How long should I wait until the nose flies after the last different service?

Hello everyone! I'm a Mongolian here under the name Od. I'm planning to have a cataract surgery at one of the hospitals in Seoul later this month. But then I have to fly back home. Does anyone know how long the blurred vision (blue tail, hazel, etc.) lasts after the injection replacement service?

I think it will be a few days or a week, but has anyone been able to tell me how long it will actually last? What kind of treatment do you think I should take before flying? Also, does the blurred vision generally fluctuate? Sometimes people say that they look good, not sharp.

If you've had this done before, please feel free to share! I'd just like to hear from people with good knowledge.
