METHOD FOR IMPLANTING AN ORBITAL SPHERICAL IMPLANT AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC A61F9/07 A61F2/14 

FIELD: medicine.

SUBSTANCE: inventions group relates to medicine, namely to ophthalmology. The diameter of the orbital spherical implant is determined preoperatively. Then enucleation is performed, the implant is immersed into the orbit. Next, the device is installed with a concave surface to the implant. Then, exophthalmometry is performed, while focusing on the protrusion on the front surface of the device, the level of protrusion of the device relative to the fellow eye is determined. Next, the implant is moved either posteriorly or anteriorly until a level of symmetry with the fellow eye is reached, after which the device is removed. Then two opposite extraocular rectus muscles are fixed to the surface of the implant or to the material in which the implant is wrapped. Next, the device is re-installed, then repeated exophthalmometry is performed to determine the level of protrusion of the device, with the implant moving either posteriorly or anteriorly until a level of symmetry with the fellow eye is reached. Next, the remaining two rectus muscles are fixed to the implant, and the device is reinstalled. Then, exophthalmometry is performed to determine the level of protrusion, and if the level is different, the two muscles that are fixed last are released, and the position of the implant is corrected. The specified sequence of actions with the installation and removal of the device, as well as with fixation and unfixation of the two muscles, fixed last, is repeated until the device is symmetrical in relation to the fellow eye, at the end of the operation, the conjunctiva and Tenon's membrane are sutured in layers. This method is carried out using the original device.

EFFECT: inventions group makes it possible to ensure the immersion of the implant to the required depth, the achievement of symmetry in the standing of the paired eyeball and the external prosthesis, and to reduce the severity of the anophthalmic syndrome.
