PRK Waiver Denied- Post Commissioning Touchup Possible?

[jbweldon04]

A prescription for a refractive error is 3 parts. You have your sphere power which is first, then your cylinder power, and finally your Axis. SO:
-1.00-0.50X180is a prescription.
You have -1.00 spherical power, a cylindrical power of -0.50 and this cylinder power is corrected at axis 180.

The spherical portion of the prescription corrects for whether you have a short or long eyeball. If it's short then you have hyperopia and that's correct with + spherical powers.
If you eyeball is long then you have - power.

In the United States we use - cylinder values, and cylinder corrects for misshapen corneas that are shaped like footballs instead of perfects circles. The axis is just where on the eye you correct for the cylinder value.

In regards to a changing prescription after surgery, it's not uncommon for that to happen. Your eye is still in it's healing process. I work with a guy who got PRK, was 20/20 in both eyes after one month, and now is 20/30 in his left eye only one year afterwards. The surgery is intended to reduce your dependency on glasses, not exactly to rid yourself of them.

Hope this clears up some confusion.

I should be all set. Went to the doctor today and I was measured at the same refractive error and vision as my last visit. If they don't consider that stable, I don't know what is. Guess I will get final word from CNRC next week on whether or not I am PQ or NPQ.

That took a lot longer than expected. For anyone that was following this thread in a similar situation, I got the word today that my PRK waiver was approved

Just a follow up on this. I was pretty much ready to go ground after TBS because I was dq'd for anything aviation. I commissioned and asked about getting a touch-up during my 11 month wait for TBS. After getting a bunch of "No's" from various staff in my ROTC unit, I was finally given the go-ahead to get the damn PRK touch-up and reapply for the waiver and the flight contract. I may be joining you boys in Floribama after all.
