Rokohl AC, et al. - Researchers, herein compared the concerns of experienced cryolite glass and (poly)methyl methacrylate (PMMA) prosthetic eye wearers. Compared to PMMA prosthetic eye wearers, many general and specific levels of concerns (loss of balance, phantom sight vision, pain, receiving good advice , fullness of orbit, size, direction of gaze relative to the healthy fellow eye, eyelid contour, comfort of the prosthetic eye, colour relative to the healthy fellow eye, and retention of the prosthetic eye) were significantly lower for the cryolite glass prosthetic eye wearers. They noted that in both the groups, concerns about watering, crusting, discharge, visual perception, appearance, movement of the prosthetic eye, and health of the remaining eye were not significantly different.
