An Irish Terrier was ecstatic to be reunited with his family after surgery to restore his sight.

Duffy was diagnosed with diabetes last year after suffering from several health problems.

His family struggled to control his blood-sugar levels, and Duffy went blind.

After the diabetes was under control, Duffy underwent surgery to restore his sight.

A video posted to YouTube by Benjamin May caught Duffy's amazing reunion with his family on camera.
