The lore goes that after his VISOR was used to facilitate the destruction of the Enterprise D, Geordi was informed that if he was going to keep serving on starships, he was going to have to go to less hack-able accommodation.
Don't know if there was planning to replace it earlier.
I doubt that was ever ordered. Data has proven just as "hackable", in not only
Brothers (understandable given it was Soong) but also by Ira Graves & Lore
Plus, all the other humanoid officers have been "hacked" via possession, 3 of them in
Power Play alone. Data was one of
those too lol. Troi's got another in
Clues. Picard had the mother of all hackings, by the Borg, which threatens virtually everybody, & then everybody BUT Data got hacked in
The Game.
Besides, I'm not so sure the VISOR ever really got hacked. Geordi had his VISOR
inputs used against him in
The Mind's Eye, and I don't think Soren actually hacked the VISOR, so much as he somehow installed a surveillance device in it, that went undetected, because the Klingons aren't seeing Geordi's actual VISOR feed. (that we've seen before) It's just a normal video feed, & it would make sense that Soren just cob-jobbed the easiest thing, to appease them, as he had other more preoccupying goals.
However, after losing his ship, having the Romulans brainwash him, & even Lore was tinkering with it in
Descent, all within a 5-6 year span, I do imagine discussions were had, & Geordi voluntarily decided to look into upgrading. Let's not forget that his later implants DO look like an upgrade too, unlike what the docs had proposed to him, in the early seasons of the show.
It's likely by nearly a decade later, improvements had been made in ocular implant tech... OR! my head canon... In the absence of suitably equivalent implant tech, Geordi, Data, & maybe Beverly worked the problem themselves, in the downtime between ships.
By using the best current ocular implant research, PLUS involving their own even rarer knowledge of
Data's android eye tech, & the fact that both Data's body & Geordi's VISOR had been, in some ways, already compatible with other Starfleet tech, they devised a NEW ocular implant that incorporated ALL of these advantages into one advanced, all-in-one super-implant, which I'd like to hope Data himself even considered incorporating into his own hardware, but would certainly revolutionize the science of it for humanoids.
