheses that are available in standard sizes, shapes, and colours. These prostheses can be used for interim or postoperative purposes. No special skills or materials are required for fabrication.
Stock prostheses are relatively inexpensive and can be delivered quickly. The required clinical and laboratory time is not significantly less than the time required to make a custom ocular prosthesis, but the result is rarely equal. Fabrication of a custom ocular prosthesis allows infinite variations during construction. The close adaptation to the tissue bed uses the full potential of the implant to produce movement. Implants here refer to a solid sphere used to restore the loss of volume of eye sockets to enhance the prognosis of the subsequent prosthesis. However the use of these implants may be restricted only to cases that have involved surgical excision of substantial volume of underlying tissue.
