Head and Jaw ache

Hello, I got refractive correction surgery 6 weeks ago. From past 2-3 days I am facing headache(in the back head) and pain in the jaw area. I am wondering is it anything to do with the surgery or is it because of weather as it is getting too cold here in the area that I stay.

Cataract surgury& astigmatism correction

Before surgury cylendrical power was -2.0 and sph power was -3.0 but after surgury sph is +0.50 and Cyl power is -0.25 from auto refraction, but vision is 6/18. Here where it went wrong, why outcome is not good and why sph and cyl power is shown negligible in auto refraction though vision is 6/18.? Hence i request you to pls address my concerns.

Femto Lasik

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

Spectacles with scratches effect on RPow

Hello doctor, I just want to ask if it's better to use 1. Specs with too many fine scratches and stains if they're of the correct refractive power OR 2. Specs with a difference of 0.25 refractive power in one eye and 1-2 prominent scratches. As a student preparing for a competitive exam I do not want to spend time selecting and buying a new frame for the next 5 months  unless it will significantly affect my refractive power since it is as high as - 5 and - 4.75 or be a potential cause of headaches. Thank you

Reg. Tilted Optic Disc

I had refractive error of -5.5 D and I had undergone LASIK 2 years ago and my now my vision is 20/20. In one of my recent checkups in my fundus exam reports, it was given "retina is on and dilated fundus is within normal limits". But my right optic disc is given as "normal and tilted" and all others were given normal in reports. Does this mean pathological myopia?
