Still need glasses after Cataract surgery
Posted , 7 users are following.
I had cataract surgery done for both my eyes by the same surgeon. For both I had opted for Monofocal lenses for the distance. First it was the left eye done about a year ago. My vision was not clear first 3/4 days after the surgery and then very unstable for about a month. Fortunately it settled down and I could see things in the distance clearly without needing glasses.
Then I had the right eye done about 6 months ago. This time I could see things better from the 2nd day but it was a bit blurry. The surgeon said it would improve after a few days. It never did. In the end I have to wear prescription glasses for my right eye. It is not very much but I need it. The sphere value on my right eye in -0.75. Even with this correction I have somewhat of a blurry vision.
My surgeon gave me this reason for the blurriness. She said the IOLs are not custom made to be precise and it is made for a range. In my case it fell somewhere in the middle of the range for which the IOL was chosen. That is the reason I am not seeing as well I should.
I am trying to understand it this is the case or do I have any other recourse.

Unfortunately cataract surgery is not super precise… at least not reliably precise. Although a .75 miss (if the target / prediction was 0) is not great and usually you can expect a better result than that. It would help, as Ron says, to know what the actual prediction was and with what formula along with final refraction of the eye with sphere and cylinder. That information would tell you more precisely how far off the mark you ended up.
.
Options are glasses, contacts, piggyback implant or LASIK / PRK / SMILE. That said, those laser procedures are not 100% accurate either. You may be told that .75D is too small of a correction for them to be able to achieve / promise.

Ron and David have given you great information, but for what it is worth I will throw in my 2 cents. I had cataract surgery done and my outcome is:
RE -0.75 spherical equivalent
LE -0.125 spherical equivalent
My left eye is the same as yours and my right eye is a bit more myopic than your right eye. Keeping in mind everyone is different, I get 20/20 for each eye when tested and I can see fine from approximately 2 feet to infinity. You say using your right eye you see clearly at 2 to 3 feet and then everything gets blurry and glasses help somewhat, but not as good as the left eye.
I would suggest taking Ron's advice and asking your eye doctor if you have PCO. My eyes after cataract surgery were fine for 2 weeks and then I got PCO. Street signs got blurry to me and things in the distance were blurry. Most people think PCO doesn't happen for a few years, that is not always the case.

Actually, I had the surgery about 6 months ago. I have had this issue ever since surgery was done. The doctor has done a check about a month ago. She did not mention PCO.

The Tecnis 1 lens fully corrects spherical aberration to zero by building in a -0.27 um correction to the lens. Providing the lens is perfectly centered in the eye and not tilted it can provide very good vision. However if it is not, then it has a lower tolerance to a lens not perfectly inserted. So, you could ask if there are any issues with the lens placement, but unfortunately at this point there is not a lot you can do about it.

you were plano before cataracts for distance and needed +2 readers.
your surgeon set both your eyes for near vision.
is that what you asked for????
you will need glasses for distance. about -1.75 both eyes. your near reading vision should be glasses free.
normally plano folks like yourself are made plano for distance as you were used to readers anyway. its an unusual choice.

"I had cataract surgery done for both my eyes by the same surgeon. For both I had opted for Monofocal lenses for the distance."
Does this mean you asked for distance vision, but received lenses set for near vision? So your distance vision is blurry without wearing eyeglasses. Or did you ask for near vision? Did the surgeon understand what you wanted?
