The ringside doctor ruled Berridge could not continue with the cut that deep before the start of the eighth round, which under the rules meant the result went to the judges scorecards as the fight had progressed past the fourth round.
Ford was then quickly announced as the technical points winner, although no actual scores were read out, with the Berridge camp leaving the ring immediately afterwards.
"I was winning every round of the fight, I was picking my punches," Ford said.
"Robert Berridge is a real tough competitor, but every one of those fights, he gets cut, so I can't complain.
"Can't take it away from my win...I got the job done."
The event's promotors Ringstar Boxing later announced on their Facebook page that the three judges were scoring the bout 67-66 69-64 and 68-65 in favour of Ford (12-0) by the end of the seventh round.
Berridge, now 29-7-1, has lost two fights in a row for world belts in overseas bouts.
