Also after Yag it is quite common for the crystalens to loft forward slightly changing your RX. Whatever you do dont let them talk you into Lasik!
Sounds like your vision is changing. almost like you are ever so slightly nearsighted. I also had this happen after crystalens. In the Dr office they always said I was plano (no correction needed) but distance always looked fuzzy. I ended up buying some glasses from a discount site on the web, at $7 each I could try some options. I found a -1 diopter correction did the trick.
Hello and hope you are doing well.
Please post this query in the related forum. Surgery again may have complications. If repeated laser therapy helps clear the membrane, this may help to restore vision. Check with your doctor.
Hope this helped and do keep us posted.
