The only reason to remove an iris is to eradicate iris cancer. I have come across couple of patients in my clinic asking to change the colour of the eye by removing the iris. This is completely wrong and I am not sure where the idea of iris removal came from....
Yes, this is too high to do lasik. It would thin your cornea too much. However there are other surgical alternatives to high myopia that you could explore with a refractive surgeon.
