Dr Samir Asad, 63, had denied assaulting the women in separate private examinations.
The Iraqi consultant’s first victim described how Asad, who was working as a locum, told her to hold on to a table and loosen her belt and jeans while he stood behind her.
The mother-of-two, now 60, said Asad held her from behind during the examination in a room at Crosshouse Hospital in Ayrshire and tried to touch her intimately.
He then cupped her left breast in his hand, and when she turned around, she saw that his trouser zip was down, Kilmarnock Sheriff Court heard. Asad, a chest specialist, had no stethoscope and took no notes during the incident, his victim said.
A second female patient was about to be discharged from Hairmyres Hospital in East Kilbride, Lanarkshire, when Asad asked to examine her. She said he placed his hand on her midriff then moved it slowly down to her genitals, keeping it there for 30 to 45 seconds.
Asad, now of Putney, London, was found guilty of sexual assault and committing indecent acts on the pretext of carrying out a medical examination in December 2008 and December 2010.
