Workers Compensation?

I recently sustained an eye injury at work. I've had two surgeries thus far to fix the damage caused by the foreign body. Now the healing process is underway and will take time. If all goes well, I'll be fitted with a hard contact lens to cover the corneal defect caused by the injury. If things don't heal well, I will need corneal transplant. Only time will tell at this point. Worker's compensation is paying my medical bills and giving me a weekly check for loss of wages. My questions have to do with long-term outcomes and expectations.

1. Is there a schedule whereby I can determine how much my state will pay out for loss of wages , work placement, vocational rehabilitation, or even permanent partial disability if my vision is not restored? I would also like to know about how long it will take for my eye to heal after all these interventions?

2. In legal terms, how long before I've reached what's called the "MMI" maximum medical improvement?

Bottom line, I would like to get a better sense of the minimum and maximum of what the work comp will pay in the event my vision is lost forever.

Thank you all and god bless
