Pattern Scanning Laser Trabeculoplasty (PSLT)
(optional)
Indications for Use:
Pattern Scanning Laser Trabeculoplasty (PSLT) software is intended for use with
the PASCAL Synthesis TwinStar for procedures in trabeculoplasty in Open Angle
Glaucoma.
Description:
Pattern Scanning Laser Trabeculoplasty or PSLT is an advanced tissue-sparing
laser treatment for reducing intraocular pressure. PSLT provides a rapid, precise,
and minimally traumatic (sub-visible) computer-guided treatment that applies a
sequence of patterns onto the trabecular meshwork. Automated rotation of
consecutive patterns ensures that treatment steps are precisely placed around the
trabecular meshwork without overlap or excessive gaps.
When the PSLT pattern is selected, the pattern is delivered when you depress the
footswitch, after which the system automatically rotates the pattern clockwise. If the 360-
degree treatment plan is selected, the pattern rotates a full 360 degrees before treatment
is automatically terminated. If the 180-degree treatment plan is selected, the pattern
rotates 180 degrees before treatment is automatically terminated.
Establish starting location for PSLT pattern.

Align to trabecular meshwork using <Curvature>.
“<Treatment Complete>” displays in the < PSLT Treatment> window, and the system
enters STANDBY mode. Press <

to return to the Anterior Treatment screen.
Additional treatments can be initiated after returning to the Anterior Treatment screen.
