Gaming help needed (with bribes)

Visual novels.
Turn-based strategies and maybe turn-based RPGs. Just not JRPGs, they are flashy as hell.
Most RPGmaker games could fit this.

You could try Ys Origin. Maybe Dawn of War but im not sure if that is suitable.

maybe Thomas Was Alone?

slow paced / low intensity ✅
light slower paced focus ✅ (it does have some focus requirements, but not a lot)
narrated text with unnecessary subtitles ✅
controller support ✅

ETS2 is an awesome game but unfortunately there is some reading involved to get where you're going, pick up delivery missions and so on. You would have to try it out in advance to see if it would work for you.

Maybe no games. Let your eyes heal and then you would have plenty of time to play games :-)

Maybe playing videogames is not the best idea... What about reading ebooks (zoom to make letter big enough)/listening to audiobooks? Boardgames? Roleplaying?
Or if you insist on videogames, adventure games with dubbed dialogs, like dreamfall

Little inferno
Racing games (like dirt etc.)
Civilization series (or any management game like that)

I think any walking simulator will be ok? Gone Home was a good game for example. Maybe some casual puzzlers like Quell? Sims, SimCity? Other suggestions: The Stanley Parable, Refunct, Her Story, Brothers - A Tale of Two Sons.

What do the doctors say what you're allowed to do?
I can imagine any kind of games will mean strain for your eyes.
Maybe audiobooks etc.?

Limbo, perhaps? If you haven't tried it, it's more puzzle than action, I don't remember it being actiony, although the "searching the screen for things" might be an issue.

Otherwise take a look at World of Goo perhaps?

bump

some point and click if the doctors allow you to play

How about adventure games? You okay with them?

Bumping with "thanks!"
(unfortunately i cannot help as i'm not a big fan of games that require low amount of focusing)

I don't think lego star wars is a good option in your condition...
Take a look at tabletop simulator and tabletopia.

As far as adventures go, how about Day of the Tentacle, Monkey Island, Deponia or Thimbleweed Park
Not sure if the text is big for you in the typical turn based rpgs, maybe you should give Divinity Original Sin a try or XCOM if you are more into squad tactic games.
Since you mentioned Trail in the Sky, there are plenty of JRPG games around, most notably the Final Fantasy series or those RPGMaker games.
Other than that global strategy games ("X4") like the Civilization series come in mind.

Life is strange maybe?
Episode 1 (out of 5) is free, so you can see if you like it before buying http://store.steampowered.com/app/319630/Life_Is_Strange__Episode_1/

Maybe The Swapper would be good for your situation. Nice puzzle game where you create clones of yourself to explore a space station. Dark colours, no time pressure, not much text mostly audiologs as i remember and a story about the unity of body and soul. 6-8 hours of playtime.

bump!

Trails in the sky SC is like the first one in almost every aspect so you should know if it suited for you.
From the games you mentioned Stardew Valley is perfect in this situation.
The gameplay is not fast paced and the text was big enough if I remember correctly. Furthermore it has controller support (did not use it)
I guess turnbased RPG or Strategy games would be good for you. Just look out for them (for example Civilization series)

Thomas was Alone
Bardbarian
Broken Age
Brothers: A Tale of Two Sons
DeathSpank & DeathSpank: Thongs of Virtue & The Baconing
DLC Quest
Mark of the Ninja
Inside
Limbo
Mini Ninjas
Total War Series Without battles, let AI handle them
Trine & 2 & 3
Don't Starve Together if you have friends who has it
Rogue Legacy
The Turing Test

I hope you have a successful surgery and recover soon ^_^
BTW I doubt about LEGO games, they are not exactly slow paced

Edit: After sending my comment, I read previous ones and found out you finished some of my games T_T

As much as I love Stardew Valley, I'm not sure I'd recommend it in this situation. There are lots of little things to pick up, and the mining portions of the game may strain your focus. Not to mention the text.

If you own any Nintendo hardware, one of the Animal Crossing games would be great. Very slow-paced, big text. You might need to pay attention when bug-catching, but it's entirely optional. Treat the critters as scenery and you'll be fine. You could also maybe emulate one of the older games, if you don't have a system from them.

Turn-based games in general would be great. Oldschool RPGs (emulation may be your friend here, though some of the Final Fantasy PC ports are pretty good), or turn-based strategy games. Heroes of Might & Magic springs to mind. I might suggest Advance Wars, but you might end up straining too hard when trying to differentiate between various unit types.

And speaking of Might & Magic, they also have a puzzle game with various ports (including one on Steam that I have yet to play, I mostly played my friend's DS version) called Might & Magic: Clash of Heroes. It's also a turn-based sort of thing, rather than a fast-paced thing like Tetris. There may be other puzzle games in a similar vein, too.

I think looking backwards would be a good call for the types of games you're looking for. Pixelated stuff, at a low resolution, blown fullscreen with dosbox etc, is given to have large text and easily discernible features, putting little strain on you to see details.
Dune (1) - An old click-to-move adventure explorer. The pace is exactly as fast as you care to click ahead, except for some stategic aspects lategame, that progress at a crawl. Definitely a low-intensity game, with an intriguing story.
The Lost Vikings - It's a puzzle-game, dressed up as three vikings with each their own special ability, that you need to switch around to control, one at a time, to solve the puzzles.
Pokemon R/B/G - A classic. Regardless of the dressup as cutesy childrens-entertainment, the gameplay and strategic depth is solid and always nice to play.

If you really can't stand stuff that's as old as that, some newer titles i think you could relax to would be:
Peggle - the epitome of casual games, it's nevertheless entertaining for a while, and doesn't require much focus to just shoot randomly around.
World of Warcraft - By now the game basically plays itself, and everything is neatly colorcoded, so even halfblind and on painkillers, you can't fail, and the game WILL make you earn xp regardless of how much or little you focus on doing anything.
Prison Architect - Sim Prison. Build your prison, and watch all the super simplified models scuttle around. Easy zoom function also means that you can always find the magnification level where you can easily see what you want to see.

Dark souls;

More about patience and patterns than rushing through
No sniping required, just get a big stick an pancake everything
YOU DIED is in pretty big font
Better on a controller

I don't really think the LEGO games are a good choice...lots of herky-jerky screens, blaster fire...you have to be fast-moving (relatively) to get through certain scenes. And if god forbid you try co-op, the screen-splitting and unsplitting, then resplitting-- totally messes with your eyes.
