A full visual range IOL with violet light filtering showed good tolerance to induced astigmatism in patients corrected for distance vision, according to a study published in Journal of Refractive Surgery.
Hugo T. F. Borges, MD, and colleagues wrote that previous research has shown that IOLs can enhance contrast sensitivity by filtering high-energy violet light, which reduces scatter as well as dysphotopsias. They wanted to find out how the IOL under study might interact with residual refractive error.
“The increasing demand for high-quality visual outcomes is driven by patients’ elevated
