what do you use your eyes for more? Near or distance? If you choose
distance, youll need reading glasses for anything 1 meter away or less
and things will be start blurrying at 2 meters. If you want to keep
your computer distance vision clear, opt for a 1 to 1.5 diopter
undercorrection. I think its better this way because youll only need
reading glasses for reading fine print, but on the flip side your
distance vision will be 20/40 or just a tiny bit worse. Youd only need
distance glasses occasionally and to drive. I know this lady whos
naturally myopic at -1.25 and shes very happy she can see well enough
to read at arms length and see well enough in the distance not to need
glasses except for driving and sometimes watching movies. My brother is
also -1.25 and doesnt need nor wear distance glasses except to drive.

The way I think of it, if you choose to be plano, you wont see a thing
from near and if you get overcorrected at all, youll see blurry at all
distances. Asking for an undercorrection greatly reduces your chances
of overcorrection. Youll have the benefit of seeing from near and only
very slightly blurry in the distance. Unless you must have perfect
distance vision for your activities, choose the undercorrection and
smile at not needing reading glasses :)

Measure the typical distance to your computer screen and tell him that's
where you want your best vision. Given the opportunity to choose, most
people would prefer a less nearsighted prescription than -3.00. If you've
been pulling the monitor close enough to see without glasses (eg ~12")
consider moving it back to 20".

If the implants make your distance vision perfect, you will certainly have
trouble at computer distance and closer.

Presumably the surgery is required because your vision is cloudy at all
distances. That will certainly improve, but there is still the problem of
focusing at different distances. Choose the "working distance" that _you_
use most. If your monitor is at 22", you'd want a post-surgery refraction
of -1.75, and your "driving" glasses would be perhaps 30% thinner than
your -3.00's.

Multifocal implants aren't as satisfying as we might wish, and they cost
more.

Been there, done that---sorta.  Just went through the IOL implants in
last month,  though I was far sighted (+4.0) vice near sighted.  I'm
going to give you my opinions, based upon my research, and experience,
and I am an online news editor, not an OD.  There are some good ODs
and MDs  reading this group and they can certainly provide you with
their expertise.

Before we get into this, the biggest issue you will need to confont is
how you feel about glasses.  E.G.  I have worn them most of my life,
and I still do.  If you are tying to get rid of glasses rmember that
this is not cosmetic surgery to enable you to do so.  But, if glasses
are acceptable to you, then accept them. (Carrying them, putting them
on, taking them off, peering over the top, would drive me nuts - I
expect them together with the condition pf my eyes, to afford me the
best vision possible at all ranges/conditions---one pair---all of the
above---all of the time)
My reccomendation is go with the "far" option.  He will probably bring
them in just under perfect to avoid over-correction.  You glasses will
handle the rest.

Probably not if you go for the "far" option
And how important is this???  It depends on how you have the IOLs set
up.  But, according to my reading of your message, you have lenses
with a correction in them now---or do you only put them on for
distance viewing.

No one can answer that but you.  Is that what you use your glasses for
now?  

Looked at them, did not try them.  My research revealed that there
were enough problems with them that some folks were opting to have
them removed - enough to have the number generate a statistic.  So, if
something drives you in this direction, have your eyedoc guarantee you
that he will replace them, free of charge, if they don't work for you.

For lights at night, some folks yes, some folks no.  In most cases
research says  they tend to go away after a time. I'm experiencing
some with nioght driving.  Nothing that would prevent me from doing so
(My last implant was done about 6 weeks ago.) There are ultraviolet
filters available in lenses by several mfgrs.  They will help siome
and will help with night vision.  Might as well opt for them.  I did

You're welcome.  Remember free opinions are worth what you pay for
them,
BTW, if you have an astigmatism problem, in there somewhere, I would
be glad to provide you an opinion on procedure known as the LRI
(limbal relaxing incision)  Folks in this group know it won't be a
good one.
 Be well!!!

I got about 1D nearsighted in each eye.  If I had it to do again, I'd choose
that.  It is good for almost everything, but night driving and reading take
eyeglasses.  If my computer screen were at 40 inches (~one meter), it would
be good without eyeglasses.  23-in.TV at 10 feet is acceptable without correction.
Recognizing faces across the street is problematic.

The outcome of lens replacement is not precisely predictable.  Astigmatism
may be changed, or be introduced.  In my case, there was a stated uncertainty
of a half diopter sphere on account of uncommonly long eyeballs.  I learned
that from the tech who measured.  The surgeon was unwilling to call the shots
or consider requests (very frustrating and anxiety provoking!)  Probably
your surgeon will shoot for something in the mid range.  Hope you have such
good luck as I did, so as to not need glasses for most things.

Walgreens readers (+1.25 D) do fine for me, and are no worse than
"add 2" to my prescribed numbers.

I do notice objectionable flare, and halos when the corneas get unduly dry.  
Dry-eye was increased by the implant surgery, more in one than the other.

If you keep the same Rx post surgery you'll be able to read without glasses. You
will need glasses for distance and computer.

Maybe. You will see very small print without glasses better than you will see
the same size print with glasses if the post-op Rx is more than -2.50.

If the psot-op Rx is -1.75, screens at 23" will be clear without glasses. You
will need glasses for distance and normal reading distances.

That's how I plan to do it when my time comes.  

A benefit for one person is a PIA for another.

I've heard more bad than good.

Ditto.

Hope this helps
