Answer to Question 1

B
Keratitis is an inflammation of the cornea caused by irritation or infection. Artificial tears will reduce the irritation. Antibiotics can be given in the event of a bacterial infection. Eye shields and compresses are not indicated in the management of this condition.

Answer to Question 2

A
A PRK uses a laser to remove a thin layer of the cornea. The LASIK procedure uses a laser to reshape the cornea and replace the outer layer. Making tiny cuts in the cornea to flatten it refers to a radial keratotomy.
