I have been unable to drive following four treatment appointments due to eye irritation. It was even worse following my last appointment, and I mentioned this today. She thought it might be that the betadine wasn't thoroughly rinsed from my eye, so she gave me a double rinse today. This made a huge difference. I look forward to driving home from my next appointment. I’ll still have my husband ride with me, but I think this will work out fine. The time after that he likely wont need to come.
