Abstract:
A method for determining optical properties of a corneal region. The method includes the steps of obtaining a combined tear film aqueous layer plus lipid layer thickness; obtaining a tear film lipid layer thickness; subtracting the tear film lipid layer thickness from the combined tear film aqueous layer plus lipid layer thickness to obtain a tear film aqueous layer thickness; and determining a corneal layer refractive index based on the tear film lipid layer thickness and the tear film aqueous layer thickness.
