Abstract

We evaluated cyanopsia by means of achromatic-point settings at several time points started from the day before intraocular lens (IOL) implantation for cataract removal surgery. We intensively measured the initial drift in color appearance; we started the measurement less than 30   min after eyepatch removal, and the measurement continued for several weeks. The shifts were mainly observed in the direction of color space that selectively varies short-wavelength-sensitive cone (S-cone) responses. The time constant of shifts in color appearance was estimated at the initial stage of cyanopsia by fitting exponential curves. The result of fitting suggests that color appearance is recalibrated during cyanopsia by some neural mechanisms with a time constant of several hours. It also became clear that the migration of the achromatic point becomes slower within approximately 12 h after eyepatch removal.
