I am a sufferer of dry eyes for many years and thought I’d give them a try. Dr. Fung did so many different tests that I never seen before to evaluate my tears. Never knew dry eyes can be so complex. He was very thorough and knowledgeable. Told me I had some gland issue and recommended a lid scrub treatment. What did I have to lose? so I booked another appointment where he used this device to scrub my eyelashes. It’s been a week now and so far my eyes do feel less dry but he’ll let me know how my eyes are at my next follow up an appointment.
