I had a PRK surgery in my left eye, followed by an enhancement, which did not prove efficient and a LASIK surgery in my right eye which proved very frightening, due to unexpected night problems.
I have haloes in both eyes but the right eye, at night, seems more like -7.0 diopter then anything else.
My pupils are large enough to be the cause of that and the right one is larger, though i dont know their actual size.
My corneas were diagnosed as suffering from abrasions. As my two doctors have described: the inner side of the cornea is curved diffrently, and this, along with large pupils, is the cause of my halos. The abrasions are more intense on the right eye.

Yet i'm not convinced:
1) Abrasions are, as far as i know, scratches. That would seem to me rather like a characteristic of the outer side of the cornea, and would indicate a complication rather then a natural defect.
2) Splitting my vision in two, or hiding a different eye every time, i have noticed the horizon (take the sea for instance) is straight in one eye and tilts in the the other, or more like as if i was looking from a different angel. As odd as it may seem, I'm unable to tell which eye is straight, though i suspect the left is.
I did not consult with my doctors about this strange thing yet, but i believe that this is how those "abrasions" take effect on my vision.

Has anyone ever heard of such a case or description?
Could it be the cause of irreguler astigmatism?
What is an abrasion really, in the world of ophthalmic surgery?
Is Wavefront technology known to be any good for these problems? my doctors seem to think so.

Thank you, Guy.

It sounds like you need a second opinion. Abrasions can occur at the time of surgery, but should completely heal after a few days to weeks to at the latest months.
The visual effects you are describing can be anything, from residual astigmatism to irregular astigmatism.

A second opinion would probably be best - as things like wavefront are not yet perfected.

Best of luck
