What is a contact lens suction cup?
A suction cup (plunger) is a handling tool for controlled insertion or removal of rigid gas permeable (RGP), scleral or hybrid contact lenses. Most plungers are made of vulcanized dry natural rubber (latex-free) and reduce direct finger-to-eye contact.
Which lens types are supported?
- Scleral lenses: larger lenses resting on the sclera
- RGP lenses: rigid gas permeable lenses
- Hybrid lenses: rigid center with a soft skirt
- Soft lenses: dedicated non-suction tools with soft gripper pads (Soft Short) or slim insertion aids (Soft Slim)
- Ortho-K & CRT lenses: overnight rigid lenses
- Prosthetic eyes: larger suction surface for ocular prostheses
Safe use & care
- Wash hands with water and mild, lotion-free soap and dry with a lint-free towel. Make sure the lens is centered on the eye before touching it with the tool.
- Never place a suction cup directly on the uncovered cornea or sclera.
- Follow the product-specific instructions for your model (vented squeeze shaft vs. non-vented cup) and your eye care specialist's guidance.
- Clean natural rubber tools with warm water and mild, lotion-free soap (or as directed by the manufacturer) and air dry. Do not use alcohol, heat or harsh disinfectants unless permitted by the manufacturer.
- Inspect your tool regularly for wear or tears and replace a damaged tool immediately, or according to your specialist's replacement schedule.
