LASIK permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A mechanical microkeratome (a blade device) or a laser keratome (femtosecond laser) is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the corneal stroma, the middle section of the cornea. Pulses from a computer-controlled laser (excimer laser) vaporize a portion of the stroma and the flap is replaced.[2]
Performing the laser ablation in the deeper corneal stroma provides for more rapid visual recovery and less pain than the earlier technique, photorefractive keratectomy.
[• Undercorrections. If the laser removes too little tissue from your eye, you won’t get the clearer vision results you were hoping for. Undercorrections are more common for people who are nearsighted. You may need another LASIK procedure within a year to remove more tissue.
(Linked texts cover additional risks, just highlighting the ones proving LASIK works by permanently damaging tissue)
versus ICL:
[After dilating and numbing your eyes, your surgeon will make a very small incision at the base of your cornea. They’ll fold and insert the implantable lens into the cut and then adjust it behind your iris and in front of your lens. You probably won’t need stitches because the incision is so small and will heal on its own.
Sorry, y’all have been bamboozled then, and you’re the one spreading qanon level misinformation. The only real thing you’ve said is that ICL is more expensive, which is true. Which calls into question the integrity of the rest of your anecdotal claims as well.
LASIK:
"An excimer laser precisely reshapes the stromal layer of the cornea, removing microscopic amounts of tissue to correct refractive errors. "

• If you needed to have the surgery reversed, you could. There’s no structural damage to your eye. ](https://my.clevelandclinic.org/health/treatments/25050-implantable-collamer-lens-icl-surgery) And unlike LASIK:
• You’re at less risk for dry eye.
• You may have really good night vision.

Your own source material betrays you.
The cornea is not YOUR INNER EYE
Ok, my mistake, I made one error, about which part LASIK permanently burns off and damages.
My bad.
The main point still stands tho.
