SLT Clinical Procedure and Parameters 103
Selecta
PBL200051, Rev J
SLT Contraindications for Use
The Selecta is contraindicated in patients with neovascular glaucoma and
angle closure glaucoma.
SLT Complications and Adverse Events
In a clinical study sponsored by Lumenis (formerly Coherent Medical Group),
patients who received selective laser trabeculoplasty treatment experienced
some complications and adverse events which were considered to be related to
the treatment, including mild transient anterior chamber inflammation in
many patients, IOP increase of 10mm Hg, conjunctivitis, and eye pain. A
number of other complications occurred at an incidence of less than 1%,
including blurred vision, iritis, corneal edema, corneal lesion, and headache.
Although not considered treatment-related, another potential complication of
laser trabeculoplasty is the formation of peripheral anterior synechiae.
SLT Precautions
The following precautions are suggested when using the Selecta for SLT:
• To reduce the risk of damage to non-targeted tissues, the treatment
energy setting should be the minimum energy necessary to perform
the treatment. Caution should be exercised when using pulse
energies exceeding 1.4 mJ.
• Caution should be exercised during treatment if blood vessels are
present in the angle.
• Treatment of blood vessels in the vicinity of the trabecular
meshwork should be avoided due to the risk of hemorrhage.
• Caution should be exercised when treating patients with pre-
existing anterior chamber inflammation including uveitis, since the
procedure itself may induce a mild anterior chamber inflammatory
response.
• Ocular surgery should be performed only when the structures to be
treated can be visualized clearly.
