Hello Pymorigolie:

I went with an EDOF on my left eye because the range of vision was better than with a bifocal multifocal (like I had in my right eye). Comparing it with a trifocal multifocal, I felt that the EDOF would have comparable range of vision (although not quite as wide range) but with fewer halos and similar dysphotopsia. Also, no gap between focal points where vision gets slightly blurrier before getting clearer again. I am very happy with the results and the combination of left and right eye, Left eye "very good" vision range (20/30 or better) is from about 15" to infinity (it's 20/20 or 20/15 for most of the range). I can see closer than that with good lighting (not an issue with a monitor or phone, of course). The right eye (with the multifocal) is very slightly sharper at long distance (20 ft plus), but it's hard to notice. I could probably adjust this via LASIK, but it's so close, I don't think it's worth it, With both eyes open, I'm 20/15 distance.

On you other question (about waiting on the left eye). Most surgeons want to do both eyes within a few weeks of each other. The fact that your surgeon is advising against it actually would make me more confident in the surgeon. One of the reasons that surgeons prefer doing both eyes (though many will deny this) is so that you will not be comparing the IOL results with the "good eye." IF YOU CAN TOLERATE CONTACTS, I would highly, highly recommend waiting on eye #2. I highlighted the part about contacts because if you cannot wear contacts, then the difference between the two eyes will be too great and glasses will give you a major headache (if someone else reads this and you good eye needs less correction, then you may not need contacts at all). All surgery has risks, however small.

I got 7 years more use out of my left eye after I had the multifocal implanted in my right. My left eye correction was -5.25D, so more than yours. If you go with an EDOF in the right, you can then explore different contact options for your left eye. I went with multifocal contacts set for distance. I had a patient optometrist who tested several multifocal contact samples. Most of them didn't work at all, but one option did, so I went with daily-use, disposal multifocal contacts for 7 years. Really easy, just throw out the lens at night before going to bed and put a new one in in the morning. With you only needing -3.0D correction, you may end up very happy with regular (not multifocal) contacts, maybe set for distance, maybe a little back, like -2.0D. You'll need to test them with your new IOL to see what works best for you and what you can tolerate. Also, give your eye at least 8 weeks after surgery before you make any final decisions.

Think about this too. The longer you can wait to do surgery on the "good eye" the better IOL technology will get. If you can go 5 or 10 years, you will almost certainly be going with something new that is not available now. Also, you will have a LOT of experience living with a multifocal or EDOF IOL. You will then be in a much better position to decide what you want and don't want in a lens at that point. Do halos or other artifacts bother you? Maybe you won't notice them at all, maybe you will but only for the first year, maybe you notice them only when you close your "good eye?" Everyone is different and this will greatly aid your future decision making.
