Yes, I have been dealing with dry eyes for 40 years! I use Allergan's Refresh Celluvisc preservative free eye drops (artificial tears) many times during the day and night time ointment at night. Years ago, I tried Restasis which I discontinued because of severe stinging and burning. Just had an appointment with my over 80 now retiring ophthalmologist who recommended trying Xiidra (lifitegrast ophthalmic solution) which recently became available in Canada. Was just about to start a discussion group to get feedback on Xiidra.
