The hospital I used was over 3 hours away from where I lived. It was okay the first 2 years, then in the 3rd year I had a complication which made the distance more difficult. At that time I switched to seeing a dr closer to home. The initial surgery is the difficult part, so I would want to go with a doctor who has an excellent track record and a facility that is capable of handling emergency situations that can happen during or right after you have the surgery. For follow-ups, usually it's something like 2 weeks after, a month after, and then like 3 months, 6 months and a year out. After that, for me at least, it was anual until my complication (which was a freak thing, so in all likely-hood you're not going to have problems).
