Peter B. Delahunt studied long-term changes in color appearance after cataract surgery. Repeated achromatic adjustments track adaptation to an altered optical input over time. Different recovery rates for appearance and discrimination help separate distinct measured outcomes; surgery changes the incoming light as well as the conditions for subsequent neural adaptation.
