Hypertonic Saline Responders
Hypertonic Saline Non-responders
Subjects who qualify as hypertonic saline responders will be instructed to instill 1-2 drops of preservative-free Refresh Optive Advanced Lubricant Eye Drops, which are available over the counter, into each eye twice a day for 28 days.
Subjects who qualify as hypertonic saline non-responders will be dispensed the same instructions and treatment as the Hypertonic Saline Responders. They will be instructed to instill 1-2 drops of preservative-free Refresh Optive Advanced Lubricant Eye Drops, which are available over the counter, into each eye twice a day for 28 days.
