Yellow-tinted lenses offer same visual function as non-tinted IOLs

Patients receiving yellow-tinted IOLs can be assured their visual acuity will be “virtually the same” as patients without tinted lenses, according to one study.
Ken Hayashi, MD, compared 74 patients who received either short wavelength, blue light blocking, yellow tinted IOLs or traditional non-tinted IOLs in both eyes. The researchers measured eyes for contrast visual acuity with and without glare source under photopic and mesopic conditions at 2 weeks and 3 months postop.
“No significant differences between the yellow tinted and non-tinted IOL groups were observed in mean visual acuity or in photopic or higher luminance mesopic contrast visual acuity with and without glare source,” Dr. Hayashi said.
He added that the incidence of patients who noticed cyanopsia in the yellow-tinted group was significantly less than those who noticed it in the non-tinted IOL group 2 weeks after surgery. No patients in either group reported cyanopsia at 3 months, according to the study.
The study was published in the British Journal of Ophthalmology.
