Hello there,

Sorry to say but you won't be able to clarify the medical test for NDA even of your have done LASIK surgery. The main reason is you can apply for NDA between the age of 15.5 years to 18.5 years and as per US-FDA the minimum Age required for getting LASIK surgery is 18 years.

But don't worry you can give CDS exam. The Indian Defence services allow LASIK surgery (only if LASIK has been done after the age of 20 years).(but there are some conditions)

Some conditions are LASIK surgery should have been done after the age of 20, should get it done at least 6months before the medical exam, residual corneal thick should not be less then 450 microns, the axial length should also be within permissible limits.

So you will not be eligible for NDA but you will be eligible for Indian Defence.

Good luck!!
