I have been diagnosed with recurrent corneal erosion. My eyes are dry all the time. One eye doctor suggests putting small plugs in the ducts that drain tears from my eyes, which should make the tears stay in my eye longer and make my eyes moister. I use artificial tears all day long and an ointment at night. Will the plugs help prevent further eye damage? Also, I have a dry mouth and wonder if I have Sjφgrens syndrome. If I have it, would the plugs still help?
