What are the primary ways physicians use lasers?
I’m not sure, but laser light can be pinpointed at specific small regions that a knife either cannot reach, or that a knife can’t do a fine enough (small enough) job on. An example: a laser can be used through the lens of the eye to treat problems on the eye’s retina (however, I’m not sure of the details of this, or any other procedure). I recently saw a TV news report where a laser was being used to remove skin that had been damaged by burns. The surgeon said the laser was more precise than a knife, and resulted in less scarring after the patient healed.
