Paper Abstract

A technique has been devised for the measurement of surface refractive index of the cornea in human eyes. It has been shown to be effective in laboratory studies of refractive index in optical components of the eye. A modified approach is proposed, in which a much more accurate measurement may be achieved, with the added advantage of reduced patient discomfort. This is achieved by a non-contact method, and frequency-domain analysis of the optical signals used in the characterisation, which are optimised for best signal to noise ratio.
