dc.description.abstract© 2023 Taylor & Francis Group, LLC.Purpose: This study evaluated the luminous behavior applied to materials used in intraocular surgeries. Methods: Discs of the different products were delivered in 19.00 mm × 3.00 mm. Each sample was fixed on support keeping it perpendicular to the spectrophotometer beam. Later, their analyses were carried out in the air/PMMA ratio. The graphs of individual profiles of the measurements along the length were constructed according to each of the filters from the spectrophotometric analysis. In addition, descriptive statistics of transmittance and absorbance for each wavelength presented were correlated for each filter. Results: It is possible to observe that the minimum absorption measure was found in the Red Filter, especially in the blue and green light spectrum. Conclusion: Using filters in PMMA materials appears to improve visual quality in corneal implants, especially the red filter, due to greater absorbance of light leading to fewer light scattering phenomena through corneal rings. However, further studies comparing the effects of different filters on Intracorneal rings should be carried out to elucidate this field of study.
