Abstract
The donated cornea transparency is one of the features to be analyzed previously to its indication for the transplant. Hence we have developed a system to evaluate the transmission spectrum of 'In Vitro' corneas in its preservative medium, in the range of 400 - 700 nm, to be implemented in an Eye Bank. The cornea in its preservative medium is illuminated by collimated white light beams which strike a diffraction grid, passes through an optical system and a selecting filter (400 - 800 nm) and then is detected by a linear CCD detector (2048 photodiodes). The data is displayed in a PC monitor via a commercial interface device. A dedicated software has been developed to plot the transmission spectrum profile and provide an objective and standard information about the transparency of the donated cornea.
