# What Causes Regression After Laser Eye Surgery?

Regression occurs due to:

- Epithelial remodelling¹
- Biomechanical redistribution¹
- Ongoing myopic shift in young patients²

Hyperopic treatments show higher regression due to central epithelial thickening¹.

Regression is biological, not technical error.
