When using a lid manipulation to assist in "popping" a rigid lens off the eye,
the wearer should first make sure that the:
a) lower lid meets the lower part of the cornea
b) lens is resting on the cornea, where the fissure is widest
c) edge of the lens has been located with a penlight
d) lens is resting on the sclera, where the tissue is widest - ANS ✓b) lens is
resting on the cornea, where the fissure is widest
The most effective way to remove a soft contact lens that has adhered to the
cornea is to:
a) firmly press the lids against the sclera with fingertips, release, then blink
the lid closed firmly
b) gently pinch the lens directly off the cornea with clean fingertips
