The Flexlens Lens utilizes a back surface design, with 1.50D of prism ballast to stabilize rotation. There is a laser mark at 6 oclock to mark the location of the prism ballast. For those patients with high degrees of irregular astigmatism, they may have a more successful visual outcome with gas permeable lenses or the Flexlens Piggyback design.
