Ketorolac
"My doctor had me on a dosage of Acular LS of one drop per eye per day.  It ELIMINATED my photophobia (sensitivity and pain) which was caused by cornea transplants that I needed to treat my Keratoconus.

Even though my dosage was 1/4 the normal dosage recommendation my doctor took me off the Acular LS since a known effect of the medication at normal dosages is thinning of the cornea.

I have found no other treatment that helps with my photophobia.

This stuff will sting when you use it, but it definitely works.  For the time that I used it, I could participate in outdoor activities, view fireworks, basically tolerate normal activities.  Without it, I'm confined to a dark hole.

So the product is great!  Just wish I could continue using it."
