Is there any possibility to restore vision that was lost due to stroke?

No. Transient ministrokes sometimes can have vision or visual field return if the retinal or brain area of shortage of circulation is temporary and the nerves can survive. Cases of strokes over several hours to days old are unlikely to recover vision.
The duration, type of stroke, bleeding vs. Clotting vs source for example from the heart, from the lungs, from the brain or eye, or systemic circulation or systemic disease may also play into the ultimate visual outcome from the stroke.
