    Purpose.To conduct a comparative assessment of the effectiveness of non-penetrating deep sclerectomy (NPDS) and canaloplasty using a new ophthalmic device Glaustent and Glaucolight system.

    Material and methods. The study included 152 patients (177 eyes) with POAG of 1st, 2nd and 3d stages. The first group consisted of 57 patients (69 eyes), who underwent NPDS. In group II, there were 45 patients (51 eyes) who underwent canaloplasty with the use of Glaucolight device. In group III, 50 people (57 eyes) underwent canaloplasty with the use of newly developed Glaustent device (patent 162 617).

    Results. During canaloplasty in patients of II and III groups in 52.9% (27/51) and 57.8% (33/57) of cases, respectively there was a cloudlike haemorrhage in anterior chamber aqueous humour due to blood reflux. Relative hypotensive effect in patients with initial and developing stages of POAG and by the end of follow-up period equalled 77.7% (28/36) in group I, 83.3% (25/30) in group II, and 84.3% (27/32) in the group III. However, in advanced stages of POAG relative success achieved in group I in 75.7% (25/33) group II and III in 71.4% (15/21) and 72% (18/25) of cases, respectively.

    Conclusion. The developed ophthalmic device for canaloplastyGlaustent has improved catheterization of Schlemm's canal up to 95% (57/60) compared to Glaucolight – 85% (51/60). Canaloplasty for POAG of initial and advanced stages provides the normalization of IOP in 84.3%, whereas in advanced stage of glaucoma the relative hypotensive effect is 72% in the follow-up period up to 3 years.
