Where did you hear that Columbus was a pretty good program? I don't think that is the general consensus. They are a 3 spot program, one resident per year. When I interviewed there, I was underwhelmed. Things may have improved since then, but when I visited, Doctors Hospital was a defunct hospital and was vacant except for the ophtho clinic. It was like being in a ghost town. The clinic equipment was old. They covered the other Doctors Hospital branch across town (for ER and consults) and they operate there as well. They didn't seem very busy to me, and in my opinion you learn by being busy. I was unimpressed by their didactic offerings as well. One thing I was impressed with was that the residents and attendings seemed very nice. The other good thing was that if you were interested in pathology, you could head down to cincinnati to spend time with a path guy there. Aside from that I would guess that one could make the most of what they had at the program and emerge a competent ophtho.
If you have a choice, you would be better off elsewhere. If you want to invest all your time there, it probably would end up to your benefit as they always take the "ophtho" intern from their hospital, and apparently they always take this intern from among the med students that rotate there. So you could potentially end up interning there and then get their ophtho spot.
Good luck.
