Could a common diabetes drug slow cataracts?
NCT ID NCT07176338
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study looks at whether metformin, a standard diabetes medicine, gets into the lens capsule of the eye and can slow the growth of lens cells that cause cataracts. Researchers will collect blood and lens tissue from 40 people with type 2 diabetes and age-related cataracts who already take metformin. The goal is to measure metformin levels in the lens and see if it reduces lens cell growth in lab tests.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
metformin
What this could lead to
If successful, this could point toward a way to slow cataract formation in people with diabetes.
What could go wrong
This is a very early, small pilot study (40 people) that only tests cells in a lab, not in the eye. It may not lead to any treatment.
