What is the purpose of releasing eyelids one at a time after lens placement?

• A. to prevent the lens from popping off
• B. to allow tear drainage
• C. to adjust lens orientation
• D. to improve patient comfort

Answer: (A)

Releasing eyelids one at a time helps the lens settle securely on the cornea and reduces the risk of dislodgement during the blink. When both lids close together, the rapid pressure and suction can push a newly placed lens off the surface. By letting one lid go first, the lens has a chance to seat with gentler, gradual forces from the tear film and eyelid, then the other lid can close to stabilize it. This makes it less likely the lens will pop off as the eye blinks. While better lid release can also aid comfort and positioning, the main purpose here is preventing the lens from being dislodged.
