METHOD FOR SURGICAL MANAGEMENT OF GLAUCOMA Russian patent published in 2014 - IPC A61F9/08 

FIELD: medicine.

SUBSTANCE: conjunctiva is incised. A rectangular superficial sclera flap is separated by 1/3 of a corneal thickness with its base to a limb until reaching transparent layers of a corneal stroma. A deep scleral flap is separated until reaching a scleral spur. The deep scleral flap is excised with an outer wall of a Shlemm's canal. Separating all the scleral flaps, excising the deep scleral flap with the outer wall of the Schlemm's canal and exposing a trabecule and a Descemet's membrane are performed with the use of an ultraviolet laser with a flat-section beam supplied to a surgical site by means of a light guide. A wave length is 308 nm, a pulse length is 10-20 ns, a frequency is 2-20 Hz, a power density is 300-800 mJ/cm², a focal diameter is 0.2-1 mm.

EFFECT: method enables reducing the invasiveness and increasing the antihypertensive effect of the surgery by performing graduated and uniform incisions and scleral tissue separation, trabecule and Descemet's membrane ablation, reducing a risk of eye perforation and complications associated with inflammation and cicatrisation.
