New Study Links Pfizer COVID Shot to Eye Damage

A new peer-reviewed study out of Turkey is raising fresh concerns about the Pfizer-BioNTech COVID-19 mRNA vaccine — this time involving your eyes.

Scientists found that the shot may significantly alter the structure of the cornea, the transparent front part of the eye, which could have serious long-term impacts on vision, especially in those with pre-existing eye conditions.

What the Study Found:

  • Corneal thickness increased after the second Pfizer dose

  • Endothelial cell count dropped by 8% — these cells are vital for keeping the cornea clear and functioning

  • More cell size variation and fewer cells kept their healthy six-sided shape

  • All signs point to inflammation and cellular stress after vaccination

While these changes didn’t cause immediate vision problems in the short study window, researchers warn that over time, they could lead to conditions like:

  • Corneal edema

  • Bullous keratopathy

  • Permanent vision loss in severe cases

This is especially concerning for people with:

  • Prior cornea surgery

  • Fuchs’ dystrophy or other eye diseases

  • Low baseline endothelial cell counts

The study’s authors concluded the changes were “likely linked to the vaccine,” not random.

Using advanced corneal imaging, researchers analyzed 64 people before and after their Pfizer shots — and the results were clear: the eye’s inner layer changed, and not for the better.

📍 This comes on top of existing concerns about:

  • Myocarditis (especially in young men)

  • Pericarditis

  • New findings of autoimmune and neurological impacts

Once again, Pfizer’s COVID shot is under the microscope, and this time, it’s our vision that may be at risk.

While public health officials continue to repeat the “safe and effective” mantra, new science tells a different story.

Canadians deserve:

  • Transparency from Health Canada and provincial authorities

  • Informed consent based on the full picture of risks

  • Accountability from manufacturers and regulators alike
