Dynamic Workflow Proposal for Continuous Frameless Electromagnetic Neuronavigation in Rigid Neuroendoscopy.

Background: Ventriculoscopic neuronavigation has been described in several articles. However, there are different ventriculoscopes and navigation systems. Due to these different combinations, it is difficult to find detailed neuronavigation protocols.

Evaluation of rotation and visual outcomes after implantation of monofocal and multifocal toric intraocular lenses.

Purpose: To evaluate rotational stability and its influence on postoperative visual acuity of different monofocal and multifocal toric intraocular lenses (IOLs).

Methods: A prospective interventional study was designed. Ninety-one patients with a mean age of 71.
