title: Laser-assisted marking for toric intraocular lens alignment.
abstract: We describe a technique of 3-dimensional spectral-domain optical coherence tomography-controlled laser-assisted corneal marking for toric intraocular lens implantation. To facilitate accurate alignment, the technique creates 2 perpendicular intrastromal incisions (width 0.75 mm) using an image-guided femtosecond laser. This was performed in a case series comprising 10 eyes of 10 patients. No posterior corneal perforation or epithelial alterations occurred. The incisions were plainly visible under the operating microscope, and no optical phenomena were reported 6 weeks after surgery. Laser-assisted marking can be performed safely and has the potential to enable precise axis marking.
