What is the number one cause of GP lens dropout?

• A. Discoloration
• B. Discomfort
• C. Cleaning difficulties
• D. Lens loss

Answer: (B)

The main idea here is that patient comfort drives whether someone continues wearing gas-permeable lenses. GP lenses sit on the eye and rely on a stable tear film and a smooth edge—any irritation from a rough edge, poor lens fit, or dryness can make wearing uncomfortable. When discomfort is persistent, wearers shorten or stop wearing the lenses, so dropout tends to track with comfort issues more than with other problems. Discoloration, while not ideal, doesn’t inherently prevent wearing and is rarely the sole reason someone stops using GP lenses unless it accompanies irritation. Cleaning difficulties can be frustrating and may lead to improper care or lens damage, but with proper instruction many wearers overcome this, so it’s not typically the top reason. Lens loss is disruptive and unfortunate, but it occurs less frequently as the primary cause of long-term dropout compared to ongoing discomfort.
