Hey.............I just remembered one thing for his eyes............In Surah Qahf (50) Verse 22 is a cure for eye sight.

"Assuredly, you were heedless of this, therefore We have removed from you the covering, so today your sight is sharp."
After Farz, recite durood shareef, this verse starting from 'Fakashafna' seven (7) times and the durood again. Next, blow on your hands and move them over his eyes. InshAllah, recovery will be quicker.
Another thing would be to do the Surah Rahman thing and to wash his eyes with the water.
