I have just had my 3rd set of punctal plugs in the two main tear ducts of both eyes. It is bliss! Don't feel that constant need to close my eyes all the time, especially evenings, so not good for the social life! I need far fewer eye drops too. Only thing is, they don't last for ever. In fact, I've only managed to keep them in for about 2 months on the previous occasions. But at the moment it's just lovely! Highly recommended.
