Continued generic tilex fresh shower-related eye trouble (?)

On June 11th, I posted a message titled 'target "tilex" fresh shower
clone in eye?'. I received a helpful response, but I now have more
information about the situation that I was hoping I could get comments on.

The 5 milky-white spots on my right cornea are still there (likely, but
not necessary, due to exposure to a target brand generic form of "Tilex
Fresh Shower"). My opthalmologist believes the spots may be looking
better than they were on my first visit.

My opthalmologist borrowed a cornea specialist during my most recent
visit, and the cornea specialist believes that I have some damaged
epithelial tissue on my cornea, and some new undamaged epithelial tissue
has formed over the damaged tissue, preventing the damaged tissue from
going away.

The two of them decided that if I want to treat the situation (I can still
see reasonably well with appropriate, but very different from before,
correction), then I should either:

1) Try a "bandage contact", which in this case means a very low-correction
disposable, to cut costs

and/or

2) See a cornea specialist about getting the damaged epithelial tissue
scraped away with a scalpel.

I'm currently trying to "bandage contact" route.

Do these approaches make sense to sci.med.vision net.wisdom? What is
the purpose behind the "bandage contact" method?

Thanks!
