| Six
months after a successful cataract and in the bag intraocular lens implant.
a. Patient A complains of decreased visual
acuity. Slit-lamp examination
reveals contraction of
the capsule with anterior movement of the implant.
There is no posterior capsule.
What is the likely refractive change?
b. Patient B also complains of decreased visual
acuity. Slit-lamp examination
reveals tilting of the
lens along the vertical axis ie 900 by
about 300.
Assuming the implant is
a 20.0D biconvex IOL and the patient was
emmetropic before the tilt
occurred, what is the spectacle prescription? |
