3. 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)

4. 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

5. 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
