How do we recenter a displaced lens?

• A. If displaced inferiorly or superiorly use lid margin to move back onto cornea
• B. If displaced temporally or nasally, have them look away from the contact lens, grasp lens, then look towards lens
• C. Remove the lens and reinsert
• D. Tilt the lens and rotate it

Answer: (A)

When a gas-permeable lens settles off-center up or down, the best first move is to use the lid margin as a gentle lever to slide the lens back onto the central cornea. The eyelid margin provides a soft, controlled surface to push the edge of the lens toward the center without pinching the eye or applying direct pressure to the cornea. With clean hands, you can lightly bring the upper or lower lid into contact with the displaced edge and guide the lens back into place, watching to ensure it centers smoothly on the cornea.

This approach works well for vertical displacement because the edge of the lens tends to escape the central area when it rides up or down, and the lid margin helps redirect it without removing the lens. Other methods described for different scenarios aren’t as appropriate here: attempting to grab and reinsert the lens is more disruptive and unnecessary if the lens can be repositioned with the lid, tilting or rotating the lens doesn’t reliably recenter it and can risk edge damage or discomfort, and gaze-based repositioning is not a consistent method for vertical displacement and may not center the lens properly. If the lens remains displaced or comfort is affected after attempts, remove and inspect the lens, and seek professional help if needed.
