The aim of this prospective randomized study is to investigate the efficacy and safety of trabeculectomy with ologen Collagen Matrix versus trabeculectomy using mitomycin C (MMC) in patients with medically uncontrolled open angle glaucoma.
ologen® Collagen Matrix (CM) is an artificial extracellular matrix (ECM) specifically configured to support repair in connective and epithelial ocular tissue. The device is constructed so as to minimize random growth of fibroblasts and instead to allow them to grow through the pores in the matrix. ologen® CM is a biodegradable scaffold matrix, inducing a regenerative non-scarring wound healing process without using anti-fibrotic agents. For application in glaucoma filtration surgery, ologen® CM is designed to prevent scar formation (subconjunctival and scleral flap scarring is the major risk factor for failure of trabeculectomy). After implanting the ologen® CM on top of the scleral flap in the subconjunctival space, a functional bleb can be created. The aim of the present study is to determine the effectiveness of the ologen® CM and reduce wound scarring, thereby increasing success of trabeculectomy without side effects of MMC. A means of producing better success rate and reduced complications is the purpose of ologen® Collagen Matrix for the aid of glaucoma surgery.

After trabeculectomy, place ologen Collagen Matrix on the top of the scleral flap under the conjunctiva before suturing
After creating a scleral flap, a sponge with Mitomycin-C (0.02%) is applied on the scleral surface for 3 minutes. Afterwards, Mitomycin-C was rinsed out with balanced salt solution.
