I would not use Iodine in the eyes, it takes care of infections, but may be to harsh on the eyes. A better way is a solution of borax in water; dilute in luke warm water, make sure it is no crystals left, put one drop in the eye 3 times a day. I have used this in the eyes of kids with infection or stinging from chlorine in swimmingpools. It works over night with infections, and in seconds if stinging / burning eyes from chlorine.
Borax is used in most eye washes today (and has been since the times of Hippocrates) It is a sodium (tears are salty) and is very soothing for the eyes.
