Paper Abstract

A prototype was built to provide means for clinical studies of alterations on the cornea UV natural protection from current procedures, such as the refractive surgery and corneal crosslinking. The prototype consists of an optical dual beam UVA/UVB system, for measuring the transmittance of the cornea at the 300nm - 400nm range. The system performs 500 measurements/s (±0.25% precision for the transmittance). It has been correlated to spectrophotometer (0.985) for donated human corneas. Preliminary studies on human corneas demonstrate that as the stromal layer is reduced, there is significant loss of the cornea natural UV protection.
