**3.1 LenSX**

The LenSX laser is a standard unit that does not require external connections to water or gas. Recent updates have changed the diameter of the patient-interface, now called SoftFit PI, which allowed a 20% reduction in intraocular pressure (IOP), providing less discomfort for the patient (**Figure 1**). The SoftFit® interface has a soft lens insert in the interface that allows the reduction of corneal folds during the docking, and a better delivery of the laser beam [16]. The integrated anterior segment optical coherence tomography OCT provides real-time scanning from the corneal epithelium to the posterior lens capsule with a high-resolution video. This imaging system is able to either take a single OCT snapshot, or produce live continuous OCT images (**Figures 2**–**4**). Thanks to live OCT, surgeons can immediately check if the patient's positioning is adequate, reducing the risk of tilt during the docking procedure.
