Surgeries, for what? eye injuries fucking suck arse. Nearly had one of mine melted out of my face by boiling hot corrosive alkalis that were highly water-reactive, but believed to be something else, after fucking pigs in an illegal raid on the house tampered with a bottle and removed a label. Got hit in the face after the bottle exploded violently and fired a jet of superheated caustic, corrosive viciously strong mixed alkaline wastes, including alkali metal amides and alkoxides straight through a hole punched through/partly melted through the bottle cap due to the intense heat and rapid evolution of a fuckton of ammonia pressure.
Was unbelievably fucking painful, ended up having to go to regular eye specialist hospital outpatient followup examinations for months afterwards, after the initial ambulance trip. Apparently came within ten seconds or so of being blinded permanently, or possibly even actually losing the eyeball altogether, but got off 'lightly' with 'only' having my cornea seared off a large patch of the front of the eyeball that was hit, I was really lucky that I managed to react so quickly, in getting to the tap and using my fingers to force the eye open so I could irrigate it for ages with a strong flow of cold water, while it was spasming due to the pain, forcing the eye closed and with the instant combination of searing agony and swelling I had to use both hands just to get the eyelids open to get the water to it.
Cleaned it out thoroughly, added a local anaesthetic after the washout, whilst calling the ambulance. Did however, given the other eye was unaffected, manage to both finish the actual chemical synthesis I had been working on at the time of the accident, during which the stream of corrosive steaming shit, actually gritty with bits of caustic soda and caustic potash, could feel them under my eyelids, had hit my goggles at an upward angle that knocked them up over my eyes, exposing the eye itself, like white hot sand under my eyelids, burning all the fucking way, but with the help of the local anaesthetic, managed to bear dimmed lights just long enough to finish the itself, volatile, corrosive cryogenic section of the synthesis I had been doing, pack up and stash the glassware so the ambulance crew wouldn't assume I'd been 'up to no good' and start with any judgemental crap, didn't do the workup for quite some time, couldn't bear light for a long time after, but the cryogenic, corrosive phase was reacted, stripped and neutralized, the glass setup broken down for storage behind a fridge temporarily and the workup to recover the product worked on at the time was left for when I could bear dim light again at night, rather than having to stay wearing an eyepatch and covering my head, with the lights off on a shitload of additional painkillers (oxy), which I'm still on, although I don't need the eye patch anymore though.
Eye wounds are the fucking pits. I've never had a bollock blown, burnt, shot off or parked on with a truck tyre, but short of that, I can't imagine anything more painful.
