Docking the eye to the system means connecting the eye to the laser. This is done via a patient interface. The patient interface utilizes suction to stabilize the eye and maintain a clear optical pathway for imaging and laser delivery. The goal during suction is to obtain a clear and stable image during the laser treatment while controlling the increased intra ocular pressure and the image quality. Each platform has a specific patient interface, for example, with the Catalys, docking is accomplished with a liquid filled interface which allowed a good cornea visualization during docking. The LenSx uses a curved applanated interface, which can create posterior corneal folds which can interfere with the ability to image and cut tissue effectively.

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
