Designed specifically for Selective Laser Trabeculoplasty procedures
Mentor, Ohio (January 25, 2010) – Tailored to the unique needs of Selective Laser Trabeculoplasty procedures, Volk Optical’s new SLT Lens provides detailed, high resolution views of the anterior chamber angle for examination and laser spot placement.

The Volk SLT Lens was designed specifically for Selective Laser Trabeculoplasty.

 
The SLT’s single internally reflecting surface, the preferred standard for SLT procedures, delivers 1.0x magnification, maintaining laser spot size and power density.  Its curved upper lens surface ensures the laser beam profile remains circular, for consistent laser spot placement.  The contact lens design, used with a coupling fluid, provides stability for laser delivery.  These qualities also make the SLT lens suitable for all laser trabeculoplasty procedures. 

High grade acrylic construction maintains superior resolution for the best possible image quality.  Internal surfaces around the lens are treated to eliminate light diffusion.  A smaller profile simplifies manipulation of the SLT lens, especially in a patient with a deep set eye or narrow brow.

High resolution extreme field indirect contact surgical lens
Mentor, Ohio (April 21, 2009) – For indirect image viewing of the entire retina during vitreoretinal surgical procedures, Volk Optical’s new HRX (High Resolution eXtreme field) Vit Lens offers unmatched imaging.  The super-wide field lens ensures visualization of retinal pathologies to the ora serrata with high index glass construction for crisp image quality.

For vitreo-retinal surgeons who prefer to conduct surgery with an indirect contact surgical lens and reinverter, the traditional standard has been the 127° field offered by Volk’s Mini Quad and the 134° field of the Mini Quad XL.  With this new lens, Volk has been able to expand the field of view to 150° for even greater peripheral visualization and treatment power at .43x image magnification. 

The HRX Vit lens delivers this super wide view without compromising image quality.  High grade, high refractive index glass ensures optical quality.  Volk’s patented double aspheric design maintains linear image magnification and image clarity across the entire field of view.

With a low profile and reduced size housing, the HRX Vit facilitates surgical procedures and instrument manipulation.  The lens is available in either a standard contact option or Volk’s patented SSV® (Self Stabilizing Vitrectomy) design.  SSV lenses contact directly to the cornea, eliminating the need for suture or stabilizing rings and reducing associated patient discomfort and surgical prep time.

High index glass delivers continuing unmatched image quality in new lens family
Mentor, Ohio (November 4, 2008) – Volk Optical, the leader in aspheric optics, has released the H-R Direct Image series of lenses for direct image viewing during vitreoretinal surgical procedures.  The lenses’ new glass construction delivers unmatched image quality in a robust design suitable for the rigors of continued steam sterilization.

Unlike competing glass and thermoplastic lenses, Volk’s H-R Direct Image lenses are specially developed from high index glass to handle harsh sterilization conditions without discoloration, degradation and deteriorating image quality and clarity.  This construction also delivers better image quality and wider fields than similar products.

The H-R Direct Image series is available in four styles.  The H-R Direct Bi-Concave delivers wider field (mid field) views for Air Fluid Exchange procedures, and the H-R Direct 20° Prism provides off-axis retinal views.  The H-R Direct 1X allows a wider field of view than traditional ‘flat’ lenses, and the H-R Direct High Mag allows visualization of central retinal pathology in greater detail. 

The Direct 1X and High Mag lenses are also available with a self-stabilizing design.  These lenses contact directly to the cornea, eliminating the need for suture or stabilizing rings and reducing associated patient discomfort and surgical prep time.

High resolution lens allows visualization of details approaching the ora serrata
Mentor, Ohio (May 14, 2008) – Volk Optical, the leader in aspheric optics, has released the H-R Wide Field Laser Lens, a new pan retinal lens for diagnosis and laser treatment.  Its high resolution imaging, coupled with an extremely wide field capability, provides detailed views for diagnostic and laser work.

The H-R Wide Field’s deep field of view reveals details as far out as the ora serrata and most importantly, is distortion free across the entire viewing area.  The combination of Volk’s patented double aspheric glass design with low dispersion™ glass ensures the highest resolution imaging across the entire viewing field. 

This superior viewing power is contained in a low-profile, reduced-size housing to simplify manipulation of the lens within the orbit.  The H-R Wide Field has been compared favorably to the popular discontinued Rodenstock Pan Fundus Laser lens, with an even wider field of view and better image quality.

The lens provides a .50x magnification, and a 2.0x laser spot magnification and is the best choice for widest field diagnosis and PRP laser treatment.  While the H-R Wide Field is a contact lens, requiring the added step of a coupling solution to the examination, it ensures clear visualization of retinal tears or lesions across the entire retinal surface.  No non-contact lens exam method is able to achieve this level of image clarity and detail.
