salamu 'alaykum my beloved brother or sister.
One thing you can do is to ask Allah to heal your eyes by invoking His name An-Nour (The Light).
The other thing to keep in mind is when your eyes itch Allah forgives you some of your sins, insha'Allah. And then if you say "inna lillah wa inna ilayhi raji'un" Allah will reward you for your patience and you will gain His pleasure. Now you tell me, is there anything better than gaining His pleasure?
I can relate to your situation. I have had vision problems and pain in my eyes for many years (and I still have them). But al hamdu lillah, I can see with my eyes.
Don't let this test of your go away without gaining Allah's pleasure. Thank Him for the sight He has given you, tell Him you appreciate it, and ask Him to show mercy to you for being patient.
May Allah cure you, and may Allah grant you His pleasure. Ameen ya rabb al-'alamin.
