About the Editors

Ming Wang, MD, PhD is the Director of Wang Vision Cataract and LASIK Center in Nashville, TN, Clinical Associate Professor of the University of Tennessee, Nashville, TN.

Dr. Wang graduated from Harvard Medical School and Massachusetts Institute of Technology (MD, magna cum laude) in Boston, MA, holds a doctorate degree in laser spectroscopy, and completed his residency at Wills Eye Hospital in Philadelphia, PA and his corneal and refractive surgery fellowship at Bascom Palmer Eye Institute, Miami, FL. He is an editorial board member of Cataract and Refractive Surgery Today and Refractive EyeCare.

A former panel consultant to the United States FDA Ophthalmic Device Panel and a founding director of Vanderbilt

Laser Sight Center, Nashville, TN, Dr. Wang published a paper in the world-renowned journal Nature. This was followed by his editing 4 ophthalmic textbooks: Corneal Topography in the Wavefront Era: A Guide for Clinical Application (SLACK Incorporated: Thorofare, NJ; 2006), Irregular Astigmatism: Diagnosis and Treatment (SLACK Incorporated: Thorofare, NJ; 2008), Corneal Dystrophies and Degenerations: A Molecular Genetics Approach (Oxford University Press: New York, NY; 2003), and Keratoconus and Keratoectasia: Prevention, Diagnosis and Treatment (SLACK Incorporated: Thorofare, NJ; 2010). Additionally, he has published over 120 papers and book chapters.

Dr. Wang has several US patents for his inventions of new biotechnologies to restore sight, including an amniotic membrane contact lens, an adaptive infrared retinoscopic device for detecting ocular aberrations, and a digital eye bank for virtual clinical trials. He is currently one of three investigators in the United States conducting an FDA-regulated clinical trial to treat age-related loss of near vision (presbyopia). He introduced the femtosecond laser to China, and performed China’s first LASIK procedure using this laser in 2005. He also performed the world’s first femtosecond laser-assisted artificial cornea implantation (Alphacor), and the first Intacs procedure in the United States using a new version of Intacs for keratoconus.

Dr. Wang was a recipient of the Academy of Ophthalmology Honor Award, as well as the Lifetime Achievement Award of Association of Chinese American Physicians.

As the founding president of the Tennessee Chinese Chamber of Commerce, Dr. Wang founded a 501c(3) nonprofit organization called the Wang Foundation for Christian Outreach to China.

Dr. Wang specializes in refractive cataract surgery; keratorefractive surgery; corneal and external diseases, including

keratoconus; and anterior segment reconstructive surgeries with the amniotic membrane, stem cell, and keratoprosthesis. He runs a busy international referral clinic for post-LASIK and postcataract surgery complications. He founded another 501c(3) nonprofit charity, the Wang Foundation for Sight Restoration, which has also helped patients from over 40 states in the United States and 55 countries worldwide with all sight restoration surgeries performed free of charge.

Dr. Wang is a champion amateur ballroom dancer and a former finalist in the world ballroom dance championships in the open pro-am international 10 dance. He plays the Chinese violin (er-hu) and accompanied country music legend Dolly Parton on her CD Those Were the Days. Dr. Wang organized an annual classical ballroom dance sight charity event, the EyeBall, which is now in its 6th year, and has drawn attendees from all over the United States and around the world.

Tracy Schroeder Swartz, OD, MS, FAAO currently serves as Center Director of VisionAmerica in Hunstville, AL where she practices consultative optometry, specializing in ocular surface disease and dry eye. Originally from Wisconsin, Dr. Swartz attended Indiana University in Bloomington for her undergraduate education. During optometry school, she served as an assistant instructor for the Biology department and became interested in pediatrics and strabismus.

After completing her doctorate, she pursued a master’s degree in Physiological Optics, specializing in pediatrics. She served as faculty at the IU School of Optometry for 4 years, and earned the Indiana Chapter of the American Academy of Optometry Gordon Heath Fellowship in 1996.

After completing her master’s, she relocated to Metro DC, where she specialized in refractive and corneal surgery, and earned her Fellowship in the American Academy of Optometry. She later joined Wang Vision Cataract and LASIK Center in Nashville, TN. Here she served as Director of Clinical Operations, Residency Director for the Optometric Residency Program, and adjunct faculty to Indiana University School of Optometry. While there, she edited 2 textbooks with Ming Wang, MD, PhD: Corneal Topography in the Wavefront Era: A Guide for Clinical Application (SLACK Incorporated: Thorofare, NJ; 2006) and Irregular Astigmatism: Diagnosis and Treatment (SLACK Incorporated: Thorofare, NJ; 2008), as well as authored numerous book chapters on refractive surgery, topography, aberrometry, and anterior segment disease. She served as Co-Editor for the literature review column for Cataract and Refractive Surgery Today from 2003 to 2008, and now serves on the editorial board for Optometry Times.

She left Nashville for Huntsville, AL where she became the Center Director for VisionAmerica. She edited 2 textbooks, Keratoconus and Keratoectasia: Prevention, Diagnosis and Treatment (SLACK Incorporated: Thorofare, NJ; 2010) followed by Cornea Handbook (SLACK Incorporated: Thorofare, NJ; 2010). She is a board member of the Optometric Council for Refractive Technology, is a diplomat of the American Board of Optometery, serves as Adjunct Faculty for the University of Waterloo School of Optometry in Waterloo, Ontario, Canada, and tries to be the best soccer mom she can.
