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 25,000 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. His CV can be accessed here:

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.

Reviews

"I flew in from Seattle WA to have LASIK performed by Dr. Berdahl at Vance Thompson Vision. From the moment I walked in, I was greeted warmly greeted. Their lobby eschews a traditional waiting room configuration and instead is setup more like coffee shop, including fresh baked cookies, coffee, fruit, and soda. Everyone there was friendly and took time to answer any and all questions. They explained the procedure step by step, went over the aftercare instructions. The whole time my comfort was the primary concern. The outcome of the surgery couldn't have been any better resulting in 20/15 eye. I'm so thrilled to be glasses and contact free. Thank you Dr. Berdahl!"

"I am absolutely amazed with my vision after LASIK surgery at Vance Thompson Vision. Until I no longer had to wear them, I didn't realize how much contact lenses were irritating my eyes and making them feel dry. I had surgery in the late afternoon on a Thursday and was at work at 7am Friday morning with 20/15 vision. I cannot say enough about how wonderful my experience has been. I would recommend Dr. Berdahl and Vance Thompson Vision over and over again, it truly is a world class establishment!"
