Outcome Measures

Primary Outcomes (3)

  • corneal endothelium cell count

    normal range of 1500 to 3500 cells/mm2 (age, 40-90)

    baseline

  • corneal endothelial cell size

    their dimension being roughly 50-70 μm long, 10-30 μm wide and 0.1-10 μm thick

    baseline

  • corneal endothelial cell shape

    a single layer of cells organized in a characteristic honeycomb pattern

    baseline
