Abstract

Moiré contour fringes were generated on the human corneal surface, following the instillation of a fluorescein solution onto the eye. The depth interval between the two adjacent moiré fringes was made to be 0.148 mm at all fringe orders by using a telecentric optical system. The meridional sections of normal and abnormal corneas were quantitatively profiled with an accuracy of about 0.005 mm. It was concluded that this corneal topography was advantageous, especially in determining the configuration of abnormal corneas, such as conical corneas and those that occur just after cataract extraction or corneal transplantation.
