Description

II

Изобретение относитс  к медицинской технике и может быть использовано в офтальмологии дл  аллопластики хрусталика глаза при операци х по поводу катаракты.The invention relates to medical technology and can be used in ophthalmology for alloplasty of the lens of the eye during cataract surgery.

Известна ирис-линза, содерл аща  линзу и две опорные ножки из благородных металлов; одна ножка - скольз ща  - вводитс  в отверстие у основани  в радужной оболочке на 6-ти часах, друга  ножка подшиваетс  к радужной оболочке у ее основани  на 12-ти часах 1.The famous iris lens contains a lens and two supporting legs made of noble metals; one leg — sliding — is inserted into the hole at the base in the iris at 6 o'clock, the other leg is stitched to the iris at its base at 12 o'clock 1.

Однако сложно выполн ть имплантацию, св занную с фиксацией искусственного хрусталика к радужной оболочке. Необходимо проводить разрезы в ней дл  проведени  через них опорных элементов линзы, наложены дополнительные швы на радужку дл  их укреплени . Механическа  травма эндотели  радужки, вызываема  фиксацией линзы на ее наружной поверхности, и возможна  травма эндотели  роговицы, вызываема  необходимостью манипулировани  в передней камере глаза.However, it is difficult to perform implantation associated with the fixation of an artificial lens to the iris. It is necessary to make incisions in it to pass through them the supporting elements of the lens, additional stitches are put on the iris to strengthen them. Mechanical injury to the endothelium of the iris caused by fixing the lens on its outer surface, and possible injury to the endothelium of the cornea caused by the need to manipulate in the anterior chamber of the eye.

Известна ирис-клипс-линза, содержаща  линзу с прикрепленными к ней на наружной ее поверхности трем  дужками и трем  антенками , закрепленными в боковой части линзы , все это обеспечивает фиксирование хрусталика в зрачке радужной оболочки 2. The famous iris-clip-lens, containing a lens with three arcs attached to it on its outer surface and three antennae attached to the side of the lens, all this ensures the fixation of the lens in the pupil of the iris 2.

Недостатками ирис-клипс-линзы  вл ютс  механическа  травма эндотели  и пигментного эпители  радужной оболочки при введении ее в зону зрачка, ограниченна  возможность 3асщирени  и сужени  зрачка радужной оболочки, что создает серьезные трудности в лечении послеоперационных придоциклитов , вызывает снижение остроты зрени  в услови х пониженного освещени , а главное, возможность дислокации линзы в переднюю камеру и необходимость повторного оперативного вмешательства.The disadvantages of iris-clip-lenses are the mechanical trauma of the endothelium and the pigment epithelium of the iris when introduced into the pupil area, the limited possibility of dilation and contraction of the iris of the iris, which creates serious difficulties in the treatment of postoperative podocyclitis, reduces visual acuity in low light and, most importantly, the possibility of dislocation of the lens in the anterior chamber and the need for repeated surgical intervention.

Известен искусственный хрусталик дл  интеркапсул рной имплантации, содержащий линзу и опорный элемент, закрепленный в линзе. Опорна  часть его вьшолнена в виде двух петлеобразных лапок, одна из которых имеет два выступа 3.An artificial lens for intercapsular implantation is known, comprising a lens and a support member secured in the lens. The supporting part of it is made in the form of two loop-shaped legs, one of which has two projections 3.

Недостатками искусственного хрусталика  вл етс  необходимость фиксации опорных элементов искусственного хрусталика щвами к радужной оболочке, проведение широкого разреза в ней (травмирует ее дил The disadvantages of an artificial lens is the need to fix the supporting elements of the artificial lens with pits to the iris, making a wide cut in it (traumatizing it
