Materials and methods: One-hundred-and-twenty specimens were fabricated and distributed in 12 groups. The analysis was carried out by means of digital roughness meter. Results: Data were analyzed statistically by ANOVA and Tukey test at 1% significance. The results showed that there was no statistically significant difference after the weathering period. Both the Vipi Cril acrylic resin with 3.5 mm in thickness and ocular button with 1 mm in thickness presented the lowest roughness values (0.12. Ra). Conclusion: The roughness of the acrylic resins and the ocular button was not affect by the weathering of 1008 h. However, the thickness of the specimens proved to have a major influence on roughness property. © 2010.124-127engOcular prosthesisRoughnessThicknessWeatheringacrylic acid resinethylene glycol dimethacrylatemethacrylic acidmethacrylic acid methyl estercontrolled studymaterials testingpolymerizationpriority journalprosthesis materialsurface propertythicknessvisual prosthesisAcrylic ResinsBiocompatible MaterialsContact LensesEquipment DesignEquipment Failure AnalysisHardnessMaterials TestingSurface PropertiesArtigo10.1016/j.clae.2009.12.008Acesso restrito2-s2.0-7795289111297198838148725820000-0002-3800-3050
