Dr. John Berdahl – Ophthalmologist Surgeon

Meet Dr. John Berdahl

Practicing in Sioux Falls, SD is our board-certified ophthalmologist, John Berdahl, MD. He is widely regarded as one of the leading international cataract surgeons. He is one of the very few surgeons in the United States who is also fellowship trained in cornea, glaucoma, and refractive surgery. Dr. Berdahl has already performed more than 35,000 eye surgeries around the globe. His published work has primarily focused on the fundamental causes of Glaucoma, Minimally Invasive Glaucoma Surgery, and Astigmatism Management, during and after cataract surgery.

He has been involved in numerous FDA monitored clinical trials on some of the most exciting technologies in ophthalmology. He also founded Equinox, which is developing the first non-surgical, non-pharmacologic way to lower eye pressure for glaucoma treatment. He co-invented the MKO melt, which provides sedation during cataract surgery without the use of an IV. Additionally, he created astigmatismfix.com which helps thousands of surgeons per month fix residual astigmatism after cataract surgery. Finally, in an effort to improve access to care, he co-founded ExpertOpinion.MD which provides online opinions to patients from top doctors around the world.

Although Dr. Berdahl has many accomplishments, his primary driver is the trust that people place in him, particularly meeting his patients in their moments of vulnerability and putting their needs first. His commitment to the underserved is demonstrated by his leadership in EyeCare America, as well as in the Mission Vision program at Vance Thompson Vision, where he performs dozens of free surgeries every year. Dr. Berdahl also continues to serve the impoverished on mission trips world-wide.

"Dr. Berdahl did my LASIK over two years ago and it has been one of the best choices I have ever made. My vision is still awesome! I felt well informed and relaxed about the entire procedure. The entire team was outstanding and I could not have asked for a better outcome. Highly recommend!"

"I have a eye disease called keratoconus. As my keratoconus got worse, many eye doctors told me I would never be able to see very well again, until I meet Dr. Berdahl. He was able to get my vision all the way back to 20/20, something I expected would never happen again. He is now the only Dr. with whom I will trust my eyes."

"Dr. Berdahl recently performed my LASIK surgery and he was awesome! He answered all of my questions during the initial consult and was comforting during the surgery. I was nervous about how I would react during the surgery but Dr. Berdahl was encouraging through the whole procedure. I can honestly say that I had a fun time before, during and after surgery! My vision is fantastic and was seeing 20/15 after one week. I'm so excited that I don't have to worry about glasses anymore when taking photos. I recommend Dr. Berdahl and team to anyone who is considering LASIK surgery."
