Quite surprised you were even considered a candidate for LASIK with 20-900 vision!
There was a time (early 1980s)when I was told my nearsightedness was so bad I'd have to wear hard contacts all my life and could never upgrade to softs . They said the curvature of my corneas was such that the lenses would bend to fit and distort my vision. But I switched from hards to rigid gas perms in the early 1990s and then to softs in the late 1990s, and none of the doctors involved seemed to think there was any reason not to.
Going from 20/925 (split the difference) to 20/15 in a matter of minutes...There are just no words for what a difference that made in my life. Best $3000 I ever spent!
My ophth surgeon said, “The worse the vision, the happier the customer with the results.”
I was wearing contacts AND glasses at the same time.
