Kareen Yeung Landerville, OD, FOVDR
Dr. Kareen Yeung Landerville was born in Canada and raised in North Dakota. She received her bachelors of science degree in Microbiology from the University of California, Davis in 1995 and completed her optometric training at the Southern California College of Optometry in 2002.
Dr. Landerville continued to practice in the southern California area while concurrently pursuing advanced post-graduate study in vision therapy, vision development and rehabilitation. She became a Fellow of the College of Optometrists in Vision Development (now Optometric Vision Development & Rehabilitation Association) in 2005. Dr. Landerville moved to Massachusetts in 2006 and spent several years practicing in New England, mentored by leading developmental and vision rehabilitation optometrists in the country. She returned to the west with her family to establish the Las Vegas Center for Vision Therapy, now Oasis Optics and Vision Therapy, in 2014.
Dr. Landerville's preliminary interest in the science of vision development arose during her time as an optometry student. However, it was participation in a course of vision therapy as a patient that cemented her desire to focus on this field as a health care provider. Following completion of her own treatment program as an adult, she was able to experience detailed stereopsis for the first time in her life. This allowed her to perceive the world in three dimensions. Clouds popped out of the sky, and she was finally able to perfect her tennis skills on the court!
In addition to her fellowship with the Optometric Vision Development & Rehabilitation Association (she is one of only three fellows in the state of Nevada), Dr. Landerville is board-certified in the treatment and management of ocular diseases. She is also active with the International Sports Vision Association, the Neuro-Optometric Rehabilitation Association, and the College of Syntonic Optometry. Because she has a dedication and commitment to education, Dr. Landerville has lectured for the Clark County School District, Nevada Optometric Association, and National Strength and Conditioning Association.
Dr. Landerville has a special interest in amblyopia and strabismus, post-concussion management, and sports vision training, working with elite and professional athletes. She is a consultant to the Vegas Golden Knights, Las Vegas Raiders, Las Vegas Aces, and UNLV Athletics. Dr. L lives in Las Vegas with her husband, daughter, and sweet golden retriever named Copley. In her spare time, she enjoys playing and listening to music, and spending precious time with her extended family.

Elizabeth Wright, OD, FOVDR

Dr. Elizabeth Wright is a Las Vegas native and a University of Nevada, Las Vegas graduate. She received her doctorate from the Southern California College of Optometry at Marshall B. Ketchum University in 2017. Dr. Wright completed a residency in Pediatrics, Vision Therapy and Neuro-Optometry, and was honored with an award in strabismus and amblyopia research. In addition, she has completed over 100 hours of continuing education in binocular vision, strabismus, traumatic brain injury, and visual perception.
Before applying to optometry school, Dr. Wright shadowed Neuro-Developmental Optometrists and was inspired by the powerful effect of these treatments. Dr. Wright shares, "I was excited that, as a developmental optometrist, I could provide a small change in a prescription, or a program of vision therapy, and in turn provide a significant and life changing impact. For example, I love the variety of people we can help and
-
take an average sports player and make them extraordinary
-
give back visual comfort and reading skills to those who have had head trauma
-
help families who are struggling with meeting individual education plans due to an underlying vision problem
-
take non-readers and transform them into book worms..."
She continues, "We give every patient the chance to reach their full potential. We find what's holding them back and work together between our doctors, your family, and the patient to overcome the visual obstacles that have been holding them back."
Dr. Wright has a special gift and interest in working with children on the autism spectrum and with special needs, connecting with them when no one else can and successfully guiding through evaluations and vision therapy. Dr. Wright is a fellow of the Optometric Vision Development & Rehabilitation Association, one of three fellows in Nevada. In addition, she is board-certified in the treatment and management of ocular disease. She lives in Henderson with her husband, and in her free time enjoys hiking Red Rock Canyon, as well as nature photography.
