3.1.3 Fabrication of resin sclera
The acrylic resin was bench polymerized for 5 minutes and then, placed in boiling water at 210 degrees F for 30
minutes (Artopoulou et al., 2006). After the completion of curing, the acrylic eyeball was finished and polished
(Figure 6).
3.1.4 Photograph of adjacent natural eye
A high quality digital photograph of the patient’s contra-lateral natural eye was obtained using a DSLR camera
(Nikon D3200 with the 18-55 mm lens) (Figure 7). The image obtained was edited and three sizes were cropped
viz.11 mm,12 mm and 13mm in the image editing software; Adobe Photoshop CS5. (Adobe Systems Inc.).
Different combinations of brightness and contrast were used to produce a variety of images so as to match the
patient’s eye perfectly at the time of try-in (Figure 8).
3.1.5 Trial of processed resin sclera
When the prosthesis was placed in the socket, the orbicular muscle was allowed to relax for at least 10 minutes to
permit critical evaluation (Kumar et al., 2014). The prosthesis was checked to fulfill all the criteria as done at the
time of wax trial. (Figure 9) 1mm of acrylic was then removed from the iris portion of the eyeball on the frontal
surface in the palpebral fissure area.

3.1.6 Customization of the iris and characterization of sclera
The modified images were printed on a photo paper. After a satisfactory try-in of the scleral blank, the images
printed on the paper sticker were placed one by one in the area which was reduced by 1 mm and matched against
the natural eye of the patient. The image that simulated the appearance perfectly, was selected and pasted on the
scleral blank with the help of cynoacrylate adhesive (Fevikwik, Pidilite Industries Ltd. Mumbai, India) to confirm
the position and appearance in the patient.
