Hello, I was adviced for femto Lasik as I am having enough corneal thickness for high myopia. In my final refraction checkup they said there is an increase of -0.5 Sph in right eye and and -0.5 Sph decrease in left eye . But since this is a small change they told not to worry and its subjective .I have small ghosting in my right eye. I am just scared that this will overcorrect or undercorrect the vision (especially night). Are they going to feed the exact refractive error in Lasik or will they again measure the refraction before surgery ? Thanks
