Rotational stability of a toric intraocular lens: influence of axial length and alignment in the capsular bag.

Purpose: To evaluate the rotational stability of a toric intraocular lens (IOL) using purpose-designed software and to determine the influence of axial length (AL) and in-the-bag IOL alignment on IOL rotation.

Setting: Iladevi Cataract & IOL Research Centre, Ahmedabad, India.

Design: Prospective observational case series.
