A patient told me today that her mother noted her eyelashes grew when she used Restasis. I had not heard this complaint so had to look it up.
It turns out there is 1 case report published on this phenomenon and a couple of online blog posts noting Restasis may be associated with longer eyelashes. The blog post below notes the eyelashes that grew were irregular and an annoyance. I could not find any randomized, controlled studies to prove this.
There are a couple of blog posts noting a patient who LOST eyelashes using Restasis. Again, I could not find any randomized, controlled studies to prove this either (Ref 4).
Meibomian gland dysfunction can absolutely cause eyelash drop–out and trichiasis (the growth of abnormal eyelashes), so it is hard to say which of the above patients had this as a cause of eyelash issues.
Cyclosporine A Eye Drop-Induced Elongated Eyelashes: A Case Report
It has seemed to help the dry eye issue, but hasn’t resolved it 100%. But any improvement is welcome. And like Kayjay said, as long as you don’t touch the tip you can use it a couple of times before throwing the little vial out. Be careful though, Restasis doesn’t have any preservatives so if you keep using it after you’ve opened it bacteria might have a chance to grow in it and cause an eye infection.
On a side note, it makes your eyelashes grow! I have not been able to find any legitimate research to back this up, but on me the change is definitely noticeable. A nice fringe benefit to have when you’re dealing with eye crap.
