Vision worse after cataract surgery

I am assuming that Tecnis MF is one of the multifocal lenses made by Tecnis.

I am also sorry to learn that you also have an issue with the multifocal lense. Am not sure why in spite of a very large number of people having night vision issues as well as less-than-desirable day vision with them, the surgeons are still recommending and using them for patients. (I had experience with the multifocal contact lenses many years back, hated them, and switched back to the regular contact lenses within less than a week).

3 days after surgery is way too soon to tell, so yes it's normal (plus everyone is different and some people have worse experiences with one eye compared to the other eye). There have been people who have problems with multifocals, but like I said, it's too soon to tell if it's the lens or not.

Did you get a monofocal or multifocal IOL?

I also just had my first cataract surgery in my right eye, 2 days ago (Tue around noon) with a Tecnics toric monofocal IOL for my moderate 3D astigmatism.

The first day vision was cloudy/hazy in the right eye and worse than 20/50, but the eye was highly dilated all day and night, so even indoor lighting bothered me. I also noticed bizarre rings around many lights like blue LEDS and outside at night even around the moon. Should have taken a nap the rest of that day.

After a good night's sleep, I awoke the 2nd day to much better vision in the right eye. The haziness was gone, the strange circles around some lights was gone completely and pupil size has gone down almost to normal.  Vision improved to around 20/40, sometimes 20/30 yesterday.  I had my next day post-op checkup that day as well later in the day and said everything was looking good and to expect variations in vision for up to a few weeks before it stabilizes.

Today (3rd day) again I awoke after a good night's sleep to vision improved, this morning I was seeing 20/25 and at times 20/20. So it appears I must be very close to my target just under 0D for the right eye and hopefully will stabilize at the best vision I've had for short periods today.  Seems like I get a big improvement after each night's rest and no change during the day other than within the range of variation.

From what I've heard every eye is different and how long it takes and how the cornea heals will vary, so could take a few days or weeks.  Best to have patience and get extra rest.

Yes, I have Tecnis multi-focal lense in right (dominant eye). Saturday, 5 days post-op, vision not as clear as left eye with glasses. I temoved right lense from my bifocals. Vision is brighter and whiter than left but significant halos still present atound night lights and writing on tv screen.
