    The group index of the cornea, rather than the phase refractive index, is required for thickness calculations with optical coherence tomography. Recent advances with high-speed optical coherence tomography at 1.3 μm make index measurement at this wavelength of great interest. Group indices of three human corneas from an eye bank were measured in vitro with optical coherence domain reflectometry. Measurements were made in a calibrated cuvette filled with a preservation medium to maintain proper corneal hydration. Group indices were calculated from the optical path lengths measured. The corneal group index was 1.389 ± 0.004 (average ± standard deviation). The average group index of a balanced salt solution, an approximation to aqueous humor, was 1.343 ± 0.001
