Even back in the time of Pulaski there had been ocular implant variables that Geordi could've opted for. He refused on the grounds that the technology hadn't advanced enough to allow him comparable vision iirc.
Yup, in "Loud As a Whisper", Pulaski surprises LaForge by offering him two things Crusher never did: replicated real eyes (which LaForge doesn't want because he thinks this would mean "giving up a lot") and ocular implants with some but not full VISOR functionality (which would mean giving up "20 %" or thereabouts, and LaForge has doubts about that as well).
One has to kind of assume that after his visor had been used twice as a weapon against his ship & crew, he began considering for one reason or another, that implants would be much less vulnerable to foul play.
Why would they be any less vulnerable? They're machines, they can be hacked into.
Then again, all the heroes can be hacked into, and have been. Their biological components are likely to be less resilient to hacking than their machine bits, really, having never been engineered to block a hacking. I doubt LaForge would have any rational reason to think that he's a special vulnerability, with or without a fancy eye prosthetic.
Plus, by the time of FC, the tech might have advanced significantly. In my head canon, his friendship with Data might have even been the very thing to advance it, as Soong android eyes (like the VISOR) are essentially Federation tech, but that do allow for humanlike vision (as evidenced in some of the POV stuff we see in Data's dreams)
We never hear Data would be particularly high tech, though. I mean, he spent the first few decades of his life not being considered that. The only thing worth a mention is his positronic brain, and that one doesn't really become evident until the events of "Datalore" where Data for the very first time gets associated with Noonien "Positronics" Soong.
But yeah, LaForge might have chosen the new techno-eyes because they no longer meant "giving up 20%" and might in fact have been better than the old VISOR in some respects. He never sounded like a guy who'd be willing to downgrade - see the one where he has to face giving up high warp, say.
As for Data's vision, he never performs any special feats with it. Indeed, there's a direct comparison in "Heart of Glory" with the two looking at the same targets, and LaForge seeing things such as android glow and metal fatigue while Data merely relies on his tricorder to detect life signs. Sure, Data is likely to be able to focus better than humans, in the mental sense - much like how he can discern signal in auditory noise. But he's not a pair of field binoculars on any away mission (again, LaForge is, in "Hide and Q"!).

At the time, I rolled with it, but I roll with Space:1999 as well and that one takes the cake for its contrived premise requiring massive suspense of disbelief to enjoy. So it can be worse than using copious syllables' worth of treknobabble. 
Possibly because "Genesis" is still theory no matter how stretched, whereas the moon traversing the galaxy so fast due to a nuke boom-boom despite infraluminal velocity is just completely daffy. Episodes in isolation, like "War Games", do manage to make up for it. Just take some nice drugs before sitting through most of season 2 and one can survive it as well...
