Clinical Research Fellowship | Pepose Vision Institute St. Louis

Fellowship Training

Pepose Vision Institute offers one-year and two-year Cornea/Vision Correction Fellowships for individuals who have completed an accredited U.S. residency program in ophthalmology. Our Fellows are involved in all aspects of the Practice. We provide surgical training and certification in the latest cataract, cornea and vision correction technologies, as well as high-volume pre- and post-operative patient interaction.

Fellows participate in a cooperative program with the University of Missouri-St. Louis School of Optometry, in which they provide pre- and post-operative co-management training to optometry students. Under the direct supervision of our cornea subspecialty trained PVI surgeons, Fellows perform laser vision correction surgeries/interventions for underserved individuals from East St. Louis and for first responders.

Clinical Research Fellowship

Pepose Vision Institute is engaged in an active clinical research program, largely in conjunction with developers of vision technologies around the world. PVI’s founder and Medical Director, Dr. Jay Pepose, has earned both an M.D. and Ph.D. and has published hundreds of peer-reviewed articles. He is currently Professor of Clinical Ophthalmology at Washington University School of Medicine. These unique features make our practice an ideal setting for training in clinical research.

One and two-year research fellowships are available. PVI will consider exceptional international candidates with research experience who have graduated from a foreign medical program and are applying to a U.S. ophthalmology residency program. All research fellows can expect to present at one or more national ophthalmology meetings, and share authorship in one or more publications during their training at PVI.

We always provide our patients with compassionate and customized care.

International Eye Banking Program

We provide grant support to enable one Fellow per year to travel to the United States to participate in the International Eye Bank Fellowship Program. The two week program was established at Pepose Vision Institute, in conjunction with Mid-America Transplant Services (MTS) of St. Louis, where Dr. Jay S. Pepose served as Medical Director of MTS Eye Banking. Its goal is to promote international eye banks and corneal transplantation – a sight-saving procedure that is the most frequently performed transplant in the U.S. — through the development of indigenous eye banks throughout the world, with particular attention paid to less-developed nations.

Historically, U.S. eye banks have tried to fill international cornea transplant needs by exporting excess corneal tissue; unfortunately, such efforts have been hindered by transportation logistics and the lack of international funds to cover U.S. tissue-processing expenses. The Pepose-MTS fellowship program provides the know-how to ophthalmologists who wish to develop state-of-the-art indigenous eye bank programs. As Dr. Pepose notes, “It is far more satisfying, efficient and effective to teach medical personnel to provide for themselves within their own communities.”

During the course of the two-week Fellowship, ophthalmologists with a special interest in eye banking receive instruction on managing and setting up an eye bank and retrieval network. Through this program, the International Fellow enjoys advanced training by MTS staff and Dr. Pepose, followed by participation in the National Eye Bank Association of America annual meeting. Previous recipients include Dr. Joselito Casimiro – The Philippines and Dr. Kunle Hassan – Nigeria.

Did you know Pepose Vision is also an advanced research facility?
