Efficacy of pig-to-rhesus lamellar corneal xenotransplantation.

abstract：Purpose:Aging affects a variety of visual functions. In this study, we aim to quantitatively investigate the temporal characteristics of visual processing in aging. Methods:Twelve younger (24.1 ± 1.6 years) and 12 older observers (58.4 ± 3.6 years) participated in the study. All participants had normal or corrected-to...
