I am myopic, with ~ -5.00 diopters left eye, ~ -4.50 diopters right eye.

One year ago I developed a strange problem on my left eye:

I see a spherical distortion with my left eye as follows:

Looking at the central red dot of the right grid, my right eye perceives the
right grid, as it is.
My left eye however, perceives the right grid, as it appears on the left
side.

The drawing is slightly exaggerated but I do see a bowed vertical line, so
the distortion appears to be against the horizontal axis only.

After becoming aware of this, I went to my ophthalmologist and had a full
eye exam. I had both an external eye test and a retina/eye pressure test
with anesthetic.

He found no problems with my lens, retina or eye pressure. (all came up
normal).

He said that this is a common condition caused by stress at around the age
of 40 (my age), with some cones and rods becoming slightly "bent" on certain
areas of the retina, similar to how the wool threads of a carpet can be
"bent" after being stepped upon. I don't remember what he called the
condition.

He did suggest that I have a Fluoroangiogram, which I did not have, however.

The distortion isn't very obvious when I am looking at wide images, but it
becomes more pronounced when I read or look at details.

It's been one year and some months since I developed it. Does this condition
ever go away? Is it dangerous? Can it be corrected using laser surgery?

Thanks much in advance,
