If you are talking about someone who is both near-sighted (myopic) and suffers from age-related far-sightedness (presbyopia), I presume he means the KAMRA implant.

I am not surprised it is "banned" for pilots. This implant is a ring implanted in the cornea that narrows the pupil opening. The "pinhole effect" makes the image projected to the retina sharper (a theoretical pupil with a diameter of almost zero would project a sharp image without a lens!), but it makes the eye unsuitable for anything but good light conditions, and hence is normally only implaned in one eye.

If the choice is this or a pair of reading spectacles, I go for the latter.
