Which lens modality is mentioned as a management option for dry eye?

• A. Scleral lenses
• B. Soft contact lenses
• C. Rigid gas permeable lenses
• D. Orthokeratology lenses

Answer: (A)

Scleral lenses are mentioned as a management option for dry eye because they vault over the cornea and rest on the sclera, creating a stable tear-filled reservoir that bathes and protects the ocular surface. This reservoir reduces lid-friction, minimizes tear evaporation, and keeps the cornea hydrated, which can significantly improve comfort and vision in patients with ocular surface disease or moderate to severe dry eye. Soft contact lenses can offer comfort as bandage lenses, but they don’t provide the tear reservoir and aren’t as effective for pronounced dry eye. Rigid gas permeable lenses sit on the cornea and don’t create the protective reservoir, making them less suitable for dry eye management. Orthokeratology lenses reshape the cornea overnight and are not used for treating dry eye.
