I reviewed my assesment with my doctor and this us what he wrote.
The patient also understands that there is still a risk of needing glasses to optimize distance vision as well as the high likelihood of needing glasses for reading.
He also wrote Aim Plano. If he feels I will most likely need readers why would he put Plano? Am I correct that plano is 20/20 ? Is this standard for al doctors to put down on record?

What lenses are you getting?

In theory you should get good distance vision (plano) and good reading vision with the PanOptix. It would be normal to target plano (-0.25 D or so) for distance. Then you depend on the multifocal properties of the lens to give you the reading vision. If all goes well then you should see well in both distance and close enough for reading.
.
The issue is that it doesn't always go well, and there can be some error in the calculation of the lens power. I can't remember if you have posted before, but do you have any complicating factors such as high myopia, or have had previous Lasik treatments? They can make it harder for the surgeon to be as exact in determining the correct lens power.
.
If there are no complicating factors then I think the surgeon is just covering his bases, in case things do not go as well as one could wish. We all take that kind of a chance going into cataract surgery.

I do have high myopia but no prior lasik. I do have floaters in one eye. If they dont get the correct lens power, can it be fixed with lasik afterwards?

Yes, it could be fixed with Lasik, but the hope is not to need that. How high is your prescription for contacts or glasses? I think until you get up into the -9.0 or so range, they should be able to make a good measurement of needed power.

my latest auto refraction is -10.25 for the right and -10.00 for left.. It says on my report the glasses I am currently wearing are -11.75 and -11.00

Yes, that is up there. If you want the most accurate power selection I think I would be looking for a specialist surgeon that does high myopia eyes. The other thing to consider is that if they miss on power then multifocal lenses like the PanOptix are harder to correct with glasses.

I don't understand this last sentence.

A monofocal IOL lens has a single power, and if they miss on that power, a single power correction with eyeglasses or a contact is all that is needed to fix it. But, a monofocal will require reading glasses for close vision, even if they get the power perfectly.
.
The PanOptix is effectively a tri-focal lens, so you have three powers to correct for if they miss. It is still possible that a single power correction or a progressive eyeglass correction will correct it. But, due to the three effective powers, it is less likely that all distances will be good. In short it is a complicating factor.

thank you for clearing that up
