Research Information

Research Interests

Dr. Loretta Szczotka-Flynn is recognized as an Expertscape Expert in Contact Lenses for being in the top 1% of scholars with published work about Contact Lenses over the past 10 years. Her major research interests include contact lens associated corneal inflammation and infection, keratoconus, and corneal transplantation which have been funded by the National Eye Institute (NEI), a division of the National Institutes of Health (NIH). She also received significant funding from the American Optometric Foundation and industry. She participated in an eight-year study on keratoconus, the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study from 1996 to 2004 where she was principal investigator for the site at Case Western Reserve University and University Hospitals. She was principal investigator of a longitudinal study on extended contact lens wear complications, the Longitudinal Analysis of Silicone Hydrogel (LASH) Contact Lens Study, also funded by the NEI and part of her PhD Dissertation. Her other research interests include contact lens related biofilms which were funded in part by Prevent Blindness America and the CLAO Educational Research Foundation. She recently completed, along with Dr. Jonathan Lass in the Department, the NEI funded Cornea Preservation Time Study where she was Director of the Coordinating Center. This study enrolled 1,330 participants across 40 centers in the U.S to study the effect of donor preservation time on graft success in endothelial corneal transplants. Twelve publications in high profile journal have resulted from this work changing eye banking and keratoplasty practices. In 2018-19 she was funded by NEI and Alcon Laboratories to study the genetic susceptibility to contact lens associated microbial keratitis, together with colleague Sudha Iyengar, PhD.
