Dr. Jan P.G. Bergmanson received his optometric training and PhD at the City University, London. In addition, he obtained a Doctor of Optometry degree from Pennsylvania College of Optometry. Currently, Dr. Bergmanson is Professor of Optometry at the University of Houston College of Optometry (UHCO), where he is the founding Director of the Texas Eye Research and Technology Center (TERTC). He has extensively researched and lectured internationally on subjects of corneal morphological response to contact lens wear, tear and ophthalmic solution effects on the ocular surface, histopathology of ocular tissues damaged by ultraviolet radiation, and the effects of the Excimer Laser on the cornea. In addition to private optometric practice, Dr. Bergmanson, certified in Texas as a Therapeutic Optometrist and as an Optometric Glaucoma Specialist, has provided patient care in several hospital and university clinics. Dr. Bergmanson is a Foundation Fellow of the College of Optometry in United Kingdom, where he remains licensed to practice, and a Fellow of the American Academy of Optometry, where he is a Diplomate in the Cornea and Contact Lens Section. He is a member of the Texas Optometric Association (TOA), American Optometric Association (AOA), Association of Contact Lens Educators, and International Association of Contact Lens Educators. He is a council member of the International Society for Contact Lens Research and a lifetime honorary member of the Swedish and Dutch Optometric Associations, to which he also serves as a consultant. Dr. Bergmanson is the recipient of the 1998 British Contact Lens Association Gold Medal Award, the 2002 Texas Optometric Association's Educator of the Year Award, the University of Houston College of Optometry 2003 Cora and J. Davis Armistead Faculty Teaching Award and the 2005 Swedish Optometric Association's Mark of Honor Award.
Research interests include Clinical Trials on new contact lens designs and material and ophthalmic effects on the ocular surface. Over many years, Dr. Bergmanson has maintained a research program on ultraviolet radiation effects on the eye and aidnexa and how to protect these tissues from such harmful irradiation. He is an active researcher in the area of the anatomy of the eye, while maintaining an interest in ocular histopathology. Current research in ocular pathology concerns in particular keratoconus and pterygium.
Dr. Bergmanson is a Diplomate in Cornea and Contact Lenses (American Academy of Optometry). Main clinical interest concerns advanced contact lens care and the diagnosis in treatment of ocular surface disease.
David A. Berntsen, OD, PhD, FAAO completed his Doctor of Optometry degree in 2002 at the University of Houston College of Optometry in Houston, TX. He then completed a Cornea and Contact Lens Advanced Practice Fellowship at The Ohio State University College of Optometry in Columbus, OH. The fellowship program combined a two-year residency with a Master of Science degree in Vision Science, which Dr. Berntsen completed in 2004. He then completed a PhD in Vision Science at Ohio State in 2009.
Dr. Berntsen's research interests include myopia, contact lenses, and aberrations of the eye. He conducted the Study of Theories about Myopia Progression (STAMP), a two-year clinical trial evaluating theories of juvenile-onset myopia progression. He has conducted adult and pediatric studies involving contact lenses and higher-order aberrations of the eye. Dr. Berntsen is the Principal Investigator of the University of Houston clinical site for the Bifocal Lenses In Nearsighted Kids (BLINK) Study, a multicenter randomized clinical trial sponsored by the National Eye Institute. The BLINK Study is a collaborative effort between the University of Houston and The Ohio State University that will determine whether commercially available soft bifocal contact lenses slow the progression of nearsightedness in children.
Injury to the corneal epithelium can occur through mechanical or chemical trauma, as well as through elective refractive surgeries (e.g., LASIK or PRK). Despite our current understanding that neutrophil recruitment to the injured cornea can be important for wound healing, many questions remain regarding the molecular mechanisms regulating neutrophil migration within the corneal stroma. Our research suggests neutrophil migration is influenced by molecular interactions with keratocyte (stromal cell) networks embedded between the stromal collagen lamellae. The hypothesis being evaluated is that PMN motility on keratocytes is regulated by inflammatory mediators (chemokines) and adhesion molecule-dependent interactions. Information gained from these studies will help delineate novel adhesive mechanisms underlying neutrophil migration in the injured cornea and this may define new targets for therapeutic treatment of ocular inflammation associated with injury or infection.
