The new Volk reinverter, ROLS® ∞ provides superior image quality with minimal image shift when used during vitreoretinal procedures. It has a unique feature to allow precise custom alignment with the microscope to minimize and eliminate image shift and vignetting. It is available in manual and powered versions.

The powered version is operated by footswitch to toggle between inverted and correctly oriented views without removing hands from the instruments. It may also be switched manually if needed.

ROLS is used with all surgical microscopes for viewing the retina with contact lenses, non contact lens systems and the new MERLIN® non contact viewing system.
