I had one Crystalens in right eye 1 month ago and still wear a contact in left eye. My first 3-4 days post op were a little uncomfortable, the distance vision was blurry at first, my eye was dilated with atropine so I had lots of glare, fuzziness, discomfort from bright light, etc. I didn't drive until 6 days after surgery. By now my distance vision is excellent, the lens is working at all distances except fine print, I still have some adjustment issues with my contact lens eye but you will not have this once you have two Crystalens eyes. But there is a definite adjustment period with Crystalens.
