Normal Size Blind Exotropic Eye
When there is deviation of the effected eye plus noticeable
difference in the scleral whiteness and its vascular pattern,
it becomes necessary to duplicate the thin Phase I clear
acrylic trial shell in white acrylic. This Phase II
procedure is to scribe a pupil center and iris diameter that
aligns with the fellow eye, then trim down the anterior surface
and proceed to duplicate the overall surface of the normal
eye. All white acrylic removed prior to the painting
is then replaced with a polymerized clear acrylic overlay.
This trauma induced exotropic left eye is wearing the acrylic
clear trial shell and was well tolerated and could be worn
for all her waking hours.
A white acrylic duplicate of the trial shell is then marked
for pupil center and a scribed circumference for the iris
painting. The shell was thinned down to one fifth of
a millimeter in preparation for the surface painting.
The scleral prosthesis is completed with clear acrylic over
the painted surface which gives the iris an appearance of
