Clinical Trial Summary

This study investigates the effects of trabeculectomy and combined phacoemulsification plus trabeculectomy on corneal astigmatism.

The study interventions takes place 6 months after surgery and include examination of refraction, biometry and corneal topography in order to assess the patient's astigmatism. The values are compared to the preoperative baseline values, which are available from patient records.
