I understand the CAA are still a bit funny when it comes to laser eye treatment (BA expressly disallow it, at least for the CEP scheme), but opinions are changing as confidence rises in the success of the treatment. In the next year or two I'm sure it will be no problem. I guess no-one can be 100% sure what the long term effects of laser treatment will be - though every indication is that it should be no problem, the aviation industry and regulatory bodies are understandably strict when there's potentially such a lot at stake.
It's definitely worth calling the CAA - you may find they've changed their rules by now.
