Huh... I had no idea ;~D
Best of luck with that.... hope it does the trick.
I have bone dry eyes. Not a lack of reflex (crying) tears, but a lack of lubricating tears.
They thing that the radial keratotomy that I had is the problem...apparently they are seeing a lot of it with post RK patients. They *think* that the nerve endings that communicate with the brain letting it know that the eye needs lubricating tears are cut off and the message isn't getting through.
