Ocular Prosthesis Fabrication in Group I (Conventional Method)
SCLERA
In the case of Group I, a conventional custom-made ocular prosthesis was created following the original technique described by Cain [For the iris disk (Factor II Inc., Lakeside. AZ, USA) was utilized and painted using oil pigments (Gouache oil, Northampton, USA) or earth pigments dissolved in a solvent such as monopoly to achieve the same color as the iris of patient’s healthy eye. A 1 mm reduction was made from the scleral surface to create space for a layer of clear acrylic resin. Subsequently, the sclera was painted and characterized to mimic the appearance of the sclera of the contralateral eye. The iris disk was positioned precisely in the previously determined iris position, and a layer of clear, heat-cured acrylic resin was applied to encapsulate the assembly. The ocular prosthesis was then meticulously finished, polished and subsequently delivered to the patient (Fig.
