You can hurt your “new” eye by making it try to work with its partner which needs to focus to see when your operated eye needs to rest to heal. Each situation is unique and you should ask about the best strategy to integrate your new eye with its partner.
Also, remember that most treatments DRY UP the MUCOUS MEMBRANES, making infections caused by resident germs even more opportunistic because they can only grow easily in low oxygen environments. Normal SALINE is 99.1% WATER, and water is 80% oxygen! Oxygen-rich wetting agents are therefore better than sticky or oily ones for most purposes.
Your eye physician should guide you to specific treatments after a careful exam, as many "red, itchy eyes" are not just allergies.
