Rotational stability of the Toric Tecnis one-piece IOL: a pilot study

The rotational stability of a new Toric Tecnis one-piece IOL with C-haptic is in the focus of this pilot study. It is an aspheric acrylic toric IOL with a sharp optic edge design to inhibit PCO formation. The haptic design is supposed to ensure rotational stability. For astigmatism correction, an IOL rotation of 3° would result in a loss of astigmatism correction of 10% and rotation of 10° in a loss of one third of the correction.
