I have the same concern as you. Have not had either eye done yet. I am near siighted. Cateract much worse in my dominatn left eye but they want to do my non dominant right eye first. I am thinking of a accomodating lens in right eye and maybe same in left, but I am scare dto death of not being able to see close. or my computer. i also wonder why majority of peoplle get both eyes for distance
After cataract surgery, the spectacle power can fluctuate but generally stabilizes at about a month post-operatively. When you have your other eye done, it can indeed be set for a nearer focus distance.
The calculations for lens power are not 100% accurate all the time, but they can give results that are very close for most people.
They are less accurate for people with very long eyeballs (high degrees of myopia/shortsightedness) and very short eyeballs. For these eyes, special adjustments or different formulas may need to be used to give better accuracy.
Thanks very much. It helps.
Re question 2;
http://vision.about.com/od/contactlenses/ht/Eye_Dominance.htm
I seem to suffer from the same exact problem as described by HapKP. I have been strongly myopic (approx minus 7 D in both eye) for last 30 years. Age 55 years. Left eye operated for cataract and set for distance vision with monofocal IOL. I am software professional and now can not see computer and near distance without glasses. Want to be consider all options before right eye surgery. I have two questions:
1) I have been near sighted (myopic) for last 30 years. Is it a bad idea to have near vision correction in both eye during cataract surgery. I understand left eye already operated and set for far-distance vision and my options are limited, but why surgeons prefer to insert IOLs for distance vision by default, it there any merit in this that surgeons see in correcting for far-distance? Conversely, is there any demerit is correcting both eye for intermediate or near distance. Your views, please.
2) Please suggest how to determine dominant eye.
How did you resolved your problem with non-dmonant eye set for distance? What is the out come? I have the same problem as you. I also requested for mini monovision and my dr gave me near vision for my dominant eye. I am very angry and confused. (I resend my message because I made an error on your name and don't know if you would get the message. )

Anne102,
Thanks. Yes, my optometrist suggested the trial contact. My opthamologist did not think it was really necessary because, as both noted, I appear to functioning with monovision already, since the cataract surgery on my left (non-dominant) eye removed my astigmatism. I had my one week exam. The left eye now has zero astigmatism and 20/25 distance. He didn't tell me my near vision, but it is beyond the range of fingertips without the help of right eye.
Hap
Would it be possible to have a trial with a contact lens in your dominant eye to determine how you might adjust to closer vision with that dominant eye.
It might even be possible to try several different distances to see which you prefer.
I am likely to have cataract surgery in the future and my optometrist said that I should have a trial with contact lenses first if I want monovision.
In addition, I have done a lot of online research, and have noticed that several eye surgeons have said that that they feel it is ok to make the dominant eye with closer vision for monovison.
With myopic shift from cataracts, I no longer need reading glasses for near and intermediate (computer) use. Would hate to have to go back to two sets of reading glasses all the time. Being able to drive without glasses is not important.
I can answer your last question....if you don't get torics to correct your astigmatism, you are going to need glasses for everything...distance, midrange and close...
Thank you again, Dr. O.
So getting my doc to exchange my Toric IOL set to distance in my non-dominant Left eye to one set for near is the ONLY fairly certain way for me to move forward to getting mini-monovision so I can see SOMETHING at reading distance? Leaving the Left eye set for distance & getting my very dominant right eye set for near, MIGHT work, but it's a long-shot. Right?
What if did not get my astigmatism corrected in my right eye, but simply had the basic cataract surgery but no Toric lens in my right eye? My astigmatism in my right eye is helping me read without readers with only the left eye cataract fixed.
Hap
Thank you for your kind reply.
I'm a bit confused though about your second paragraph: "I have seen patient that the dominant eye was set for near and I have not change them when they had cataract surgery." If the lens can be changed from near to distant, and it's important for the dominant eye to be set for distant, is there a reason you would not change the lens on the dominant eye to distance?
Or perhaps I'm completely misunderstanding.
Ask the doctor to exchange the IOL. I do not believe you change dominance easily, especially when very dominant in one eye.
I have seen patient that the dominant eye was set for near and I have not change them when they had cataract surgery.
Dr. O.
I have had other patient who developed a cataract first in the dominant eye and became non-dominant due to the cataract. In these case I set the original dominant eye for distance.
