Dr. Patricia Beatriz Sierra, MD

I had a very unpleasant experience with Patricia Sierra MD. If I could give her zero stars I would. Because of her multiple misdiagnoses she caused me several months of agony and permanent pain in my right eye. In 2025, Patricia Sierra recommended I have light-adjustable lens cataract surgery, for which I paid her $10,000 (ten thousand dollars). The pain after the first operation was unbelievable. It was off the scale and one of the worst pains of my life. When I reported it to her she said it was “dry eye” and would go away. Of course, it didn’t go away and it got worse. I repeatedly told her how severe the pain was and that it didn't feel like dry eye. She insisted that's all it was. This went on for a few weeks during which I suffered greatly. Eventually, I could tolerate the pain no longer and went to see my regular eye doctor. He said that I had inflammation in the eye. He prescribed anti-inflammatory meds which reduced the pain significantly. Sadly, the inflammation was severe… and had gone on for so long that my eye was permanently damaged. So, there is still pain there a year later. Patricia Sierra also was mistaken about the outcome of the surgery. She told me I would have 20/20 vision after the surgery and that I would not need to wear glasses. Sadly, my vision is now only 20/25 in one eye and 20/30 in the other and yes, I have to wear glasses. When I wrote to Patricia Sierra about all this, she was not very sympathetic but did offer me a small, partial refund. All I can do is share my experience with other people so they can make an informed decision.
