Abstract
We welcome the comments regarding our article1 from Drs
Mader and White, who have published several articles on
refractive changes induced by hypoxia in subjects after refractive surgery. We value their additional account of the
mechanism of the corneal changes in Dr Beck Weathers’
eyes during his climb on Mount Everest that led to severe
vision loss. This is an interesting amendment to our manuscript, which focuses primarily on mountaineers with
healthy corneas.
