I went to a PRK/LASIK consultation today and was told my astigmatism is too high (3.75 diopters) to have either corrective surgery done. I'm trying to be a pilot in the USMC. They suggested refractive lens exchange as an option but I'm not sure if I can get a waiver. I asked my recruiter who said he would look into it. Has anyone been through a similar situation and give some advice?
