Chellappa et al1 have studied sleep and sleep-associated physiology and the association of cataract surgery with implant lenses that produce not only better imaging, but also better transmission of the visible spectrum. The authors recorded paraclinical photoentrainment parameters, electroencephalography during sleep, and sensorimotor reaction times in patients with newly bilateral pseudophakia and implant lenses that block only ultraviolet (UV) or UV plus blue light and compared them with healthy controls. The study included 13 individuals with pseudophakia and 16 controls, all with a conventional sleep/wakefulness pattern and good sleep quality according to the Pittsburg sleep quality index score. The study was headed by researchers dedicated to the study of diurnal rhythms and their influence on human sleep and psyche.
