I am working in uniformed services and that’s why I would like to have a laser vision correction surgery. I suffer from myopia (-3) and slight astigmatism. Ophthalmologist, after a preliminary examination, said that I would qualify for Laser Vision Correction surgery but only after pachymetry (which he wasn’t able to perform). However I am worried because my pupils are not situated centrally – they are shifted medially and upward. Additionally, I am an athlete and I actively engage in various strenuous exercises. Is that a contraindication for the surgery?
How long after the surgery would I have to wait to return to regular physical activity? I have heard that it is possible to completely lose visual acuity and to have double vision after the surgery, how often does it happen? What does it result from? Thanks in advance.

Taking your errors into consideration it indeed looks like you are a fine candidate for a Laser Vision Correction surgery. Just as your doctor said, the thickness of your cornea (along with few other parameters) has to be checked to fully qualify you for a surgery. It is not uncommon for the pupils to be decentred but to determine whether the misalignment of your pupils will be an obstacle during the surgery I would have to examine them. Usually the cornea heals for about 10 days and after that you can return to physical activities. However I would strongly recommend you to avoid strenuous exercises for at least a month after the surgery. The mentioned complications are extremely rare (according to multiple studies the probability of all of complications is lower than 0.5%). It is hard to tell what causes them as the main purpose of the qualification process is to rule out any risk of them occurring. Despite that, after Laser Vision Correction, just after as any other surgery, some complications may occur.
