I had it done 5 years ago and as a result lost vision in one eye for 2 years.
I got a disease called “Thygeson Superficial Punctate Keratitis” and as a result the cuts they made in my eye didn’t heal.
Had several operations to basically scrape the surface off my eye off with what appeared to just be sandpaper (ARARAGARGAGARGASRH!) in the hope each time that it would grow back normally. It didn’t.
Took steroids and a bazillion other drugs for years in an attempt to resolve it. Also had to clean my eye every hour with baby shampoo and hot pads which relieved the pain and irritation somewhat.
Oh and I couldn’t look at light as it hurt, so had to wear shades at all times. Which looks really silly when you’re a programmer 🙁
Eventually the disease cleared up and my vision returned.
I now have my eyesight back to 100%, but only if I’m wearing a bandage contact lens which smooths the scarred surface of my eye.
The disease still flares up if I’ve got a cold or something, but fingers crossed it’s gone for good.
TLDR: Worst mistake of my life, you’ll probably be fine, but why gamble with your eyes?
