Volk Optical
Reduces microscope working height, maximizes working space during vitreoretinal surgeryMentor, Ohio (April 19, 2011) – Volk Optical has built on its recently launched manually operated MERLIN® with a new Condensing Lens Assembly (CLA). This new option provides vitreoretinal surgeons the same detailed retinal views through the microscope, with the convenience of fully automated operation.
The MERLIN® provides precise control of non-contact lens position and focus for clear, crisp views during vitreoretinal surgery. With the CLA, lens positioning is system directed via a footpedal or the device’s lens positioning unit (LPU). When the LPU is swung into the surgical field bringing the Volk lens into position, the CLA automatically moves the condensing lens into the optical pathway to provide crisp retinal views. A footpedal control for the CLA is also available if preferred. With the condensing lens in place, microscope working height is reduced and refocusing between corneal and retinal views is minimized.
A low profile design minimizes the microscope’s stack height. The ROLS¥ is available in a manual configuration, or a foot switch operated powered version. The unit installs easily and can be removed quickly for cleaning and sterilization.
The LPU is fully rotational around the optical axis for optimal lens position in relation to the patient. The LPU and lens swing completely out of the surgical field when working on the cornea, maximizing space for surgical manipulation.
Compatible with all major surgical microscopes, with Volk’s new ROLS¥ (Infinity) reinverter, and the choice of three lenses, the modular MERLIN® system is the most advanced method for non contact retinal viewing. Volk’s ROLS8 allows users to adjust the prism to fit each individual microscope’s optical pathway, reducing image shift and vignetting when engaging the optical prism.
The MERLIN® lenses include: a wide angle with the widest field of view available; a small diameter wide angle exclusive to Volk for working with narrow-browed patients; and a mid field with higher magnification for more detailed examination of the posterior pole to the equator. The autoclave sterilizable glass lenses offer the higher optical quality and lower lifetime costs than comparable systems using disposable lenses.
