The UK CAA requirements are here:
UK CAA Eyesight Requirements
Whilst they accept people who have had corrective surgery, their eyesight must meet the limits which someone wearing corrective glasses would have met before surgery (+/- 5 dioptres). In other words, if wearing glasses won't raise you to within the limits then the corrective surgery won't either.
In any event, give the CAA Medical Branch or NATS a call to discuss it as they will be able to give you chapter and verse. The ATCO standards are broadly similar but there may be a slight difference or two which might give you a chance.
