I had LASIK surgery done a few years ago and hold a Class 1 medical.
The LASIK results were fantastic and I haven't need glasses since. Great for driving and sports are well as flying. The only downside is that if takes 10 minutes in the morning before I can focus properly to read my phone.
I used Dr Alpins in Cheltenham because he came recommended and is a CASA approved Ophthalmologist.
Alpins charges twice as much as others, but is very good and has a flawless reputation.
You can't fly for a month after the LASIK surgery, after which you have some eye tests and the results are sent to CASA.
CASA messed me around for another month or so, but a couple of polite phone calls to CASA in Canberra resolved this and a new medical appeared in the mail in a couple of days.
The only other pain is that my Class 1 renewal sometimes requires another Ophthalmologist report in addition to the exercising ECG crap.
