I have suffered with Dry Eye for years. I was unable to tolerate Xiidra (have tried it several times throughout the years and it burns my eyes) and Restasis never did a thing to help me. However, about 6 months ago, my Ophthalmologist gave me a prescription for a Generic eyedrop for Restasis, and it is amazing. These drops come in single use vials of Cyclosporine Opthalmic Emulsion, 0.5% manufactured by Allergan Sales, LLC. I put one drop in each eye morning and nighttime, and I am amazed at how much relief these drops have given me.
