Hey Liz
only just seen this, so not sure how much use by input would be, but from our surgery lectures at uni (so this is theory, not practice as not seen one yet) when they do eye removal surgery they either
(a) stitch is closed but insert a drain - you're probably seen one, like a piece of tubing, that allows the pus or any other fluid collection, to escape from the wound. This is because the socket essentially becomes 'dead space' and even with incredibly aseptic surgery its easy for them to become infected and fill with pus as the immune cells can't penetrate to do anything about it.
(b) leave it open or partially open - this is for the same reason, but it allows the socket to drain naturally, and the tissues heal by 'second intention' i.e. granulation tissue naturally forms over the socket tissue, then epithelium. the wound naturally contracts down and the eyelids heal together, which is more likely to be lumpy but is naturally resistant to infection.
So, if it was left open or partly open they may have gone for the second option, but this does normally require very intensive nursing, for obvious reasons, so would normally be kept in hospital.
It doesnt surprise me that so many eye removals have ended in infection as its really hard to prevent anyway, especially as it sounds like most didnt have drains fitted? :?
