The Virgilio Galvis Ophthalmological Center as a High Technology Center included within FOSCAL is part of the practice scenario of the ophthalmology residency programs of the teaching-care agreements with the Industrial University of Santander UIS and the Autonomous University of Bucaramanga UNAB. Additionally, also endorsed by the Autonomous University of Bucaramanga UNAB, it offers a one-year fellowship program in Anterior Segment, Cornea and Refractive Surgery.

When reviewing SCORPUS, which is one of the most recognized scientific article databases, two researchers from the Galvis group and A Tello with 120 Publications are among the list of researchers with the highest production affiliated with the Autonomous University of Bucaramanga.

The most cited ophthalmology article by Colombian authors in the last 6 years, classified as the fourth most cited in the magazine “Eye” of the United Kingdom within the same time of publication, and with more than 230 citations registered in Google Scholar, was published on the topic of keratoconus by researchers at the Virgilio Galvis Ophthalmological Center, in association with international researchers.
