Abstract

This invention relates to the field of medicine, namely ophthalmology. The goal is to preserve the natural configuration of the scleral sheath. A scleral graft is prepared by dissecting the cornea, removing the contents of the eye, treating with disinfectants and drying, and after processing, a rubber balloon is introduced into the scleral slope and filled with molten paraffin and giving the sclera a natural shape.

Description

The invention relates to medicine, namely ophthalmology.

The purpose of the invention is to preserve the natural configuration of the scleral sheath.

The method is carried out as follows.

EXAMPLE 1. A cadaveric eye, taken no later than 24 hours after death, is washed in a 1: 1000 sublimate solution, then in an antibiotic solution, freed from the remnants of conjunctiva, adipose tissue, tenon capsule and muscle tendons, and the cornea is excised. with a sclera border 1-2 mm wide, the contents of the eye are removed. The scleral shell is again washed with antibiotics in a solution, dried with gauze napkins, straightened, a thin-walled rubber balloon is inserted into its cavity, and molten paraffin is poured into it. Spray End

the paraffin is compressed, advancing under pressure into the sclera cavity, the sclera is easily expanded, acquiring a natural configuration, which is preserved during the paraffin hardening process. The sclera on a paraffin bead is placed in a desiccator with silica gel for drying. After 24 hours, a figural graft is cut out directly on a paraffin bead from a dried sclera with a scalpel to strengthen the sclera to a patient with progressive myopia. The graft obtained after cutting maintains the natural curvature of the eye.

Example 2: After treatment with enucleated cadaver eyes after treatment with mercuric chloride 1: 1000 and monomitsin solutions (1.0 g per 10 ml of 0.9% sodium chloride solution), the cornea with a sclera border 1-2 mm wide is excised, its contents are removed, the scleral cavity is washed with a solution of monomitsio

They are dried with a gauze tampon, a thin-walled rubber can is inserted into it, having a funnel-like shape with a spherical expansion at the end with a diameter of 23-25 mm, which is filled with melted paraffin. The sclera at the same time straightens to its natural shape. In order to preserve the natural shape of the scleral shell, the paraffin during the freezing process compresses within 2-3 minutes. The sclera on a paraffin bead is placed in a desiccator with silica gel for 24 hours, then transferred to a tube with a small amount of silica gel, the lid is sealed with molten paraffin. The sclera in the bottle is stored at room temperature for 6 months. Before the operation, 4 grafts with a length of 20 mm and a width of 9 mm are cut out of the sclera on a paraffin ball with a razor blade, and in them they are made with trepan 1 mm in diameter and have multiple perforations. Transplants have a natural curvature of the eye. They are used to strengthen the sclera in a patient with progressive myopia.

The proposed method allows to preserve its natural configuration. The paraffin frozen in the sclera cavity serves as a good support in the process of cutting out grafts of different shape and size, which have a natural curvature of the eye block, on it. The grafts with generic properties are easily laid on the sclera of the recipient at the time of the operation, tight to it, which speeds up the engraftment process. Drying the sclera on a paraffin ball provides scleral grafts with a natural curvature of the eye.

DETAILED DESCRIPTION A method for preparing an eye sclera for transplantation by cutting a cornea, removing the contents of the eye, processing with disinfectants and drying, characterized in that, in order to preserve the natural configuration of the scleral shell, after treatment, a rubber balloon is introduced into the scleral cavity and filled with molten paraffin and as it solidifies, it gives the sclera a natural shape.
