The BBC Weather star told Woman magazine that she is starting to lose vision in one of her eyes and needs to get it fixed before it deteriorates any further.
She said: "I've got to have an operation on my eye and even though it's minor, I'm still a little scared. I've got such a droop eyelid. I'm starting to lose part of my sight. And it will only get worse, so I'd better have it sorted."
Carol is currently juggling her BBC Weather commitments with appearing on Strictly, which kicked off its new series last month.
She's been partnered with Pasha Kovalev, who has previously won with Caroline Flack.
