ologen® Collagen Matrix (ologen® CM) is an advanced wound care device composed of a porous matrix of cross-linked atelocollagen and glycosaminoglycan. ologen® Collagen Matrix is specifically designed to promote scar-less wound healing in a wide range of ophthalmic surgeries, such as to create a prominent healthy vascular bleb in glaucoma surgery.

  • Dry form scaffold




Features to successful bleb formation

The biomechanical properties of ologen® Collagen Matrix facilitates bleb formation while providing resistance at the outlet of the scleral tunnel to prevent hypotony.

ologen® Collagen Matrix may be a safe & effective alternative to MMC

The two-year complete success with ologen® Collagen Matrix (defined as IOP ≤ 15 mmHg without medication) was 50% compared to 40% for the MMC group. Log-rank test shows ologen® Collagen Matrix to be comparable as MMC in complete success ≤ 15 mmHg IOP (p>0.05).
