Question 2

An older man tells a nurse, The doctor says I have something wrong with my eyes, something called presbyopia. Can you explain why I have this? I was always fortunate to have good eye-sight. The nurse formulates a response based on the knowledge that:
 
  a. the lens of the eye loses elasticity causing a loss of focus for near objects.
  b. the cornea of the eye becomes thicker and less curved causing an increase in astigma-tism.
  c. the lens of the eye increases in opacity causing a decrease in light refraction.
  d. the cornea of the eye forms a gray ring at the edges.

Answer to Question 1

ANS: A, B, C
Postcataract surgery the individual needs to avoid heavy lifting, straining, and bending from the waist. Fall prevention is also very important as is complying with eye drop administration. Main-taining strict blood sugar and blood pressure control is most important for diabetic retinopathy, not cataract extraction. There usually is not a dressing over the operative site, and not for 10 days.

Answer to Question 2

ANS: A
Presbyopia is the loss of focus for near objects, caused by a loss of elasticity and hence a loss of accommodation of the lens of the eye. All of the other options are normal age-related changes; however, they are not related to presbyopia.
