SIOUX FALLS, SD – November 09, 2026 – PRESSADVANTAGE –

Vance Thompson Vision, an ophthalmology practice in Sioux Falls, South Dakota, is highlighting the surgical record and research contributions of Dr. John Berdahl, a board-certified ophthalmologist at its Sioux Falls clinic who has performed more than 50,000 eye surgeries and authored more than 120 peer-reviewed articles. Dr. Berdahl is among a small group of U.S. surgeons fellowship-trained in cornea, glaucoma, and refractive surgery, and his published work focuses on the fundamental causes of glaucoma, minimally invasive glaucoma surgery, and astigmatism management during and after cataract surgery. His Sioux Falls patients have access to LASIK, PRK, cataract surgery, cornea treatment, and glaucoma care delivered by a surgeon whose research has contributed to technologies used across each of those categories.

Patients throughout Sioux Falls, Brookings, Mitchell, Watertown, and Yankton seeking LASIK, cataract surgery, cornea care, or glaucoma treatment receive care at the Sioux Falls clinic. Dr. Berdahl’s glaucoma work in Sioux Falls has included involvement in more than 100 FDA-monitored clinical trials and the founding of Balance Ophthalmics, which developed a non-surgical, non-pharmacologic device to lower intraocular pressure for glaucoma patients. The Balance Ophthalmics device received FDA approval in 2024 and represents the first FDA-approved non-surgical, non-pharmacologic option of its kind for lowering eye pressure in glaucoma management. Dr. Berdahl was also a member of the NASA/NSBRI Vision for Mars team, which studied the safety of pressure manipulation around the eye.

In addition to his FDA clinical trial work, Dr. Berdahl has authored more than 35 book chapters and co-invented the MKO Melt, a sedation option used during cataract surgery at the Sioux Falls clinic that does not require an IV or opioids. He developed Interfeen, a rare-disease drug for ocular conditions, and created astigmatismfix.com, a calculator that, according to Vance Thompson Vision, has helped tens of thousands of surgeons address residual astigmatism following cataract surgery. He also co-founded ExpertOpinion.MD, an online resource where patients can request second opinions from specialty experts. Patients across the Sioux Falls service area, including Brookings and Watertown, receive cataract and glaucoma care at a Sioux Falls practice where several of these tools were developed.

“Patients place real trust in us during vulnerable moments, and that trust has shaped how I approach both surgery and research,” said Dr. John Berdahl, board-certified ophthalmologist at Vance Thompson Vision in Sioux Falls. “Whether the work is performing cataract surgery, treating glaucoma, or developing a non-surgical option for patients who need pressure-lowering therapy, the aim is to bring rigorous science to the decision in front of the patient.”

Dr. Berdahl’s professional recognitions include the 2026 American Glaucoma Society Innovator Award, the 2024 Chester B. McVay Award for Excellence in Teaching and Research from the USD Sanford School of Medicine, the 2020 Lans Distinguished Award from the International Society of Refractive Surgery, the 2019 Senior Achievement Award from the American Academy of Ophthalmology, the 2013 American Academy of Ophthalmology Achievement Award, and the 2008 Claes Dohlman Award for Most Outstanding Cornea Fellow at Harvard University. He completed his medical degree at Mayo Medical School, his ophthalmology residency at Duke University, and his cornea, glaucoma, and refractive fellowship at Minnesota Eye Consultants. The Ophthalmologist magazine named him to its Top 100 Most Influential People in Ophthalmology Worldwide list in both 2018 and 2022, and he is a founding member and past president of the Vanguard Ophthalmology Society.
