I had my transPRK surgery this Monday at Laservue and everything went really well my prescription is down to around -3.5 and -4 from -11 and I am quite happy with the results so far.burnt69 wrote: ↑
Not sure about Canada DND, but I know the US DoD has requirements of pre-treatment refraction which would be unfortunately violated even if treatment was successful for someone -11. The substantially elevated risk of retinal detachment in high myopia does not go away merely because of corneal refractive surgery.
As to your comment about pre-treatment refraction limit it is really concerning. I couldn't find anything for CAF except some memos for pilots and aircrews which sets a limit for pre-op prescription. If you can find anything else I would really appreciate it.
