Light transmission of the cornea in whole human eyes.
The transmission of the cornea for light in the wavelength range 450-1000 nm was measured in steps of 50 nm by means of a photodiode implanted into the anterior chamber of whole human donor eyes. In the range from 450 nm up to 600 nm the percentage transmission was found to increase with wavelength from 80% up to 94%. In the range from 60 nm up to 1000 nm the percentage transmission was between 95% and 98%. The corneal transmission for donors younger than 45 yr (n = 3, 22-43 yr) did not differ significantly from that of donors older than 45 yr (n = 5, 67-87 yr) at any wavelength.
