What issue can arise with lens removal, cleaning, and storage?

• A. Warpage
• B. Scratches
• C. Discoloration
• D. Tear

Answer: (A)

Rigid gas-permeable lenses rely on a precise curvature to sit correctly on the cornea. During removal, cleaning, and storage, if the lens dries out, is exposed to inappropriate solutions, or is handled roughly, it can deform. This warping changes the lens’s base curve and edge alignment, leading to a poor fit, unstable vision, and discomfort. Other problems—scratches from rough handling, discoloration from deposits, or tears from excessive force—are possible but are not as directly tied to the care steps as warpage. So, the issue most likely arising from removal, cleaning, and storage is warpage. To minimize this, use recommended solutions, avoid drying the lens, handle gently, and store in fresh, appropriate storage solution.
