keratoconjunctivitis sicca
"I have been using restasis single use vials for years and they have definitely helped my post lasik dry eyes--eye doc confirms corneas healthier, no dry patches.  I was using the single use vials, using each one twice as everyone does, with no problems.  I decided I'd try the multidose vials.  I'd make the same comments as others--they are hard to dispense, dispense more than you need, and will not last a month, let alone 45 days, which makes them more than twice as expensive as the vials.  We will see if Allergan keeps its promise to keep making the vials, as they will obviously increase profits with the multi use bottles."
