Fig. 15. The Graether ScrollFlex IOL from 1984 designed for sulcus or capsular bag placement was 14.0 mm in length and had a relatively stiff resistance to compression. Four-point optic fixation made it resistant to tilt or optic capture. Notice the interesting similarity of the compound curves in the C-flex IOL from Rayner (Fig. 35). (Courtesy of John M.
