Abstract
Corneal thickness measurements find applications in areas such as diagnosis and management of corneal disorders, corneal surgery, etc.
In this work we present a technique for the measurement of corneal thickness using a CCD camera mounted on a slit-lamp biomicroscope and common image processing software.
Thickness measurements were performed on three RGP contact lenses of known thickness with an average error of 5 µm, SD of 8 µm. Measurements of a living cornea yielded a thickness of 505 µm and a SD of 5 µm for 10 consecutive measurements; this is a very acceptable value.
