service was quick, exam was a bit stressful and longer then I anticipated, there were computer errors and glitches. Dr, did a great job he did a major improvement in my vision. I did discover a billing error they overcharged my credit card. I was told amount after discounts and Insurance, but when I checked my credit card statement a few days later to pay bill I was charged full amount. This means a trip to store for me to make them straighten billing error or embezzlement which ever it was. So receipt says one amount credit card statement another. HMMMM
