<p class="p1"><span class="s1"><strong>Aim. </strong>To analyze the efficacy of modified non-penetrating deep sclerectomy. </span></p><p class="p1"><span class="s1"><strong>Materials and methods. </strong>POAG patients enrolled in the study were divided into 2 groups: study group included 29 patients who were referred for modified non-penetrating deep sclerectomy, control group included 33 patients who were referred for standard non-penetrating deep sclerectomy. IOP level was 31.9±3.2 mm Hg in the study group and 31.5±3.3 mm Hg in the control group. Modification of non-penetrating deep sclerectomy consists in the separation of fornix-based Ushaped scleral flap, Schlemm’s canal opening, scleral tunnel creation and its dilation with polyamide 5/0 suture. </span></p><p class="p1"><span class="s1"><strong>Results. </strong>Three weeks after surgery, moderate hypotension was observed in both groups (15.7±1.56 mm Hg in the study group and 16.9±1.9 in the control group). Three months after surgery, IOP level was 17.47±1.24 mm Hg in the study group and 18.74±1.37 in the control group. Ten months after surgery, IOP level in the study group was significantly lower than in the control group (19.14±1.27 mm Hg and 21.31±1.42 mm Hg, respectively, р&lt;0.05). </span></p><p class="p1"><span class="s1"><strong>Conclusions. </strong>The proposed surgical technique provides stable and long-term hypotensive effect and prevents excessive scarring in filtering area. Suture inserted into the scleral tunnel dilates it and provides continuous aqueous humor outflow. </span></p>
