Arm Intervention/treatment
study group

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

Post operative:

-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
combined phaco-trabeculectomy surgery

Primary Outcome Measures :
  1. Biometric parameters measured with the AS‑OCT (AC depth (ACD)) after surgery. - anterior chamber depth in mm [ Time Frame: one week post operative ]
    anterior chamber depth in mm Distance from corneal endothelium to anterior surface of the lens

Secondary Outcome Measures :
  1. other biometric parameters measured with the AS‑OCT, [ Time Frame: 1,3,6, month postoperative ]

    Parameter Unit

    Iris thickness μT Iris curvature μC AC width μC Angle opening distance μO Angle recess area μR Trabecular iris angle Degrees Lens vault μV

  2. intra ocular pressure [ Time Frame: 1,3,6, month postoperative ]
    intra ocular pressure in mm hg
