This would be a 10-star rating if those existed! Dr. Vandenburg was a God send! He diagnosed my dry eye syndrome that was affecting everything from my vision to my energy. My eye tiredness due to dry eyes resulted in a lack of energy - I didn't want to even open them in the morning because it felt like a layer of cornea was being peeled off every day. Eye drops burned, blurred, and almost made them worse. Dr. Vandenburg prescribed "serum tears." I had never heard of them, but they have been around since the 70's. Made from the patient's own centrifuged-out blood serum added to saline, there is no chance of allergy, irritation, or rejection. HUGE DIFFERENCE IN THE FIRST MONTH!! I'm in my second month and my vision has already improved; my eyes feel wonderful! I can open them in the morning without pain or having to blink 50 times. I can't thank the doctor, the person who took my blood and made the tears, and the whole staff who go out of their way to be accommodating! They are the best!
