Final answer:
Laser surgery provides the advantages of decreased pain, swelling, and bleeding, along with precise targeting of specific areas, but it is not advantageous in terms of expense as laser equipment can be costly.
Step-by-step explanation:
The benefits of using laser in surgical procedures include several advantages such as decreased pain, decreased swelling, decreased bleeding, and the ability to target difficult-to-reach regions of the body. Lasers create less bleeding because the high-energy light beam coagulates blood vessels as it cuts, which leads to less swelling and pain. Moreover, lasers provide precision that allows surgeons to target specific areas without causing damage to surrounding tissues, which is particularly useful in delicate surgeries such as those involving the retina, where a green argon laser is used to coagulate tissues containing blood effectively.
However, one of the drawbacks of laser surgery is the expense. Laser equipment and maintenance can be costly, and these costs may be passed on to the patient. Therefore, while the other statements (A, C, D, and E) correctly represent the advantages of laser surgery, the statement regarding expense (B) is not an advantage but rather a disadvantage.
