<p>Canaloplasty in the Treatment of Primary Open-Angle Glaucoma: Patient Selection and Perspectives</p>

Mini-canaloplasty as a modified technique for the surgical treatment of open-angle glaucoma

“…In the first stage of the procedure, the ocular conjunctiva was cut off from the limbus, and the vascular bed of the episclera was scraped off over an area of approximately 5 mm 2 . In the next stage, two parallel cuts of the sclera were performed, one in the limbus and the other 2 mm from the limbus, enabling dissection of a 4 × 1.5 mm superficial flap of a thickness corresponding to one-third of the sclera without cutting away one of the flap's side walls 27 (Fig. 1).…”

“…A 1.0 × 1.0 mm scleral block with a pedicle from the side of the cornea was cut out under the flap, directly above the SC. The perpendicular cuts in the sclera revealed the scleral spur, inlets into SC, and a small area of the TDM 27 (Figs. 2, 3).…”

“…Insertion of the catheter through a 1.0 × 1.0 mm window required its tip to be levered by means of an additional instrument. In our case, we used a micro-hook 27 (Fig. 4).…”

“…After the suture was cut away from the catheter, a loop was made to control the suture's tension in the canal. The loop was tightened until the curvature of the corneal limbus was moulded 27 (Fig. 5).…”

“…The window was closed with the scleral block and loosely covered with the superficial scleral flap. The conjunctiva was closed via bipolar diathermy at the end of the procedure 27 (Fig. 6, Supplementary Video S1).…”
