dry eye disease
"I used Lacrisert 3 times and on the third and final use I experienced extreme adverse reaction that has caused blurred vision that has never improved. 
The pain and vision loss was so bad I was seen in the emergency room triage. 
The nurse stating "This drug has messed your eyes up "
I was given two injections to counter act the drug and one for pain. 
I now live with one eye that will not open completely ,near constant blurred vision to the point I am unable to do anything for up to 10 hours at times. 
My right eye wanders around independent of the left eye. 
An opaque film almost constantly until I can clear it with preservative free Over the counter eye drops. 
This is an incredibly expensive way, but the only way to gain any relief"
