ANISETROPIA QUERY. After lasik?

I am 25, I often notice outward deviation in my right eye when I do any close work for a long duration. Otherwise my eye alignment remains normal. When I use my glasses, my right eye turns outward slightly (about 15°), but when I remove my glasses, that eye immediately comes back to normal position. My doctor prescribed me convergence exercises because she said that strabismus surgery is not advised in such inconsistent duration of amblyopia. I have a large difference in refractive power of both eyes. Right eye -4 along with -2.75 cyl and left eye -6 along with -2.5 cyl. I was operated for amblyopia when I was 6 years old. I will undergo for LASIK in a few days. Doctor said this may be a case of refractive amblyopia or anisometropia. What is this term? Am I  suffering from anisometropia? Will it be corrected after LASIK? As both eyes will be plano after LASIK. Please elaborate.
