Mike Zimmer had an eighth surgery on his eye earlier this year. He cannot yet fly in for camp as the gas bubble that helped position his retina for reattachment has not dissipated yet. If camp started next week, he would be driving from Kentucky to Minnesota.
Eye surgery in general is weird, as surgeons will use tools diverse as buckles/belts, lasers, gas bubbles and gravity to help heal the eye. One thing you should never do is look at You Tube videos of eye surgery. You will never go to the Ophthalmologist again.
