My experience has to be an exception rather than the norm, but maybe
not such a rare exception.  I had a vitrectomy with epiretinal
membrane peeling in January 2006. My vision in the affected eye went
from about 20/40 to better than 20/20 post-surgery.  Of course, I
developed a cataract, but that wasn't such a bad thing because I went
from being a high myope to having 20/20 uncorrected vision.  (I did a
lens exchange in the other eye.)  But there's been a major down side.
My affected eye teared continuously post-surgery, for which I was
prescribed a variety of dry eye remedies.  I also noticed that objects
viewed from my affected eye were larger than those viewed from my
other eye.  I told my retinal surgeon, my cataract surgeon and my
optometrist about this, but no one found it significant.  About 10-11
months post-vitrectomy, I also noticed that distant objects seemed to
be on the verge of doubling.  (And occasionally did double.)  I began
doing my own research into my symptoms (tearing, binocular vision
problems) and diagnosed myself with retinally-induced aniseikonia.
(Aniseikonia involves a disparity in image size between the eyes and
involves a number of possible symptoms.)  Apparently, the epiretinal
membrane had damaged my macula, compressing the retinal receptor
distribution.  The blur from the epiretinal membrane masked the
damage, and the peeling revealed the problem.  Since there are no eye
care providers in my area who treat aniseikonia, I've been forced to
coordinate my own treatment.  Ironically, most treatment methods
involve blurring the vision in the affected eye.  I probably would
have been much better off if I had not had the surgery, and I would
certainly have been spared a lot of anxiety.

If you do opt to remove your pucker with a vitrectomy, I would suggest
two things.  (1) Find the very best retinal specialist in your area.
(2) Use the new 25-gauge vitrectomy equipment (as opposed to the 20-
gauge equipment).  Recovery is reported to be much faster.

I can reassure you to have this procedure done. I am grateful to my
ophthalmologist to urge me to have it done. At the same time I
recommend that you try to find the best available eye surgeon, who has
much experience with this operation. I asked my surgeon how many times
he had performed it. He said he does it 440 times per year and in the
last 20 years had done it 6000 times. My ophthalmologist had
recommended this particular doctor ond did not think so well about
another hospital.
I was diagnosed macular pucker, epiretinal membrane, 8 years ago on my
right eye. 4 years later my left eye began to develop it also. I was
reluctant to have it operated because I am not fond of my eyeball
being pierced or stung or whatever horrible things one can imagine.
But blurred vision and straight lines turning curvy got worse, so I
followed the advice of my ophthalmologist to have it treated. The eye
clinic of the Lucerne (Switzerland) has an excellent reputation. I had
an interview with the performing doctor, and he was very confidence
inspiring. I would first have the right eye operated. The left eye
could follow 3 months later. The operation would last for about one
hour.
The operation consists mainly of removing the vitreous body and
removing the membrane causing the problem. I addressed the often
mentione problem of a cataract developing in the year after the
operation.  The doctor said they routinely do the cataract operation
preventively at the same go, so there would not be the need to have it
done later.
I had the operation 3 weeks ago. It was under local anesthesia. The
injection of the anesthetic beside or behind the eyeball was painless
as a short acting sedating agent was injected intravenously in the arm
beforehand. The whole operation was truly painless.  I was conscious
all the time, but did not understand much of the conversation above my
head. They spoke in a low voice and the doctor gave only short and
clear commands. My experience was not at all frightful.

For about half a day my vision on the right eye was only diffuse
light. After the vitrectomy the eyeball was filled partly with a
liquid, partly with air. The refraction of light by air gives a very
blurred image on the retina. After a day the air bubble had already
slightly shrunk and I could see normally in the uppermost field of
vision. The air bubble is of course on top, but as the lens inverts
the image, it looks as if it were on the bottom. The bubble shrunk
progressively. After three days the field of vision was sufficient for
driving. On day 10 the bubble had gone completely.
I stayed in hospital on the day before and on the day of the
operation, but could go home the day after. I had to return daily for
checks on the first few days.
A concern, which I had from searching the Internet, was that one would
have to stay and sleep head down for up to 2 weeks. Operation
techniques seem to have improved tremendously, I did not receive any
such instruction. I should however not sleep on the back, but on the
side. For as long as the air bubble was there I should not go to
altitudes higher than 1200 m (about 4000 feet). Which means I should
also not travel by air.
How is the success? The recovery of the retina needs several months.
At this time the improvement is clear, but not great. There is a clear
improvement of near-vision, reading in books and on computer screens.
I can even read font 10 texts again on the computer screen without
glasses, though not comfortly. Far vision and seeing distorted
straight lines seems to improve only slowly, but I was told that the
retina needs  time to rearrange itself. I will need new glasses after
full recovery.
My conclusion at this time: I am very happy. Anxiety before the
operation was unfounded. I had the impression I was in caring and
competent hands at the Lucerne hospital. I guess they use the most up
to date equipment and are very experienced. I look forward for a great
hiking season in the Swiss Alps without being afraid of stumbling
because of bad vision.
I wish you good luck. Be confident!
