When should the DMV (or suction cup) method be used with GPs?

• A. If deemed essential (like with a patient with CP)
• B. For every patient
• C. Only after trying other methods
• D. Never

Answer: (A)

The main idea here is that the suction cup (DMV) handling method is a backup technique you use only when standard fingertip methods aren’t feasible or safe for the patient. It’s particularly helpful for patients with limited hand function or motor control, such as someone with cerebral palsy, where managing and inserting a small GP lens with fingers can be difficult or risky. Using the suction cup can provide a more controlled, secure way to grip and move the lens without requiring delicate fingertip manipulation.

This method isn’t a routine step for every patient. It introduces a different handling process and requires proper training, equipment, and careful technique to avoid lens damage, contamination, or ocular injury. So it should be reserved for situations where conventional methods can’t be used safely or effectively, and it’s essential to the patient’s ability to wear the lens properly.
