Description

.1  .one

Изобретение относитс  к медицине, в частности к офтальмологии, и может найти применение дл  восстановпенн  зрени  при осложненных глаз.The invention relates to medicine, in particular to ophthalmology, and can be used to restore the vision in patients with complicated eyes.

Известнь кёратопротеэы, предназна- чейные дл  протезировани  роговой оболочки в тех случа х, когда не показана пересадаарогрвицьи Известен кератопротез, который содержит оптическую часть, выполНенкую в виде ступенчатого тела, предртавпщощего собой два. соосных цилиндра разных диаметров, и опорную часть из двух трапециевидных энементов , отход щих от фиксирующего кольца , устанавливаемого на оптической час ти yiji Однако выступание за пределы оптической части фиксирующего кольца и расположени  его вместе с отход щими от него трапециевидными элементами в сло х роговицы приводит к фипь-ррации внутриг пазной жидкости между роговицей и кератопротезом, и отторжением последнего.The limestone keratroproteae, intended for prosthetics of the cornea in those cases when no transplantation is not indicated. A keratoprosthesis is known, which contains an optical part, made in the form of a stepped body, which is pre-shaped with two. coaxial cylinders of different diameters, and the supporting part of two trapezoidal enements extending from the fixing ring, mounted on the optical part yiji. Phytoplasma of intragut fluids between the cornea and keratoprosthesis, and rejection of the latter.

Целыо изобретени   вл етс  исключение фильтрации внутриглазной жидкосТИ между роговицей и кератопротезом и его отторжени . В описываемом кера« топротезе это достигаетс  тем, что в нем опорна  часть выполнена а виде отдельных равноудаленных, от центра и между собой опорных колец, например, трех, соединенных радиальными перемычками с фиксирующим кольцом, установи ленным на цилиндре .меньщего диаметра вплотную к торпу большего диаметра, The purpose of the invention is to exclude filtration of the intraocular fluid between the cornea and the keratoplasty and its rejection. In the described "toprosthesis" kerber, this is achieved by the fact that in it the support part is made as separate equidistant, from the center and between each other, support rings, for example, three, connected by radial bridges with a fixing ring mounted on the cylinder. diameter

0 причем наружный диаметр фиксидгюшего кольца равен диаметру большего цклинд- ра0 and the outer diameter of the fixed ring is equal to the diameter of the larger cylinder

На фиг. 1 изображен описываемый кератопротез, план; на фиг. 2 - разрез FIG. 1 depicts the described keratoprosthesis, plan; in fig. 2 - section

5 по А-А на фиг. 1.5 according to A-A in FIG. one.
