How does the DMV method remove GP lenses?

Explanation:
The DMV method relies on a suction cup to lift the gas-permeable lens off the eye. GP lenses sit on the cornea with a tear film seal, so removing them smoothly often means breaking that seal rather than pinching the edge. A small suction cup attaches to the lens and creates gentle negative pressure, allowing the lens to be lifted away from the surface in a controlled way. This minimizes trauma to the cornea and reduces the chance of tearing or bending the lens during removal. Irrigation doesn’t reliably break the seal, eyelid pressure on the cornea risks injury and discomfort, and tearing the lens out isn’t a safe or proper technique.
