I would assume they would request a remedial.
It may be you will not be allowed to contract until the remedial is done. That becomes a question of how long it cold take. If it takes months to get through the process, you are not going to get your tuition paid, books an stipend until you contract.
Additionally, I would ask the cadre if they back pay it if you need to get a remedial. They may say, NO, we only pay from the moment you contract. What if they contract you in Nov.? Will they pay for fall semester tuition or not?
There are a lot of IFs in my post, but that is what I would be looking at.
When they waive, they accept all of your pre-existing conditions. As USNA stated, I would wait until AD.
Our DS wanted to get PRK done believing he needed it to get UPT. He was on the cusp, so it would have been elective. We told him flat out, you don't risk a surgery, any surgery unless you have to have the surgery. In the end his eyes were fine according to the AF. He has a pilot slot. Later on if he needs it, the AF will pay for it.
I don't know if you are having a nose job for looks, or because it is causing minor medical issues, but JMPO. I wouldn't risk it at all. Than again, I tend to lean on the conservative side when it comes to medical issues.
