Driving with blue toric IOLs
Early studies have suggested a benefit of nontoric blue light-filtering intraocular lenses (IOLs) when driving in glare conditions. Researchers investigated whether this also was the case for toric blue light-filtering IOLs. Using a driving simulator, researchers studied 18 patients with a toric ‘blue blocker' and 15 patients with a non-toric ‘blue blocker' IOL. The safety margin was defined as the time to collision less the time taken to turn at an intersection with oncoming traffic. In the presence of glare, patients with toric IOLs had significantly greater safety margins than patients with control IOLs, and significantly lower glare susceptibility
