If a SCLs wearer has problems with deposits, what should they be refit into?

• A. Silicone hydrogel
• B. PMMA
• C. Hydrogel
• D. Any GP material

Answer: (D)

Deposits on soft lenses are often tied to the lens material and how tear film proteins and lipids interact with it. Gas-permeable lenses provide a different surface and tear-transport dynamics, which tend to resist the way deposits cling to soft polymers and are easier to clean with standard rigid-lens care regimens. Because the goal is primarily to switch away from the soft material that’s prone to deposits, the specific GP polymer isn’t the critical factor—any gas-permeable material will typically offer the deposit-control benefit. The clinician will choose a GP lens and fit it to the eye’s shape and prescription, but the key idea is moving to a GP lens rather than sticking with a soft material.
