← ScienceWhich risk increases when a pulsed laser ablates corneal tissue?
A)Collagen fibril denaturation weakens the cornea✓
B)Lens disruption changes focal properties
C)Increased cavitation erosion weakens deep lamellae
D)Excimer plume condensation reduces transparency
💡 Explanation
Collagen denaturation elevates weakening because irradiation causes **protein unfolding** within the stroma, therefore reducing mechanical strength, rather than cavitation which is less influential there and doesn't impact other tissue or fluids.
