Abstract

1459581 Corneal prostheses MOSKOV MEDITSIN STOMATOLOGIOHE INST 4 March 1974 [4 March 1973] 9672/74 Heading A5R A through-corneal prosthesis comprises a support 1 in the form of a ring 2, Fig. 2, hav ing two diametrically opposed frames 3 thereon, a bush 4, Fig. 5, with a threaded hole rigidly mounted in the support, a threaded, temporary, removable plug (6) Fig. 4, (not Shown), for closing said hole, and a threaded, removable, generally cylindrical transparent member 5 which is screwed into the bush to replace said plug after implantation of the support in the cornea 7, the height of the plug and of the bush each being in the range 0.25 mm and 0.5 mm, whereby the support member and plug can be implanted without perforating the inner corneal layers 9.

Description

Изобретение относитс  к области офтальмологии. Известен протез роговицы, содер жащий опорную часть в виде диска с отверсти ми, оптический цилиндр и вкпадьш. Однако больша  толщина и площаДь .опорной части, а также необходимость перфорации передних или задних слоев роговищ при Введении протеза в первом этапе операции привод т в р де случаев Ц его отторжению. Следствием этого  вл ютс  больша  травматичность on рации, значительное разобщение сло ев роговицы опорной частью и воэНожность подтекани  жидкости глаза через отверстие в роговице после первого этапа. Цель изобретени  - предупрежде ,ние отторжени  протеза. Это достигаетс  тем, что опор на  часть выполнена в виде кольца рамками, причем толщина втулки и В1сладыша не превьпиает толщины роговицы . . 4г На фиг. 1 показан предлагаемый протез в собранном виде; на фиг. 2 положение протеза после первого этапа операции; на фиг. 3 - положение протеза после второго этапа операции. Протез роговицы содержит опорную часть, выполненную в виде кольца 1 с диаметрально расположенными рамками 2 и 3, втулку 4 с внутренней резьбой, на которой жестко закреплена опорна  часть, оптический цилиндр 5 и вкладьщ 6. При проведении-операции па повоДУ т желого бельма роговицы 7 после ее расслоени  опорна  часть с ввинченным во втулку 4 временным вкладьшем 6 вводитс  между сло ми. После наложени  щва заканчиваетс  первый этап операции. Через 4 мес ца производитс  перфораци  передних слоев 8 роговицы 7, расположенньгх над вкладьппем 6. Временный вкладьш удал етс  и перфорируютс  задние слои 9 роговицы. После этого ввинчиваетс  оптический цилиндр 5 и операци  заканчиваетс .This invention relates to the field of ophthalmology. A cornea prosthesis is known, which includes a disc-shaped support part with holes, an optical cylinder, and a hatch. However, the large thickness and area of the support part, as well as the need for perforation of the anterior or posterior layers of the cornea during the insertion of the prosthesis in the first stage of the operation, in a number of cases, C cause it to be rejected. The result is a large invasiveness, a significant separation of the corneal layers by the anvil, and the leakage of eye fluid through the hole in the cornea after the first stage. The purpose of the invention is to prevent the prosthesis from being rejected. This is achieved in that the support on the part is made in the form of a ring with frames, and the thickness of the sleeve and the B1 sweet does not exceed the thickness of the cornea. . 4g. In FIG. 1 shows the proposed prosthesis assembled; in fig. 2 position of the prosthesis after the first stage of the operation; in fig. 3 - position of the prosthesis after the second stage of the operation. The cornea prosthesis contains a support part made in the form of a ring 1 with diametrically located frames 2 and 3, a sleeve 4 with an internal thread on which the support part is rigidly fixed, an optical cylinder 5 and an insert 6. When performing an operation on a heavy corneal abalone 7 after its separation, the support part with the temporary insert 6 screwed into the sleeve 4 is inserted between the layers. After applying the joint, the first stage of the operation ends. After 4 months, the anterior layers of the cornea 7 are perforated, located above the insert 6. The temporary insert is removed and the posterior layers of the cornea 9 are perforated. Thereafter, the optical cylinder 5 is screwed in and the operation is completed.
