I don't think this is totally accurate. My eye doctors have never bought into the idea that the older "extended wear" contacts really can be worn 24/7 without causing problems. I did so against advice and was lucky. If a person wears them just during the day and takes them out at night, it should be fine.
But there is a new kind of extended wear contacts out called "Night & Day" and they are supposed to let many times more oxygen in than previous soft lenses. But my opthalmalogist still won't let me sleep in them regularly. Sigh. The web site says they are suitable for up to 1.50 diopters of astigmatism so they may not work for ABBA.
But even regular contact lenses (some of which do work for greater astigmatism) let in oxygen.
