Description

ARTIFICIAL EYE CRYSTAL

The utility model relates to medicine, namely to ophthalmology and can be used for surgical treatment of cataracts.

The artificial lens of the eye (IHG) is known, consisting of the optical part and support elements in the form of closed loops located at an angle of 120 degrees to each other and located in the plane of the parallel optical part and 0.5 mm away from it (Fedorov S.N. - Implantation of an artificial lens. Publisher Medicine 1977, p. 54-56).

Due to the fact that the aforementioned IHG is fixed to the pupil edge of the iris, it has the following disadvantages:

- the difficulty of implantation with a wide pupil;

-the need for additional fixation of the IHG to the iris with sutures;

-constant trauma to the iris. The objective of the proposed model is to create

IHG, more reliably and simply fixed in the eye.

The technical result is achieved by the fact that the artificial lens of the eye, containing the optical part and three supporting elements in the form of closed loops located at an angle of 120 degrees to each other, according to

MKY A61f2 / 16

utility model, each supporting element contains hinges of the first kind, with each hinge located in the plane of its loop and on its top. In this case, the supporting elements can be in the plane of the optical part or bent anteriorly from it. The supporting elements in the plane of the optical part are located relative to each other at an angle of 120 degrees. If the supporting elements are bent, then their projections into the plane of the optical part are located at an angle of 120 degrees to each other.

The proposed IHG is illustrated in Fig.1-2, the IHG consists of an optical part 1 and of three closed support elements 2 in the form of loops. Each loop has in its plane a hinge of the first kind 3. Moreover, the hinges 3 are located on the tops of the loops of the supporting elements 2.

Due to the fact that capsulorexis (unlike the pupil) does not change its size, IHG is more reliably fixed in the eye. This reduces the risk of mixing IHG in the postoperative period, eliminates trauma to the iris, avoids the procedure for additional fixation of IHG with sutures, and reduces the time of surgical intervention, i.e. simplifies the implantation procedure and facilitates the work of the surgeon, which is especially important in the absence of the posterior capsule.

Implantation is carried out as follows:

Under local anesthesia, a surgical incision is formed and, after circular capsulorexis of the anterior lens capsule, size b-7mm, cataract is removed. Further, in the cavity of the eye, in the area of capsulorexis, IHG is introduced and attached with its supporting elements to the edge of capsulorexis. The operation is completed by sealing the surgical wound and the introduction of an antibiotic under the conjunctiva.

Example:

Patient B. 65 years. Visual acuity of the right eye is 0.01, Ophthalmometry is 41.0 D. The length of the eye is 24.0 mm. Intraocular pressure 20 mmHg Field of View - Diagnosis: Age-related cataract of the right eye.

The patient underwent cataract phacoemulsification with implantation of IHG in accordance with the proposed utility model.
