Answer to Question 1

ANS: B
In phototherapeutic keratoplasty (PTK), scar tissue is removed from the cornea with an excimer laser. PTK restores vision that has been blocked by scars from infection, injury, or an inherited condition.

Answer to Question 2

ANS: B
Enucleation is the complete removal of the eyeball and the severing of the muscular attachments. The muscle stumps are preserved in this procedure. A pocket can be formed for an artificial eye.
