Three-Dimensional Evaluation of Accommodating Intraocular Lens Shift and Alignment In Vivo

Quantitative 3-D anterior segment OCT allows full evaluation of the geometry of eyes implanted with A-IOLs preoperatively and postoperatively. High-resolution OCT measurements of the Crystalens 3-D positioning revealed small (and in many patients backward) A-IOL axial shifts with both natural or drug-induced accommodation, as well as tilt changes with respect to natural lens and accommodative effort.
