← ScienceWhich outcome results when intense, focused, laser light ablates corneal tissue?
A)Plasmas generate shockwave expansion✓
B)Acoustic waves induce cavitation
C)Surface tension minimizes debris
D)Rapid cooling induces phase change
💡 Explanation
Laser ablation generates a hot, rapidly expanding plasma because the laser light's energy is absorbed by the corneal material which generates extremely fast vaporization causing plasma formation and a resultant shockwave. Therefore, a shockwave occurs, rather than cavitation or debris minimization, because heat transfer dominates here under pulsed irradiation, rather than surface tension or lower-energy phenomena.
