Purpose: To evaluate and compare, color stability of prefabricated and custom made ocular prosthesis. Method: 20 samples of prefabricated ocular prosthesis and 20 samples of custom made ocular prosthesis were taken in 2 groups. Both were checked before the immersion and after immersion in neutral soap solution after 6 weeks. To assess the color change, spectrophotometry test was performed; and the results were statistically analysed by Mann-Whitney U test and Wilcoxon Signed Rank Test. Result: Among prefabricated and custom made ocular prosthesis as painted with oil paint; prefabricated ocular prosthesis showed more color stability, after immersion in neutral soap solution for 6 weeks. Conclusion: Prefabricated ocular prosthesis, is more color stable.
