Diffraction haloes resulting from corneal oedema and epithelial cell size.
Corneal oedema was induced by exposing the corneas of nine subjects, covering an age range from 20 to 64 years, to distilled water for approximately 25 min. Measurement of the diameters of the associated diffraction haloes observed around a small 633 nm source allowed the size of the diffracting elements within each cornea to be estimated as about 10 microm, in good agreement with direct measurements by in vivo confocal microscopy of the subject's basal epithelial cells.
