METHOD OF COMBINED SURGICAL TREATMENT OF PRIMARY OPEN-ANGLE GLAUCOMA Russian patent published in 2019 - IPC A61F9/08 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For the treatment of the primary repeatedly operated open-angle glaucoma of a far-reaching stage, a combined surgical treatment is carried out, including formation of a conjunctival incision, a superficial scleral flap (SSF) with a base to a limb. Before the conjunctival incision is formed, a transscleral CPC is performed by contact-transscleral using a diode laser in a microimpulsive mode with wavelength of 810 nm and exposure of 80 sec, along a circular arc with length 90° in lower hemisphere of eyeball in 3–4 mm from limb, with energy 1,200 mJ, with working cycle 31.3 %, pulse duration 0.5 ms, period 1.1 ms. After the SSF is formed, a deep scleral flap is formed, which is excised together with the external wall of the Schlemm's canal and a strip of corneoscleral tissue, exposing Descemet's membrane with width of 0.5–0.8 mm, Healoflow drainage is introduced, SSF is laid back and the operation is completed by superposition of conjunctival suture.

EFFECT: method enables preserving visual functions, restoring the intraocular fluid outflow pathway and achieving the stable hypotensive effect.
