lenticular astigmatism

[OptiStudent]

I was told that irregular astigmatism (2 or more focal lines are formed that are not 90 degrees apart), is best corrected by RGPs compared to glasses or soft CLs. I understand how RGPs correct irregular corneal astigmatism because of the tear film that is formed. Another cause of irregular astigmatism is a titled crystalline lens. Are RGPs also the best correction for lenticular/internal irregular astigmatism? If so, why?Any help is appreciated in advance.
