OBS

Pour (...) stabiliser [les lentilles à surface antérieure de forme torique (2 rayons différents] et éviter la rotation de la lentille sur la cornée, on a eu recours soit à un "troncage" de la partie inférieure de la lentille, soit à un épaississement de cette même partie inférieure pour obtenir un effet de ballast; mais dans ce cas, on augmente le poids de la lentille.
