Hi, it's been a while since I've posted (years, I think). Sadly I need a bit of advice if possible. I've done a search and spent the last couple of hours looking through old threads, but can't seem to find a definitive answer (sadly, I think I've surmised what it might be). I left the RN about four years ago to read for a degree. I am now at the stage when I'm looking to re-apply and rejoin (all things being well - sadly a possible issue). A couple of years ago I was diagnosed with an astigmatism in my left eye. Yesterday I had a consultation with Ultralase to discuss the possibility of laser-eye surgery. Unfortunately, the original diagnosis was incorrect, and the tests and scans showed that I actually have keratoconus of the left eye. This is particularly annoying as until this developed a couple of years ago I had 20/10 vision in both eyes (I still do in my right eye, apparently) - that said, I have no idea if that actually means anything. So, I suppose my query (/request for clarification) is... does keratoconus of one eye serve as a bar to entry, full-stop. Or, is it possible to pass the appropriate sight requirements with correction or surgery. Or, does it only serve as a bar to certain branches. I sadly know that it would bar me from returning to navigating, which is a real low-blow for me (as I'm sure I'm just about the only person to join with the stated career goal of becoming a PWO(N)). However, would it be a bar to warfare on boats? Any thoughts that could be given would be greatly appreciated. Thank you.
