Diurnal Variation of Ocular Hysteresis, Corneal Thickness, and Intraocular Pressure

ABSTRACTPurpose.To investigate, in healthy Asian subjects, the diurnal changes of the corneal biomechanical properties of corneal hysteresis (CH) and its relation to fluctuations of intraocular pressure (IOP) and central corneal thickness (CCT) after sleeping.Methods.Forty eyes of 20 healthy Asian v
