Factors affecting dimensions of the 3D ocular prosthesis in patients rehabilitated at Mahidol University
Main Article Content
Abstract
Objective: This study aimed to evaluate three factors affecting dimensions of the ‘3D ocular prosthesis’ in patients rehabilitated at Mahidol University.
Materials and Methods: A cross-sectional study was conducted on non-irradiated and healthy anophthalmic patients, including 82 subjects aged above 15 years old. All 82 customized ocular prostheses, fabricated following the Mahidol University’s patent, were measured with a digital caliper (Mitutoyo 573 Digimatic Absolute Point Caliper) in horizontal, vertical, and anteroposterior (thickness) dimensions. Three main factors (age, gender, and surgical techniques) were evaluated in relations to the dimensions of an ocular prosthesis. The data were statistically analyzed using an independent t-test and a one-way ANOVA.
Results: An independent t-test showed that a horizontal dimension was significantly greater in males than females (p=0.020), and a thickness dimension was significant difference significantly different in surgical techniques, which enucleation technique showed thicker ocular prosthesis compared with evisceration technique (p=0.024). However, one-way ANOVA showed that all dimensions of an ocular prosthesis were not significant differences significantly different among age groups (p>0.05).
Conclusion: This study presented the first set of data for the 3D ocular prosthesis in patients rehabilitated at Mahidol University. Gender had an effect on horizontal dimension whilst surgical technique had an effect on the thickness of ocular prosthesis.
