Intervention / Treatment
Detailed Description
Standard trabeculectomy All trabeculectomy surgeries will be performed under peribulbar anesthesia.Under aseptic surgical technique, superior rectus suture will be placed using 4-0 silk and a fornix-based conjunctival flap will be performed. Sub-Tenon dissection and hemostasis may be performed as required.A half-thickness 4 x 4mm rectangular/ triangular scleral flap will be dissected up to clear cornea, and a 2 × 2 mm deep scleral block will be excised and peripheral iridectomy will be performed. The scleral flap will be closed with one or two 10-0 nylon sutures and conjunctiva will be closed with 8-0 vicryl suture. Releasable sutures may be applied to the scleral flap if needed.
ologen® Collagen Matrix ologen® Collagen Matrix approved by Indian health authority with registration numberof MD-1517 (valid till Mar-15-2018) will be provided by Aeon Ajanta India Pvt. Ltd. free of cost for this clinical research only.
The following table summarizes the model number, shape and manufacturer of ologen® Collagen Matrix to be used in this clinical research.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Intraocular pressure control in the two groups will be compared.
Time Frame: 1 year
|
Comparison of IOP control between the two groups: Assess control of IOP over time.
"Complete success" is defined as IOP reduction of >20% and / or an IOP constantly <21 mmHg without any antiglaucoma medication.
"Qualified success" is defined as IOP < 21 mmHg with topical antiglaucoma medication.
"Failure" is defined as IOP > 21mmHg in 2 subsequent follow visits despite topical antiglaucoma medication.
