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

结局指标
主要结局
Change in ocular cylinder and axis untill 6 months after trabeculectomy.
时间窗: pre-operative until 6 months post-operative
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.
