A camera CMOS dies at 1–2 µJ pulse, this same pulse energy reaches the cornea. If a sensor has fried, that means the dose to your eye is already in the zone of cataract creation. Human corneal endothelial cells do not regenerate. If the endothelium is damaged, stromal fluid accumulates and opacity can progressively over months/a year from one hit. You might never know what caused it.
