Does eye surgery really worK?

Since I can't see the nouns this is just a guess, but it sounds close to you are describing pin point hemorrhages. Or in other words broken blood vessels. They enjoy a fancy medical name, petechia, but they are safe. The medical dictionary describes petechiae as pinpoint,perfectly round, non raise, purplish-red spots. Hope this helps. Of course if they get hold of worse instead of better checking with your Dr is other something to consider.

Not to verbs. Should clear up in a afternoon or two.
