AB The aim of this work is to provide experimental data for corneal transparency and scattering to help createa more complete model of corneal transparency. The scattered light in 96 healing hen corneas was measuredfor three wavelengths by a scatterometer constructed in the Optics Laboratory (The University of Valladolid,Spain). With the help of mirrors and beamsplitters, the light from the three lasers is directed toward the cellcontaining the sample to be measured. The measured scattered light varies between six orders of magnitude.Corneal transmissivity, mean cosine of a scattering angle, and angular distribution of scattered light were allcomputed. The total transmitted light remained practically constant over a wide range of light valuestransmitted in a forward direction (direct transmissivity). The value of the mean cosine of the scatteringdirection is very close to the unit (g40:98), even in corneas with high opacities. The behavior of g indicatesthat even damaged corneas evidence extremely small scattering, compared to other biological tissues.The transmission reduction of each cornea is related to an increase in scattered light. In all cases, scatteredlight is concentrated at very small angles. This behavior is acceptable in corneas that are healthy or whichevidence small lesions, but remains in corneas that are severely injured.
