Official Title: The Effect of Selective Laser Trabeculoplasty (SLT) on Ocular Rigidity

Brief Summary: The purpose of this study is to examine the influence of selective laser trabeculoplasty (SLT) on ocular rigidity in glaucoma patients.

Detailed Summary:

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.

Current Primary Outcome: change in ocular rigidity [ Time Frame: 4 weeks ]

Is there a change in ocular rigidity (corneal hysteresis, corneal resistance factor) as measured with the Ocular Response Analyzer (Reichert) after selective laser trabeculoplasty?


Original Primary Outcome: change in ocular rigidity [ Time Frame: 4 weeks ]

Is there a change in ocular rigidtiy (corneal hysteresis, corneal resistance factor) as measured with the Ocular Response Analyzer (Reichert) after selective laser trebeculoplasty?


Current Secondary Outcome: IOP reduction [ Time Frame: 4 weeks ]

Is there an effective IOP drop after SLT?


Original Secondary Outcome: Same as current
