Answer :
Final answer:
The excimer laser's strong absorption by the cornea concentrates energy for greater accuracy in vision correction and prevents damage to the lens and retina.
Explanation:
Strong absorption of the excimer laser's 193-nm electromagnetic radiation by the cornea helps concentrate energy in a thin layer, enabling precise reshaping to correct vision defects in laser vision correction procedures. This focused energy allows for greater accuracy in reshaping the cornea.
The strong absorption limits damage to the lens and retina of the eye by confining the energy to the cornea, preventing it from reaching and harming these delicate eye structures.
