as a followup on my one crystalens patient (monocular implantation about
a year ago). Still zero to .25 D. accommodation. Now an increase in
her astigmatism from .75 to 1.25. I still think it's a terrible lens.

The term presbyopia has no meaning post-cataract surgery, since there is
no accommodation regardless of the age of the patient.

In other words-undercorrecting one eye,

not both, and perhaps more than "slightly", depending on how bad the
presbyopia is.

Undercorrecting is also meaningless in pseudophakia, just like
presbyopia, unless you mean putting in too weak an iol, which would be
nonsensical as it would leave the person hyperopic. I suppose you might
have meant "overcorrecting" where the iol is stronger than needed for
perfect distance vision, which would indeed leave the eye myopic.

accommodating eyes, that would indeed be a great development!

It would indeed be a great thing. So far they don't work well at all.

if you had asked to be undercorrected slightly you wouldnt need reading
glasses much, unless you want to read fine print or see something close
up. A slight undercorrection will also mean youll only need glasses for
driving and maybe some other occasional events. Less annoying than
carrying readers all the time and inserting, removing, inserting,
removing them. some people just wear bifocals instead.

Well, if one is only slightly presbyopic, that perhaps would work. For those
of us more presbyopic, I doubt that a slight undercorrection in both eyes
would serve for both distance and near vision.

I suspect that IOLs after cataract surgery are often prescribed monovision,
just like contact lenses often are for presbyopic patients--one eye better
for distance, the other for reading. In other words-undercorrecting one eye,
not both, and perhaps more than "slightly", depending on how bad the
presbyopia is. It is a compromise of course, but one many make in order not
to bother with reading glasses. My brother had Lasik done monovision--one
eye undercorrected, for near work.

Yet, the idea of accommodating IOLs certainly sounds like a better solution,
if they really get it to work well. From what I;'ve read (I think here), it

Hi everyone,

Hi Beverly....

Quote:
Background: In December 2005, I wrote asking for suggestions on increasing
the IOP after trab surgery because my pressure was so low (1). Thank you
to those of you who replied.

I wasn't subscribed to this group at that time.

Quote:
I am now 6 months out of surgery and have had
revision surgery in April 06 that included not one but two patch grafts in
an effort to increase the IOP.

That's a pretty delicate operation.

Quote:
Bottom line is that my pressure is still
around 4 and doesn't want to come up.

Yuk.

Quote:
The problem is that I have extremely
blurry vision and the macula is folded or wrinkled and I now have hypotony.

I looked hypotomy up on the web, but didn't find anything that I thought
might be useful. I've crossposted this reply to sci.med.vision in the
hope that someone there might be able to help.

Quote:
My vision went from 20/20 prior to surgery to 20/200 after surgery in that
eye.

Ouch! That must be very frustrating for you.

Quote:
In order to get rid of the folds in the macula and hopefully the
blurry vision, the eye needs to be repressurized to about 20. We tried
using gel (post surgery) and my IOP zoomed up to 70 in about 5 hours and
would not go down to an acceptable level until almost all of the gel was
removed.

So the gel works -- but all too well. :(

Quote:
Question: Does anyone else have this situation and use Ibopamine (Trazyl)
to increase the IOP?

Not me. I use eye drops to try and /lower/ my eye pressure.

Quote:
This drug is not available in the US but is available
in Europe, particularly in Italy. I was told it was available via the
Internet but cannot find a web site from which to order it.

I would strongly advise against ordering any drugs over the Internet,
especially drugs not approved by the FDA.

Quote:
After about 6
months my condition is considered permanent, so my window of opportunity is
closing.

You need to talk to a real professional in your field. If your current
ophthalmologist can't help you, look for a local hospital that has a
decent ophthalmology department. That would be your best bet, IMO, for
getting quality help.

It also occurs to me that you might find information on your condition
at Medline on the web. Just do a search on "Medline + vision" and see
what turns up.

The US National Eye Institute might be another good source of
information.

Good luck,

Funny, correcting garbage with more garbage. Get a life. The lens not
only has no blood supply, it also has no pain or other nerve connections.

To say the least. I suggest you remove all the cross posts if you reply

You need to study a bit about ocular anatomy and physiology. For
starters, the lens has NO BLOOD SUPPLY.

Visual migraine affects the lens of the left eye causing auras. The
blood vessels supplying the lens constrict suddenly and completely.
This starves the lens of necessary proteins it can only recieve from
the blood (hemoglobin included).
