Treatment for diabetic retinopathy with laser: how long is recovery time?

Not long: Normally, within a few minutes you are comfortable and your eyesight has returned to baseline. You may have a headache for a few minutes to hours.

Depends: If you have blood in your eye, that will take many weeks or possibly months to clear even with laser treatment. As for the laser itself, usually the blurriness doesn't go away for a few hours because you would have been put on dilating eye drops.
