Hello, I'm young and in my twenties. I've long had puffy under eye circles as it runs in my family. after consulting with three surgeons about it they all advised me that my case was not bad and before going to surgery they'd suggest doing a minor injection into the tear troughs. Last night a surgeon did the job. If there was a complication ie.going blind etc how soon would I notice? What symptoms? My eyes just both feel heavy like a tired feeling so far..nothing bad, but just different.
