It is good to hear that your fathers optic nerve has not been damaged by the short spike in his eye pressure.
When you have scratches on your cornea, or a corneal abrasion
from using eye drops your vision will be fairly poor. Think of as trying to look through the frosted glass windows in a bathroom....
Once the scratches heal --it could take as little as a day or as much as a few days -- then the vision should get much better. If things don't improve by Monday your dad's surgeon may want to try putting a "bandage contact lens
" in his eye. This is a very thin, extended, disposable, large, soft lens
used to protect the corneal surface while it heals.
The drops he is on right now sound goo d to me and it seems that your Dad is in good hands with this ophthalmologist
