Scientists in Turkey studied 64 patients to measure changes in cornea thickness and endothelial cell density before and after administering the Pfizer COVID-19 vaccine. Results showed post-vaccine thinning of endothelial layers, suggesting the vaccine could temporarily weaken the corneal endothelium. While no immediate vision problems were noted, lasting changes could increase risks of eye conditions such as corneal edema and blurry vision, particularly in at-risk populations. Researchers emphasized the need for monitoring in those with existing eye issues and advised using specular microscopy for early detection.

Katharina Hartmuth emphasized the significance of completing the race despite facing significant challenges, including a substantial loss of vision during the latter half of the event.
