I have been practicing in Reseda since 1981 and I have seen so many changes. But what hasn't changed, eyeballs! Although I enjoy using the latest technology to help view, diagnosis, and treat my patient's eyeballs, they are still just my patient's eyeballs. I love educating my patients as much as I love educating myself. I believe it is important to understand what is going on with your eyes, how it happened or got to this point and what our part is. I believe if we are educated then we will be better equipped to make better decisions.
