OK, so I’ve always assumed that Kurt saying in “Michael” that Blaine had a scratched cornea was a case of misspeaking, since surgery isn’t required for a scratched cornea, and one wouldn’t keep a kid out of school for two weeks.
So I thought it might be a corneal laceration, but today I’m reading up on those and it looks like surgery for corneal laceration would probably have happened sooner rather than later (i.e., Blaine wouldn’t have returned home from the hospital before having the surgery). Surgery may have been delayed if the doctors first tried a healing contact lens or tissue adhesive and those failed to heal the laceration.
And he may have been out of school for longer if he had to travel to a distant city for the procedure (or his parents wanted him to traveled to a distant city for the procedure, because of the reputation of a particular surgeon, for example).
So, yeah, this second scenario is conceivable, but now I’m just curious if maybe he had to have a corneal transplant. I’m in a medical database right now, so I guess I could look corneal transplants up right now, but instead I’ll just throw out this random question to tumblr.
