The Effect of Selective Laser Trabeculoplasty (SLT) on Ocular Rigidity
The purpose of this study is to examine the influence of selective laser trabeculoplasty (SLT) on ocular rigidity in glaucoma patients.

Ocular Rigidity (corneal hysteresis and corneal resistance factor) is measured with the Ocular Response Analyzer (Reichert) before and 4 weeks after SLT (Q-switched 532 nm frequency doubled neodymium yttrium aluminium garnet laser with a spot size of 400 µm and a 3-ns pulse duration). The trabecular meshwork is treated with 100 spots over 360° and an energy of 0,8 mJ.

The purpose is to examine if selective laser trabeculoplasty changes ocular rigidity.

Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
Glaucoma
Procedure: Selective Laser Trabeculoplasty
100 spots with an energy of 0,8 mJ are applied over 360° of the trabecular meshwork of glaucoma patients with a Q-switched 532 nm frequency doubled neodymium YAG Laser.
Other Names:
  • SLT
  • ORA
glaucoma patients
All of the patients treated with SLT need further IOP reduction for control of their glaucoma.
