If the lens is placed on scleral, what should the patient do to help sealing?

• A. have them look in the direction of the lens
• B. blink rapidly
• C. look straight ahead
• D. look away from the lens

Answer: (A)

When a scleral lens sits on the sclera, sealing depends on the edge of the lens settling evenly against the eye and the tear reservoir underneath helping create a suction seal. Asking the patient to look in the direction of the lens helps the eye move in a way that reduces eyelid interference and allows the lens edge to align and settle more smoothly against the sclera. This position promotes even distribution of the tear layer under the lens and enhances the suction seal at the edge. Looking straight ahead or away can cause the eyelids to shift in ways that disrupt the edge fit, and blinking rapidly can break the seal by redistributing tears or loosening the lens.
