I have an idea what you are going through, John. Other members of my family (father, sister, niece) - totalled up - have had 9 corneal eye grafts. Injections in the eye, drops every hour, patches, pads, can't see to clean the house, etc, and my sister has not driven a car for seven years. Ulceration would be ongoing pain and as you say, eyelid sticking. Grafts rejecting or getting infected, grafts becoming detached and moving within the eye; like this. Over 30 years, we are getting to be experts at looking at very red eyes with ugly white blobs in the middle and making prognostications. White eyes, too.
Well, I am pleased you can open your eye and see some glare.
Like the journey of my family members, it is frustration and stumbling for some time.
I am pleased you are not blind.
We are all pleased about that.
Take your time, and take your patience.
You have every day of your life for your eyes to get better.
So take time.
Chris
