Volk Optical SLT Lens Distributor Product Presentation December, 2009
SLT Lens • Lens designed primarily for selective laser trabeculoplasty (SLT) treatment of glaucoma • Lens competes with Ocular Instruments Latina SLT Gonio lens • Lens completely meets requirements of SLT treatment guidelines and can be used in place of Latina lens • Specifications: magnification 1.0x, laser spot 1.0x, facet angle 63º, contact diameter 15mm • Lens can be used for all other trabeculoplasty procedures e.g ALT, MDLT, PLT • Link to lens page on Volk Optical website
SLT • SLT is a relatively new laser procedure to lower IOP in glaucoma patients • SLT is replacing Argon Laser Trabeculoplasty • Circular green laser treatment spots 400 microns in diameter are applied to 360º, 180º or 90º of the trabecular meshwork (TM)
SLT treatment lens guidelines • SLT lens should have unity (1x) magnification with the laser treatment spot fixed at 400 microns to cover the whole width of the trabecular meshwork. • SLT lens should not distort laser beam so that treatment spot at the TM is circular. • Lens should allow clear visualisation of the TM • The Volk SLT lens meets all of the above guidelines and may be used in place of the Latina lens
SLT Lens Features • Lens has 1x magnification • Curved upper lens surface ensures laser beam profile is circular at TM • Large internally reflective facet provides unmatched view of the angle • All internal surfaces except internally reflective facet are blackened eliminating light scatter • Lens may be used for all other trabeculoplasty procedures e.g ALT, MDLT, PLT
