I wish you luck with the surgery. Knees, like eyes, are delicate things but as your recebt hernia surgery went well, I trust this one will too.

My post surgery regrets stem from one single, avoidable, issue. My health insurance provider covers basic lenses and the procedure. These lenses don't filter well the blue and the UV spectre of the natural light thus, after insertion, rendering everything bluish and expose the retina to more UV light which later can cause retinal damages. Anyway, neither my ophthalmologist nor the doctors in the eye clinic informed me that there are other types of lenses, e.g., those that do filter the bluish and UV spectre. Their disadvantage is that they are not covered by health insurance, so that I would have had to pay extra for them. And as the doctors later told me that, yes, my cheap lenses make the world look like under LED light, I am angry that they didn't tell me prior to the procedure. If they had decribed it to me that way, I could have anticpated the visual impression and rush to ask my family to pool some money.

How the fuck can you act properly when you don't know what you don't know and the specialists don't care telling you?
