Lasik is a great example, thank you!

Though I wouldn’t put glasses in the same category because it’s not a cure, it’s a medical device to correct the medical issue and it requires you to use the device for the rest of your life, if you stop using the device your symptoms immediately return, that’s not a cure. Glasses are the equivalent of insulin for diabetes. It’s treatment, not cure, without it, the disease takes full effect, but with it, yes you will be functionally cured as long as you have your glasses/insulin available, but even when functionally cured, you will always be a person with low vision/diabetes and always need ongoing treatment…until there’s a “cure”.

If my poor vision was cured by getting glasses I wouldn’t be squinting while I’m typing this in size 18 font (my glasses are in the other room and I’m too lazy to get them), and I wouldn’t suddenly be completely disabled by my lack of vision when it rains (glasses need to come with windscreen wipers! I can’t see shit in the rain)
