Would sound stupid, but did you try doing something like yoga and herbal stuff?
My mom at 40 had a test and it came out to be -2.5 in both the eyes.
Fast forward to 2-3 years, it was -0.5 in both the eyes, I believe.
If I remember correctly, 2 years back a doctor told her she has a possibility of Cataract in her left eye.
and in 6 months or so, the doctor was actually surprised to find nothing and just improvement :O
She did Yoga and used to regularly put drops of Drishti (means vision in hindi and is available in India only). It's a product with mixed reviews, people said they've had infection due to, while my mother's eyes are pretty good rn.
I myself am sketchy about the product, it's painful as fuck (you would scream after putting only 1 small drop of it)
Recently a friend of mine(15-16) had an improvement after using Dhristi, not with the power of eyes but; improvement with being able to watch digital screens and feel no pain at all.
Anyway, I don't want to sound like a promoter of that product, just wanted to put in a perspective.
PS : Drishti costs like $1 lol.
Now coming to your original post, LASIK. Yes, a cousin and a family friend got it done nearly around a decade back.
My cousin would definitely recommend it while the uncle (family friend) had to undergo 3-4 surgeries afterwards and didn't see any major improvement in his eyesight.
I believe the LASIK tech has become better in last 3-4 years (at least it did in India)
