If a person has greater than 2 diopters of difference between their
eyes, the images will be focused with glasses BUT one image will be
considerably larger than the other and the brain is not capable of
reconsiling such a difference. This makes people with such an Rx
intolerant of glasses.. and they should go for contacts or something
else.

Very early in the widespread use of CK, patients were reporting
similar problems very often. In some cases, the surgeons who had
limited practical experience with CK would rush to retreat. In
general, it was found much better to leave the eye alone for about two
months.

It appears common for vision to immediately improve, go downhill with
ghosting and poor night vision hitting bottom at about a month postop,
then start improving with most if not all of the visual aberrations
resolving without treatment at about two months postop. Apparently
the reaction of the cornea to the radio waves is initially immediate,
but then takes some time to settle down.

Additionally, you are going to be adjusting to monovision. That is
another whole set of challenges.

My suggestion is to not do retreatment for refractive purposes until
at least two months postop. Give your cornea time to settle and your
brain time to adapt.

I am not a doctor.

I'm not sure what you are doing with the eyelid. You are probably exerting
some pressure on the globe, causing the cornea curvature to change to
create more astigmatism in such a way the the problem is neutralized. This
could indicate that more treatment will resolve the problem, depending on
how skilled your surgeon is. OTOH, you might be pushing the eyelid up to
form a narrow aperture, thereby blocking some of the peripipheral rays.

To induce monovision. My eyes have never worked together. I was born that way.
I was fine with making my left eye for close-up and leaving my right eye for
distance.

Is the fact that I can see close-up perfect if I lightly touch the bottom eye
lid indicate I am almost there? Would "more spots" do the trick?

CK, like any refractive surgery procedure, can result in a slight warpage
of the cornea called astigmatism, and this asymmetrical shape can produce
symptoms like you are having. The results of CK tend to fade over time
because the collagen fibrils eventually relax to a degree. Perhaps they
are wanting to see if this occurs. Also, did you have the CK done to treat
presbyopia by inducing surgical monovision, or to treat hyperopia
(farsightedness)?

Last Monday I had CK done on my left eye. Now, for distance everything looks
like a ghost - kinda double. Lights at night are the worst. A red or green stop
light no longer looks round - it looks oval shaped!

For close up, it is almost there. In fact, if I place a very light finger tip
touch to my lower eye lid - I see perfect!

I call the Dr. and I am told that it takes time and that I may need another
spot or two. Problem is they tell me to wait a few more weeks to see how it
goes. I am not getting better. I fear I am in trouble. Am I? If so, what
should I do?
