As someone who never had any issues with my eyes, is worse night vision and/or increased dryness something that is considered "life-altering complications"?
Tears are a crucial part of the vision. With less tears, the eye has worse vision. So one can end in a paradoxical situation where they have a better vision in theory (and tests!), but in practice, they may see considerably worse. And there's nothing one can do - eye drops only last a short amount of time.
I had considerable eye dryness that improved over several (5+) years, which is almost entirely recovered. A couple of years ago I've tried contacts and they wouldn't hold (it wasn't the case pre-op).
The (licensed) doctor was a liar (about the risks), and they actually didn't care about me post-op.
I couldn't go outside for months. I'd wear double sunglasses and a hat. I'd just cover myself completely. I couldn't open my eyes to see, it was blindly bright. I couldn't use an oven, the hot air instantly and painfully burned the moment I'd open the over door. Etc.
It's the second worse thing of my life
People seem to google "lasik best prices" then wonder why their experience sucks?
Don't go for the first google links when researching something, avoid sensationalistic BS
But to your point: I will assume the HN who posted here was smart, and that the procedure was performed by a licensed professional within a standard risk profile, using equipment that was functioning as expected.
> within a standard risk profile
Well, not following post-op guidelines takes it out of the risk profile, still, it is good to have a second opinion and understanding the risks for your case
> laser used had a smaller diameter than my lenses
Given that it was 20 yrs ago it is possible that this was an effect that was not well known and it is better controlled today.
It is very possible that this result would have been better with modern equipment and techniques (especially if this was not bladeless Lasik) https://pubmed.ncbi.nlm.nih.gov/31353955/
This was known at the time. If you think about it, it's an obvious effect if you can't correct all of the surface that will admit light in. I had a great outcome with my eye surgery from around that time, with my vision needing no correction for 20 years now. However I distinctly recall the doctor saying that if some features were a bit wider (iirc iris), then his equipment wouldn't be viable for me. I feel strongly that the poster who had this situation had an unethical doctor.
