I have had both eyes done, several years back, and I would do it again. Otherwise, I would have been functionally blind. But there can be complications. I have had them all.
First, if the doc tells you not to do something, DONT DO IT!
Next, I would not schedule them weeks apart. I would wait about six months, to see what happens after the first one, but that is only precaution I would take from my experience.
I had one done, the worst of the two first, then waited for the second. (By the way, since I had been nearsighted my whole life, I had my surgeon put in a nearsighted lens. I was still working as a machinist and needed to wear safety glasses I couldn't wear over eyeglasses)
Long story short, the non-opped eye got much worse, and when I suffered a retina tear in the surgery eye, I WAS functionally blind. I scheduled the second cataract surgery as soon as I could.
As for what has happened since... I don't mean to scare you, but it is what happened to me (I do NOT blame my surgeon, it just is what it is.) I have had two cat surgeries, two YAG procedures (those were AMAZING, a Lazer treatment for a film that develops sometimes over the replacement lens) two retinal tears in one eye, one in the other, each requiring a Lazer repair, a detached retina in the left eye, that required two physical surgeries when the first one failed.
End result? I can see. So a win, I guess. Right eye can be corrected to 20/20 and is the one I use 95% of the time (like now, on my tablet). The left eye is sharper, clearer, can only be corrected to 20/50,but has a serious focal length problem that can't be fixed (I'm told). For example, if I look down at my feet with the right eye, they are five feet away (correct, as I'm 6'3"). The left eye says they are seven feet away. End result, can't read or see things close up without blurring, so I close the left eye (that's the one with two retina scars, a detached retina, two physical surgeries, three or four Lazer surgeries, and a YAG)
I have a friend, my girlfriends sister, who also has cats in both eyes, not nearly as bad as mine were, who Is delaying surgery as long as she can. Maybe from watching my experiences
As I said at the beginning, I would do them again, cause if I didn't, right now I wouldn't see.
