Astigmatism Post-trabeculectomy

Universitaire Ziekenhuizen KU Leuven52 enrolled

Overview

The aim of this project: 1. Confirming the modification in corneal astigmatism after trabeculectomy with MMC and intracameral administration of bevacizumab. 2. Medium-term follow up (6 months) of the induced corneal astigmatism. 3. Investigating correlations between postoperative astigmatism, particularly with the postoperative IOP.

Outcomes

Primary Outcomes

Change in ocular cylinder and axis untill 6 months after trabeculectomy.

Comparing the change in corneal cylinder, axis and IOP before the operation and 1,3 and 6 months after the operation. We will compare these vectors by vector analyses.

Time frame: pre-operative until 6 months post-operative
