FIELD: medicine, ophthalmology.
SUBSTANCE: conjunctival incision and the formation of a superficial scleral flap (SSF) is performed. First, paracentesis is performed at 9 o’clock position, 0.2–0.3 ml of viscoelastic is injected into the anterior chamber, a paralimbal conjunctival incision 4 mm long is formed in the projection of the implanted MN. Coagulate episcleral vessels, form SSF along the contour of the previous one, size 3×3 mm, base to the limbus, one third of the thickness of the sclera, 0.2–0.3 ml of viscoelastic is injected into the anterior chamber through paracentesis. The iris is separated from the MS spur located on its distal part with a spatula through paracentesis, the IOL is rotated by 90 degrees behind the proximal part of the MS with a hook to rotate the IOL and removed from the anterior chamber. A fragment of the iris, inserted into the hole formed after the removal of the MS, is excised with Vannas scissors. Next, a deep scleral flap (DSF) of a triangular shape is cut out with exposure of the flat part of the ciliary body to the circular ligament, after which the DSF is excised. SSF is fixed on the sides with two interrupted sutures, a continuous suture is applied to the conjunctiva, 0.2 ml of viscoelastic is injected into the anterior chamber through paracentesis.
EFFECT: method makes it possible to remove the mini-shunt Express model P-50, to achieve stable compensation of ophthalmotonus, to preserve the surgically formed intraocular fluid outflow tracts, and to reduce the frequency of postoperative complications.
