What surgery should I consider for my left eye?

Hello all,

I have been using spectacles since the age of 10. At around 14-15, I got to know I have amblyopia (lazy eye) in my left eye. Doctors suggested eye patching for six months, but there was no improvement, so they suggested to stop it. They said that eye patching works best before the age of 12.

My eyesight has stabilized over the years (currently, I'm 22). When I was around 19 (in 2023), my eyesight was -5.5D in the right eye and -8.0D in the left, but during my last visit (after 2 years, in 2025), it increased to -6.5D and -9.5D. Also, I have astigmatism in both my eyes. Even with -9.5D in my left eye, I only have 20/80$vision (with specs) due to amblyopia.Currently, I have -6.5D (sph) and -2.0D (cyl) in my right eye, and -9.5D (sph) and -1.75D (cyl) in my left eye. I mainly use my right eye vision instead of both eyes daily due to amblyopia.

During my last visit, I asked doctors for surgery options, and they conducted some tests. My corneal thickness is 520um in both eyes. They suggested PRK for the right eye and an ICL toric lens for the left eye since PRK isn't possible. After surgery, 20/20 vision is possible in the right eye, but in the left eye, it will be 20/80. Daily, I mostly don't use vision from my left eye, it only appears when my right eye vision is blocked, and it is blurry.

I understand that they remove some of the cornea in PRK surgery and maintain a safe amount of thickness. So, should I get PRK in the left eye and try to reduce the prescription as much as possible and live with it. I am thinking I will not use my left eye in day-to-day basis, and with 20/80 vision, I will be able to see things properly after surgery also. Is it better to go with that or just get ICL in the left eye? If you have any other suggestions, I will discuss with my doctor or I should not go with any procedures in my right eye also due to amblyopia in left eye. What are risks of PRK in only good eye.

Thanks for your suggestions.
