After my LASIK surgery not only did I get dry eye I have also noticed quite a few floaters that definitely weren't there before. These floaters are quite faint and can't be seen under a slit lamp. They are mostly annoying when looking at a PC screen or on a sunny day. I've been checked for retina tears and don't have any.
My question is are dry eye and floaters in LASIK patients related beyond being caused by LASIK? What I mean by that is I've read the more short sighted you are the more likely you are to have floaters(regardless of surgery). I've also read that the more short sighted you are the more likely you are to suffer with dry eye after LASIK due to more of your cornea being cut away which causes nerve damage so your glands(lacrimal & meibomian) don't receive the signals they need correctly from your brain.
I know some think that the floaters in LASIK patients could be caused by the high pressure of the suction ring used to hold your eye in place, but their have also been many LASEK patients reporting post operative floaters. I'm thinking could the likelihood of post LASIK floaters be more down to how high your prescription was pre-surgery? I've seen lots of posts on various sites about having both floaters and dry eye or only having dry eye post LASIK but I can't recall seeing too many posts about having just floaters post LASIK with no dry eye. Also I know five people who had LASIK with no dryness or floaters but they were all -2.25 or under.
I've also been told by an Optometrist not connected with where I had my surgery that the vitreous gel in people who are more than -4 is significantly weaker and more likely to become detached than those under -4. My right eye which is the one which is giving me the most trouble in both terms of dryness and having more floaters was -5 pre LASIK. My left eye which has had a lot less dryness issues and has hardly any floaters was -2.75 pre LASIK.
Sorry for the long post but I would like to know what other people think about this possible connection between prescription, LASIK dry eye and floaters.
