METHOD OF CIRCULAR EXTRASCLERAL FILLING WITH DRAINAGE OF SUBRETINAL FLUID Russian patent published in 2023 - IPC A61F9/07 A61F9/08 

FIELD: medicine; ophthalmic surgery.

SUBSTANCE: limbal peritomy of the conjunctiva is performed, the conjunctiva and Tenon's capsule are shifted posteriorly, and the four rectus muscles are released. Ligatures are applied under the rectus muscles, and the filling is fixed using U-shaped mattress sutures to the sclera in four opposite sectors. Subretinal fluid (SRF) is drained in the area of greatest height of the detached retina. Then the scleral incision is sutured with a single interrupted suture, and the edges of the filling are sutured together with a mattress suture. The conjunctiva is pulled over the filling to the limbus, applying interrupted sutures. The length of the filling is calculated in advance using a computer program, taking into account the size of the anterior-posterior axis of the eye or the equatorial diameter of the eyeball. Then the calculated length of the filling is measured on the tape using a ruler and marked with a surgical marker. After that, the tape is crossed with scissors 1 cm longer than the intended and calculated length of the filling, and drainage of the SRZ is performed non-contactly using the endolaser probe of the microsurgical system. In a particular case, non-contact laser puncture of the choroid is performed using an endolaser probe of a microsurgical system, starting with preliminary coagulation of vessels with a laser exposure of 100 mW and an exposure of 120 ms, and then when performing the puncture, the radiation power is increased to 120 mW, an exposure should be 100 ms. The edges of the filling are joined and stitched end to end.

EFFECT: method allows to perform surgical intervention through the use of a precisely selected filling and the use of non-contact choroidal puncture.
