i agree with iflysoon.....i just want to add that if u go for lasik surgery....dat will make u permanently unfit.
If you dont know facts is best to shut up.
I did LASIK , had -8 and -9 diopters before and now have 20/20 vision both eyes. I have a valid FAA , Canadian and an Indian Class 1 medical which was renewed for the 2nd time this Feb.
LASIK IS allowed by DGCA and my renewal medical just took half the day incl waiting times and I got my medical issued.
