Theoretical light scattering calculations, when applied to models base
d on structures seen in electron micrographs of corneal stroma, requir
e knowledge of the constituent fibril positions and radii. Obtaining t
his information manually is a difficult and time-consuming task. In or
der to facilitate this problem, we present a simple and flexible compu
ter algorithm that allows the process to be automated using a Macintos
h computer. The accuracy of the results is checked by comparing light
scattering calculations using fibril positions and radii found manuall
y with those found by the computer. The results show that the computer
algorithm is a viable and accurate means of obtaining the needed data
.
