The GB News presenter has been battling chronic pain for 18 months and last week had a procedure to relieve pressure on his sciatic nerves.
The star, 62, is recovering at home but appeared on GB News via video to update his co-star Isabel Webster and viewers.
Holmes has previously said he isn’t sure when he will back, but he made it clear that he would be returning.
“I have to say, I'm by no means finished,” he told Webster. “I’ve got an appetite for my work, I want to do things and I love working with you in the morning.”
Holmes — who is married to Loose Women star Ruth Langsford — said doctors had told him four times to let his back heal itself but that it wasn’t getting better so he found a surgeon who felt he could try.
“I just got to the stage where I thought, I want my life back, I want my life back,” he said.
The presenter said it was “early days” and that it would probably be about three weeks before they would know if it has been a success or not.
Webster urged Holmes to take his time when it came to his recovery.
She said: “You're a fantastic broadcaster, the famous Irish broadcaster. But you're not a patient man.
"And when I called you this week to say, how are you doing? He said, ‘Well, I'm not cured.’
"I think he thought you're going to wake up from the operating table and be dancing on Strictly Come Dancing!”
Webster said the TV star needed “to be patient” and told him he’d have to “put in the time”.
Holmes replied: “Yes, I suppose so and what I've got to realise that anyone who's been through an operation like this is, it's the inflammation in your nerves and your nerves are agitated and there's inflammation in your body so the pain stays."
He went on: “The surgeon hopefully will have cured the cause of the pain, at least in one leg.
“I think there may be another operation to have.”
