Meet our Doctor and Staff at Lander Vision Source


Dr. Kortny Lancaster, O.D.

Dr. Lancaster attended the Kentucky College of Optometry in Pikeville, KY. Here he learned full-scope eye care and advanced laser procedures. While in school he testified to the Wyoming legislature to help advance and pass the bill for advanced therapeutics and use of laser procedures. Dr. Lancaster is excited about his future here in this community to meet its residents and to help deliver the best eye care.

Dr. Lancaster purchased Lander Vision in August of 2023 from Dr. Mikel Weideman and looks forward to serving our community with the same values and strives for excellence in patient care and customer service as his predecessor.

When he isn’t in the office, you can find him in the outdoors with his family. He enjoys camping, fishing, and exploring new trails on his mountain bike. He also loves a good book and will never turn down Reese’s peanut butter cup. Dr. Lancaster and his wife, Briana, have three adorable children, Cooper, Kohen, and Tessa.
