They will be subjected to:
Preoperative A-complete ophthalmic examination will be done for every patient; B- Biometric parameters measured with the AS‑OCT C- Medical fitness for all patients D- Informed consent will be obtained from all patients after through explanation of operation and its potential benefits and risks.
Surgery combined Phaco trabeculectomy
-Follow-up examinations will be performed for every patient at 1day, 1 week, 1 and 3 months postoperatively.
and biometric parameters measured with the AS‑OCT before and after the surgery will be used to collect the data.
-The data will be managed and analysed with confidentiality by scientifically qualified persons
Procedure: phaco- trabeculectomy
