a. A 18 year-old university student presents to the optician
one week before his
final examination complaining of intermittent
double vision and poor distance
vision. He was seen one month earlier and the
refraction was emmetropic.
i. What is the most likely diagnosis ?
ii. What treatment would you prescribe?
b. A 40 year-old myopic woman is recently prescribed soft contact
lenses for the
first time. She returned two weeks later and
complains that her reading vision is
not as good as with her glasses. Retest shows
her visual acuity to be 6/6 in both
eyes with the contact lenses and the lenses were
of the right prescription and
well-fitted. Why does she have problem reading
with her contact lenses but not
with her glasses?
