Yes, you can give individual permissions for every document in a list. To do this, you have to break up role inheritance with the BreakRoleInheritance() method on the SPListItem.

You can then set new individual permission for this item. Have a look at this blog post it describes how to change permissions via code.

So remove the permissions for an item and re-add them only for the user how should be able to see or edit them. Using different RoleDefinitions you can decide what an user is able to do with the document. Only see it or also be able to edit it.
