For what it is worth, since I am in FAA land--
After a monofocal implant my eye has an uncorrected distant vision of 20/15. Near vision matches the other eye, and meets standards with simple "readers" off the rack.
You need a doctor who will take the time to match your eye with the best/correct implant. I am told that this is the step that many do not put a lot of effort into, which in turn leads to less than ideal outcomes.
Also avoid the multifocal implants, since your odds of getting 20/20 are lower, even with correction.
Certification was not an issue. Rest assured that you are not the first pilot with this problem.
