Which GP lens removal method is described as using a suction cup to lift the lens?

Explanation:
This item tests how suction-based removal works. The suction cup method uses a small suction cup placed on the GP lens; gentle suction creates a seal and lifts the lens off the tear film and cornea, allowing removal with controlled lifting rather than pinching. It’s particularly useful when the lens is adherent or when finger access is difficult, because the lift is less likely to compress or shear the cornea. Other techniques rely on pinching the lens edges or using lid motion to break the seal, without a suction device. So the approach described as using a suction cup to lift the lens is the suction cup method.
