Evaluation of an intra-operative tracking system for toric IOL positioning

Toric IOLs that correct corneal astigmatism are introduced more widely to cataract surgery. Key for success is precise alignment of the cylindrical axis of the IOL with the astigmatic axis of the cornea. In this study an intra-operative marking method will be analysed to show if intra-operative marking results in a higher precision of the postoperative IOL alignment.
