Which contact lens materials are most associated with contact lens–related ptosis?

• A. Corneal GP and soft CLs
• B. Rigid gas permeable lenses only
• C. Soft contact lenses only
• D. Hybrid lenses

Answer: (A)

Ptosis from contact lens wear is driven by mechanical interaction between the lens and the upper eyelid. When a lens sits on or rides against the upper lid with each blink, sustained lid contact and pressure can alter lid mechanics over time, sometimes affecting the levator aponeurosis or lid tone and leading to a droop. Corneal rigid gas-permeable lenses are relatively rigid and have a more prominent edge, which can sit on the upper lid and create considerable lid–lens contact. Soft contact lenses, though flexible, are worn across the lid margin for long periods in many users, so continuous lid interaction and friction can also contribute to lid strain and changes in lid position. Together, these two material types cover the main scenarios where mechanical forces from the lens are most likely to influence lid position, making them the ones most associated with contact lens–related ptosis. Rigid gas permeable lenses alone would miss the contribution from soft lenses, soft lenses alone would miss the contribution from rigid lenses, and hybrid lenses, while they can interact with the lid, do not show a stronger or more characteristic association than the combined GP and soft categories. If ptosis develops, reassessing lens fit, edge design, and wear time is important, with consideration of switching lens type or reducing wear to see if the lid position improves.
