Dnvrfox I had the laser surgery to open up the ducts to drain better. Its fast like 3 mins per eye and very nearly painless.
The doctor explained that it just stimulates the cells to open up the ducts or some such its not a destructive procedure.
Also he said by doing it I could avoid eyedrops. I had it done in January and my pressure is now low normal 13 in one eye and 14 in the other.
