The invention relates to medicine, in particular to ophthalmology. Before implantation of the lens in the capsular bag in his equator install elastic ring, made in the form of a torus with a circular groove on the inner diameter, having an external diameter corresponding to the diameter of the capsular bag. Implanted artificial lens of the eye, placing the haptic elements in a groove on the inner surface of the elastic ring.

The invention relates to medicine, namely to ophthalmology, and can be used for the surgical treatment of cataract extracapsular method.

There is a method of implanting an artificial lens in violation of the integrity of the posterior capsule, involving suture fixation of the lens to the sclera (Regillo C, Tidwell J. A small-incision technique for suturing a posterior chamber intraocular lens// Ophthalmic Surg. - 1996. - Vol. 27. - N-6. - P. 473-475). This method is quite effective, as it provides a stable capsule small, these manipulations seem overly traumatic, because carry increased risk of complications (bleeding, trauma to the corneal endothelium, the detachment of the choroid and others).

The task of the invention is to develop a safe and effective method of implanting an artificial lens in violation of the integrity of the posterior capsule, not exceeding a length of 2/3 of its circumference.

The technical result that is achievable with the use of the invention is the reduction in the number of operative and postoperative complications due to the introduction in the capsular bag in his equator elastic ring having an outer diameter corresponding to the diameter of the capsular bag.

A distinctive feature of the method is that the ring is made in the form of a torus with a circular groove on the inner diameter. The specified groove serves for fixing the textural elements of the artificial eye lens. This creates conditions for the fixation and stabilization of the lens in the capsular bag. In addition, the elastic ring prevents the increase of the defect capsules during implantation of an artificial lens in the eye.

The method implemented is placed nucleus of the crystalline lens during leaching lenticular masses detect the defect capsular bag. Lenticular masses are evacuated using the Simcoe cannula after filling the anterior chamber with viscoelastic. Through an incision injected elastic ring and install in the capsular bag along its equator. Implanted artificial lens of the eye, placing the haptic elements in a groove on the inner surface of the elastic ring. Viscoelastic aspirinum, surgical wound is sealed seams. The surgery is completed by the introduction of a solution of the antibiotic and corticosteroid subkonyunktivalno.

The method of implantation elastic ring is illustrated in the drawings, where Fig. 1 shows the ring 1 with a groove on the inner edge 2; Fig. 2 - ring 1, installed in the capsule of the natural lens, an artificial eye lens 3 and the defect capsular bag 4.

The progress of the operation.

After local anesthesia and akinesia of the eyeball 2% R-rum lidocaine put vekorasshiriteli and recorded on the seam-taped top straight muscle. Spent the incision of the cornea with a diamond blade. In front of the camera introduced a solution mezatona of 0.1% - 0.1 ml and viscoelastic (Vision). The anterior capsule is opened by cystotomy. Removed the nucleus of the crystalline lens by the method of hydraexpress. At the stage of laundering lenticular masses discovered a defect in the posterior capsule of the crystalline lens length 2.5-3.0 mm for 5 hours. Anterior chamber and capsular bag was filled with viscoelastic, the remains of lenticular masses removed the "dry" method using a Simcoe cannula. In the capsular bag was introduced elastic ring, placing it on the equator. Again filled the front camera viscoelastic and implanted posterior chamber IOL models T-28, placing the haptic elements of the lens in the groove on the inner side of the elastic ring. The operative wound was sealed seams. The operation was completed by the introduction of solutions decasone and kanamycin subkonyunktivalno.

Visual acuity without correction after 1 week after surgery was equal to 0.6. Ophthalmometry: 0 deg. - 41,50 diopters; 90 deg. - 43,75 diopters. Intraocular pressure is 15 mm RT.art., field tranlastion ring used in 17 patients (18 eyes). In any case, was not increasing defect capsular bag IOL decentration and did not identify specific complications.

Implementation of the proposed method can significantly reduce the number of operative and postoperative complications and hasten the visual and social rehabilitation of patients.

SUBSTANCE: method involves introducing 0.1-0.3 ml of photosensitizing gel preliminarily activated with laser radiation, after having removed neovascular membrane. The photosensitizing gel is based on a viscoelastic of hyaluronic acid containing khlorin, selected from group containing photolon, radachlorine or photoditazine in the amount of 0.1-2% by mass. The photosensitizing gel is in vitro activated with laser radiation having wavelength of 661-666 nm during 3-10 min with total radiation dose being equal to 100-600 J/cm2. The gel is introduced immediately after being activated. To compress the retina, vitreous cavity is filled with perfluororganic compound or air to be further substituted with silicon oil. The operation is ended with placing sutures on sclerotomy and conjunctiva areas. Compounds like chealon, viscoate or hyatulon are used as viscoelastic based on hyaluronic acid. Perfluormetylcyclohexylperidin, perfluortributylamine or perfluorpolyester or like are used as the perfluororganic compound for filling vitreous cavity.

EFFECT: excluded recurrences of surgically removed neovascular membrane and development of proliferative retinopathy and retina detachment; retained vision function.
