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.

"Without doubt, my complete experience at Vance Thompson Vision has been above and beyond compare. Every single person with whom I had contact was totally awesome - from the moment I called requesting an appointment through my departure from day-after-surgery check up. Sarah, Steph, Stephanie, Aimee, Dr. Ibach, Dr. Berdahl, Gideon, Chris, Becky, Jeremy . . . and just everyone! What an amazingly gracious team you have on board. Thank you for all the smiles, delightful communications, for uplifting my spirits, and giving me hope. I loved the surgery serenade, Dr. Berdahl and Surgical Team.

"I fell that there is no place I would rather trust my eyes to than Dr. Berdahl & Dr. Schweitzer at VTV. I started coming there 4 years ago for Cataracts in both eyes & discovered I also had Glaucoma. Since then I’ve had Lasik both eyes, glaucoma medicine & followup by them when I came in every 3 days to get pressures down! PTK was a snap. I have to admit that from the Dr.’s to the nurses, even the wonderful girls at the desk for check ins everyone is on their game , pleasant, knowledgeable & willing to help in any way! Give VTV 5Stars"

"I had LASIK at Vance Thompson Vision. My local eye doctor knew of Vance Thompson's reputation and I knew that I would be in good hands. I was treated like a VIP from the moment I arrived, until the moment I left to catch my flight back home. I am so grateful to Dr. Berdahl and his team at VTV for my new vision, and giving me more of my life back."

"Everything about the experience was great. The staff is so pleasant and welcoming, from the checkin to the checkout. The surgery staff is exceptional in their ability to put you at ease, be informative as to the process and what to expect. Dr. Berdahl was down to earth and not aloof. He made me feel comfortable knowing I was in good hands. It was an overall excellent experience. The result is that I can see the world clearer, brighter and no longer in a sepia fog. I would not hestitate to recommend Vance Thompson Vision to my friends and family."
