From what I found on-line for this “Dr. Fischer”, he is an optometrist (optometry doctor, OD), not an medical doctor (MD) or doctor of osteopathy (DO), who have far more training to become and ophthalmologist (eye surgeon). It is the MDs and ODs who would have taken that oath at graduation, that has replaced the Hippocratic Oath. This guy (”Dr.Fischer”) as an OD could do a basic eye exam and measure visual acuity, but not do surgery or deal with anything complicated—or probably even prescribe medications (though OD’s Rx’ing privileges vary from state to state). The subject of this article probably would have to see an MD/DO to get kind of treatment he will need.
Thanks for the additional clarification. What I know about doctors could fill a small sticky note- not much.
He has a shitty outlook on life which will require someone to, "clear up" for him.
