[Long-Term Results after Trabeculectomy Combined with Mitomycin C and Ologen Implant].

BACKGROUND

The Ologen implant consists of a biodegradable collagen and glycosaminoglycan and is intended to avoid postoperative bleb scarring or encapsulation.

MATERIALS AND

METHODS

In a retrospective clinical study, 806 patients with advanced glaucoma were treated with trabeculectomy combined with mitomycin C0.02% and Ologen implant. The follow-up time of the study was 8 years.

RESULTS

A long-term reduction of the intraocular pressure below 16 mmHg was achieved in 92.6% of the patients without glaucoma eye drops in the long-term observation period. The rate of complication was very low during the postoperative period and additional surgical procedures for over-filtration with subsequent choroidal detachment were seen in 6.8% of the patients. A failure of the combined operation with phacoemulsification and implantation of an intraocular lens resulted in revision of the bleb or the application of compressive sutures in 3.35% of patients within 8 years.

CONCLUSION

The Ologen implant was introduced in glaucoma surgery to increase the effectiveness of trabeculectomy and to reduce the complications. Trabeculectomy combined with mitomycin C0.02% and an Ologen implant provides a satisfactory filtering effect without the undesirable effects of postoperative fibrosis.
