what do cyclops, capt kirk, & ultraman have in common?
yeah, they blasted their enemies with laser. when we were kids, it was a cool to possess such powers & these fictional characters were hero-worshipped week in & week out with our patronage in front of the TV.
well, lasers have come a long way since & their role these days are more beneficial than destructive. remember LASIK? now, it's even used to blast kidney stones & resect prostates. the flavour of the month seems to be green-light laser..
the machine generating the laser is on the left while the patient(all draped up) is on the right...
because of the intense brightness, special protective glasses need to be worn during its use....
...even for the patient.
the claimed advantage for laser in prostate surgery is less incidence of complications, eg.bleeding, urinary retention, impotence, & a shorter hospital stay. the cost, however, is a different matter altogether.
i wonder if kids will rate laser any less, now that it's mostly used to heal rather than destroy.
