Abstract

FIELD: medicine. SUBSTANCE: method involves forming corneal paracentesis. Iris defect border is sutured through the paracentesis along the defect zone boundary. Sclera incision is carried out 4mm far from the limb under thread to 0.5 mm depth. Two canals are built from the middle part of incision into the anterior chamber. Thread ends suturing iris defect border are pulled through the produced canals towards the sclera surface. The thread ends are joined and torn edge of the iris is pulled towards its root. The thread ends are tied in knot and placed into the sclera incision. EFFECT: enhanced effectiveness of anterior chamber repair. 5 dwg

Description

The invention relates to medicine, namely to ophthalmology, and can be used to eliminate defects of the iris, namely the separation of the iris from the root.

A known method for eliminating defects of the iris (see the description of the invention to the patent of the Russian Federation No. 2156613 dated 02/12/1999), including flashing through the corneal paracentesis of the edge of the defect of the iris, removing the ends of the thread from the anterior chamber of the eye and connecting the ends of the thread.

Stitching the edges of the iris in a known manner does not eliminate the defect in the separation of the iris from the root, which ensures the preservation of various disorders in patients: light scattering, photophobia, decreased visual acuity, monocular diplopia, etc. In addition, this affects the restoration of the natural configuration and location of the iris , i.e. on the cosmetic condition of the eye after surgery.

The present invention solves the problem of eliminating the defect of the iris, namely, iridodialysis. The resulting technical result consists in the complete elimination of the defect of the iris. The proposed method anatomically reasonably restores the anatomy of the anterior chamber of the eye. This makes it possible in the future to perform other surgical interventions, for example, cataract extraction, including phacoemulsification through the pupil. The restoration of the iris of the proposed method serves to prevent prolapse of the vitreous body during surgical treatment of cataracts by phacoemulsification. Thus, the claimed method reduces the risk of occurrence and severity of possible postoperative complications

The specified technical result is achieved in that in a method for eliminating iridodialysis, including flashing the thread through paracentesis of the cornea of the edge of the iris defect, removing the ends of the thread from the anterior chamber of the eye and connecting the ends of the thread, the flashing is carried out along the edge of the defect of the iris, on the sclera parallel to the limb in the projection of the natural attachment of the iris an incision is made of the sclera under the thread, from which in the middle part of the iridodialysis two channels are made into the anterior chamber of the eye, from which the ends of the thread are pulled through the channels on a turn the sclera, when connecting the elongated ends of the thread, pull the edge of the iris to its root, and after tying the ends of the thread, they are placed in a scleral incision.

The invention is illustrated by drawings, which depict a phased implementation of the proposed method, namely:

figure 1 - shows the first stage of flashing the thread along the edge of the defect of the iris;

figure 2 - the second stage is an incision of the sclera;

figure 3 - the third stage is the implementation of two channels from an incision of the sclera into the anterior chamber of the eye;

figure 4 - the fourth stage of pulling the ends of the thread through the channels on the surface of the sclera;

figure 5 - the fifth stage - tying the ends of the thread and laying them in a scleral incision.

The method of eliminating iridodialysis is as follows.

After local anesthesia is performed, corneal paracentesis is performed. Through the corneal paracentesis, a long straight atraumatic needle with a thread of polymer 10.0 is used to stitch the edge of the defect of the iris, removing the needle with the thread on the opposite side, and the stitching is carried out along the edge of the defect of the iris. In the projection of the site of natural attachment of the iris, the conjunctiva is opened 4 mm from the limbus and, on the sclera, parallel to the limbus, the sclera is cut under the thread to a depth of 0.5 mm. From the incision of the sclera in the middle part of iridodialysis, two channels are performed 2.0-1.5 mm from the limbus into the anterior chamber of the eye. Micro hooks from the front chamber of the eye through the channels pull the ends of the thread, which sews the edge of the defect of the iris, to the sclera surface. Connecting the elongated ends of the thread, pull the torn edge of the iris to its root. Tie the ends of the thread and lay them in a scleral incision.

Claims (1)

A method for eliminating iridodialysis, including flashing through the corneal paracentesis of the edge of the iris defect, removing the ends of the thread from the anterior chamber of the eye and connecting the ends of the thread, characterized in that the flashing is performed along the edge of the iris defect, on the sclera, in parallel with the limbus, the sclera is incised under the projection of the natural attachment of the iris a thread from which two channels are made in the middle part of iridodialysis into the anterior chamber of the eye, from which the ends of the thread are pulled through the channels onto the surface of the sclera, when connecting utyh ends of the thread pull the edge of the iris to its root, and after tying the ends of the thread stack them into a scleral incision.
