All retired dentist John Seberg wanted was some relief from the nagging back pain that had reduced his normal gait to an awkward shuffle.
Instead, the surgery on his spinal canal that was performed at the Mayo Clinic in Rochester, Minn., on Oct. 22, 2005, left him far worse off than he could ever have envisioned. Following the 13-hour surgery, Seberg awoke from the procedure in complete darkness. Assuming the night hour responsible for the darkness, he thought little of it.
But as time passed, he came to realize the darkness that enveloped him was his cruel fate alone. He was blind. Against all odds, he became only the seventh patient in some 6,000 procedures at the hospital to lose his sight because of the surgery.
