I welcome you to our website, and hopefully, at some point, to our office located in Encino, California. The purpose of this website is to give potential patients some basic information about my office and myself, David Paikal, MD. My practice specializes in comprehensive ophthalmology, where I favor conservative approaches, striving to be true to the bioethical tenet of “first do no harm.”
My staff and I will do everything possible to take the best care of you. The reason we can do so is because we love what we do: helping people to see better. Sometimes, that means admitting that we don’t have all the answers and referring you elsewhere. No one physician knows it all, and my staff and I are fortunate to have strong relationships with various sub-specialists, including academicians at universities, should the need arise.
In the great city of Los Angeles, we are blessed to have many world-class ophthalmologists, and therefore, your eyes will more than likely be in the best of hands with the majority of eye-care providers. Ultimately, your decision as a patient on whom to choose will really rest on who you feel most comfortable with, and where you can achieve the kind of patient-doctor relationship you are looking for.
My educational background is attached for those of you who are interested. I wish you health and happiness.
Sincerely,
David Paikal, M.D. Diplomate American Board of Ophthalmology Assistant Clinical Professor, UCLA Stein Eye Institute

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.
