Hi Moi
Absolutely not. Asymmetry in the optic nerves are due to many reasons, most of them benign.
These include normal anatomical variations, differences in the degree of your myopia / refractive error or other ocular / retinal pathology that is unrelated to the success of LASIK.
You should have a frank and detailed discussion with your LASIK surgeon about the cause of this asymmetry in appearance of your optic nerve.
Best of luck with your procedure!
