PING
It’s not just astronauts, they need to look a lot more into post cataract surgery patients. I did not have astigmatism before it, now I do. And am having huge fluctuations in vision that won’t stabilize to the point I can get glasses to correct the bad left implant, sloppy surgeon chose wrong lens and nicked a nerve too. I’ve always seen blurred out of from day 1. A decade later the second surgery was better, different surgeon, TOP in Memphis, but now I see at 2 focal lengths. Hard to correct vision that changes every day or two. And my Peripheral vision has been ruined.
You are not told Lasix causes Dry Eye Syndrome or that Cataract surgery does too.
