Default Cataract Surgery

Looks like it's time to get my cataracts fixed. There's been a small
one in my right eye for five or six years and nothing in the left. In
the last six months vision in my right has gone down the tubes. The
doctor says I now have three in the right eye and the left is almost
ready too. I've been nearsighted (-5.5/-3.5) all my life.

Any suggestins for the implant? Implant for distance and do reading
glasses, or stay nearsighted and do distance lenses? My first impulse
is to go for distance since I would still need safety glasses for most
of what I do.

Of course the glasses will come from Zenni 8

Have you investigated the new models coming out
IIRC with some type of variable correction system?

Not variable, multi-focal. You see multiple superimposed images of the
world, each focused at a different distance. Of course, and this what they
will try not to tell you, you also see just as many multiple superimposed
UNfocused images. The idea is that your perception can sort out the
focused and unfocused information and selectively perceiving the focused
information and ignoring the unfocused. This is kind of like seeing
through a cataract to start with, where you have a focused image but
superimposed with a hazy glare, and you try to make the best of it.

Thus the multi-focal principle sacrifices acuity for convenience.

One also has to be skeptical as these are patented products being heavily
promoted at a multiple of the price of conventional IOLs.

Varilux? RUN AWAY, RUN AWAY! If you look straight ahead, they work
just fine. If you use any of your peripheral vision, turn your head at
all, move around, change focus a lot, or drive, they suck the big one.
80% of the lens is totally uncorrected. I fought them for two weeks
and made the optical office make REAL bifocals for me.

Varilux? JUST SAY NO!

^^^^^^^^^^^^^^^^^
Furthermore, the progressive focus eyeglasses work very well for most
people. My son says it took about a week to get used to them.

This strikes me as a prescription (get it?) for a headache. No way.

My wife had hers done within last two years. She has distance with glassess
for computer and reading (bifocals). She seems very happy. Moreover, she is
very glad she had the surgery when she did.

Good luck.

I was extremely nearsighted (~ -10) when I had mine done two years
ago. The ophthalmologist said he aims for 20/20 distance, but tries
not to overcorrect, since a little nearsightedness is useful, if not
perfect vision. (Farsightedness is mostly inconvenient all the time.)

Two years ago, the surgeon recommended NOT getting the multifocal
implants. The group had done some at patients requests, but some
patients weren't satisfied with the outcome. The optometrist who
makes my glasses said that he'd had some of those patients after
surgery and making glasses for them to see better was problematic.
My recollection was that they worked OK for people whose goal was only
to see well enough to read a book and distances well enough to play
golf, but for anything requiring sharp vision, they didn't work very
well.

Discuss the variable lens implants with your surgeon. Maybe they've
improved, but do a lot of reading and checking to see if they've
improved.

About a year after the cataracts I got a deal on laser surgery (Lasek,
not Lasik) and had that done to bring my vision to 20/20 and get rid
of the astygmatism. Very worthwhile and a big improvement. I haven't
seen like this since I was 12 years old - except I need reading
glasses to see up close - but hey - only $3 a pair at the local
bargain store and I've got them scattered all over the house.

Oops. I thought the thread had drifted to (or back to) glasses.

They're not variable. They're multifocal. It is a holographic lens with
two fixed focal points. This is a genuinely novel device in optics,
whether or not it is a good thing for an implant. Think of a Fresnel lens
where the alternate rings focus at alternate focal points instead of the
same focal point. This is unlike any other lens made by forming a simple
curved surface.

That's 1.25D, not x. The number is the power in diopters. It's not a
magnification.

Kabow

I had cataract surgery a few years ago. One eye one week and the other
eye a few weeks later. All went well.

Start by asking around everywhere you are able to until you find a
doctors name coming up regularly. Ask older folks as cataract surgery
is an old folks thing. There is probably a web site for this and where
I live in Tucson there are lots of both newspaper and TV ads from lots
of doctors who do cataract surgery. Keep up the asking until you get
results.

In my own case I found that my left eye was seeing yellow al the time.
When looking at the stars my left eye twinkled and my right eye was
fine. The headlights on the car were yellow. So have your eyes
examined as often as needed to be sure you have determined the exact
difficulties or symptons. Don't skimp on examinations. Repeat as
necessary. Be sure to know exactly what is wrong.

I never needed any glasses but for reading and closeup. I have the
generic implants and the doctor never considered anything else. When
I visited his place the nurse showed me throughout the building.
Answered all may questions and invited me to return for more visits
before making up my mind. In my case the recommendations for the
doctor were 99%. I am sure there are others as competent but his
personality meshed with mine and I went with him. Took me a few weeks
to schedule the first eye and after that all went as planned. Be sure
to have someone to drive you home after each surgery. I did not drive
for a week after each surgery. I do tend to be more cautious than most
but I did not want to have any future liability problems.

Write back if you would like.
and the doctor

I've had both eyes done; the left one just a year ago and the right one
in March. I had extreme long sight before the surgery and needed glasses
for everything: varifocals for normal use (driving, reading, walking,
etc), and special high-power ones for close-up work (I make jewellery).
I used contacts for sports and tried both types of multi-focal in a vain
effort not to wear glasses. I couldn't get on with either type: the
contrast with the refraction/diffraction type was too low, and the
toroidal type was just bad - for me. There was no way I could make
jewellery with them

I wasn't given the option of multi-focal implants, but would not have
chosen it after my experience with the contacts. I chose the 20-20
distance option on the implants and haven't regretted it. I don't have
to use contacts for sport but got so tired of putting on glasses for
reading that I've reverted to varifocal glasses for normal use (the
distance prescription is about zero); they are photo-chromatic so double
up as sunglasses too. I still use my special glasses for close-up work
and they work even better than they did before.

Just my experiences.

I had both eyes done 4 & 5 years back. I went with distance, and
transition lens, (no-line) bifocal. Same reason, I wear safety glasses much
of the time. I'm happy with my choice. Machinist by day, cobbler at night.
Wish my woodworking skills were as good as my machining skills are.

I was also shortsighted (-3.5/-3.0) from about age 25 and wore contact
lenses for more than 30 years, starting with the hard plastic
(horrible but better than glasses) through bi-focals ( could not get
used to them ) and finally long life lenses, with left eye set for
reading and right for distance. I went for laser surgery but my
eyes were unsuitable as I also had minor cataracts. The surgeon
replaced both lenses with plastic about 6 months apart over three
years ago and I have had no trouble since. My eyes were set for
distance vision and I now have 20/20 at over 3 metres. I can read a
book at arms length without reading glasses but get tired quickly. I
find it more comfortable to use a range of lenses depending on
distance, +1 for metal & wood work, +1.5 for computer screen at arms
length, + 2 for my laptop and +3 or +4 for model making. This makes
my close vision clear, but I do need plenty of light and do not
attempt to read without a desk lamp or do metal/wood work without
additional lighting unless in sunlight.

I suggest that you do the same as me, set for distance, as most of the
time you are not reading or doing close work and will not have to wear
glasses. Most relatively close tasks like eating etc. do not
require glasses as you do not need concentrated vision as in reading.

You can get prescription safety glasses but I prefer ordinary glasses
and a face mask, especially for the wood lathe, router and sawbench.

Living in a very rural area we were unable to find anyone who
was familiar with them. She opted for reading glasses as
well.
It turned out well: She just got her new drivers license, with-
out any eyeglass restriction, for the first time in her life.
