Actually, it's not all that bad in the grand scheme of things, but the wife, the kid and I are going to have a rough 24 to 48 hours sometime soon.
The kid was diagnosed with Entropian, which is a "very rare" inward cruving of the lower eyelid. It can be mildly irritating to her, but can leat to scratching of the cornea if left un-corrected. The most successful treatment is a 15 to 20 minute out-patient surgery to correct the defect. The results are usually permanent, which means that we won't have to do it again. The doc says its genetic, but I think it may have more to do with her overly chubby cheeks.
From everything we've found out so far, the recovery time is pretty quick (12-24 hours), but that's in "adult time". I can't imagine that a 5 month old is going to be highly tolerant the post-op pain, eye patches, and antibiotic balms and salves. Not to mention there's probably some sort of eating before sugery restriction.
Of course, we know all of this now. There's always that horrible period between the time the doc says "surgery" and you find out that it isn't a really big deal.
