Keratoconjunctivitis Sicca
"Restasis - not the greatest. Seems to cause light sensitivity and filminess to where it can be like trying to see thru very light smoke or fog. I have not been impressed.
Theratears or something else seems to provide better relief.
 I think it would be worth investigating to see if Restasis is less effective on people over 60, or who have had ocular implants.
The actual price of the stuff  seems a real gouge. Fortunately, insurance pays the most of it."
