REIS, Ricardo Cesar dos  and  DIAS, Reinaldo Brito e. Use of digital iris in ocular prosthetic rehabilitation. RFO UPF [online]. 2013, vol.18, n.1, pp. 94-100. ISSN 1413-4012.

Introduction: one of the essential factors in satisfactory final result of ocular prosthetic rehabilitation treatment is a faithful reproduction of the iris of the eye remaining in prosthetic iris. It concealment loss for affected patients. Objective: this paper presents a new technique to manufacture prosthetic iris, using the remaining iris scanned image, obtained by photographic image printed on adhesive. Methods: depending on the photo degradation that compromises the longevity of artificial eyes, decided to evaluate the stability of colors, comparing both techniques, through accelerated aging test. For the tests were prepared specimens simulating prosthetic iris, divided into two groups: adhesive sticker and, in green, blue, brown and black. The variation of the degree of degradation was evaluated by colorimetric reading before and after and three weekly intervals during aging with artificial ultraviolet radiation. Statistical analysis suggests that when the colors were evaluated according to the period of artificial aging test, only in blue color in the adhesive group difference was statistically significant. Results: when evaluated as a function of group and trial period, the statistical tests indicate no difference between the colors of adhesive. Conclusion: none of the colors between the groups showed color degradation above the clinically acceptable level.
