It depends on the type of surgery. For example, in LASIK when the flap is being cut, one instrument (a microkeratome) is placed on the eye and suction is applied so that the eye cannot move. When the laser is applied, some surgeons use an eye tracking device, which monitors eye movement and adjusts accordingly. Some do not. In any case the patient must try to relax and not intentionally move the eye, so often a Valium is given before the procedure.
For other surgeries, such as muscle surgeries to correct a wandering eye, the patient is sedated, and the surgeon will want to be able to manually move the eye as needed.
I had surgery on my eye a couple of years ago (under local anaesthetic) so I know exactly what happens. They put some anaesthetic eye drops in your eye first, which kind of numbs it and paralyses it (feels really odd, but not painful or anything) and they also put a kind of clamp thing around your eye, which holds your eye open, and keeps your eyelids still. It feels odd but again it doesn’t hurt or anything like that.
Yep. Don’t worry, it’s not scary or anything, just feels a bit odd! :)
