The integration of a flashpoint (LED-based) navigational strategy (Flashpoint, integrated technologies, Boulder, CO) enables the capacity for 3D tracking at the central axis of the magnet, which facilitates a spherical imaging area of Ø30 cm (Moriarty et al., 1996; Lipson et al., 2001; Albayrak et al., 2004). Increased patient access was made possible via the enhanced cooling of the magnetic coils through the use of niobium tin, and thermal shielding that incorporated a dual-stage cryocooler, which negated the necessity for liquid helium baths. A customized vertically positioned microscope and a range of MR-safe surgical instrumentation and integrated anesthesia ventilators and monitors were developed to be accommodated by this system. Further, a number of LCD screens were arranged in close proximity to the surgeons to allow easy viewing of the acquired imagery (single-plane imagery is typically acquired within 60–120 s) (Albayrak et al., 2004).

After ocular examination and completion of the questionnaires, study participants were subjected to tear sampling, according to a routine non-invasive and non-anesthetized tear collection (eye-flush procedure; Micera A et al. 2016). Briefly, subjects underwent the administration of 30 μL sterile balanced salt solution (BSS; Alcon Laboratories Inc., Fort Worth, TX) followed by a fast tear collection with a sterile single-wrapped plastic micropipette (PBI Intl., Milan, Italy). Tear samples were quickly poured in a cocktail of protease inhibitors (Pierce Biotechnology, Rockford, IL) and stored at −20°C until delivery to Lab-Unit by using an isothermal cage (CryoCooler; Starlab Int GmbH, Ahrensburg, Germany).
