RU26411U1 - HOOK LOCK FOR INTRAOCULAR LENS - Google Patents

Abstract

A hook lock for implantation of an intraocular lens, comprising a housing and a working part made in the form of a hook, characterized in that the end of the working part is made in the form of two connected petals facing open parts in the direction opposite to the cornea, designed to be fixed in the hole of the haptic part hook-shaped intraocular lens.

Description

Hook - Intraocular Lens Retainer

The utility model relates to the field of medicine, more specifically to ophthalmology.

A device for fixing an artificial lens of the eye (IHG), used in the method of implantation of IHG with aphakia complicated by the absence of a posterior lens capsule, and described in

RF patent JN 2143872. The device is made in the form of a removable metal (tantalum) antenna, having at one end an open loop for fixing IHG, and at the other end a closed loop for suturing to the sclera.

However, this device has a significant drawback in the difficulty of fixing an open loop with IHG, which can lead to instability of the position of the IHG inside the eye, and the need to suture the other end of the antenna to the sclera can lead to surgical bleeding, leading to a decrease in postoperative visual acuity.

The technical problem solved by the utility model is to achieve a more stable position of IHG, including the iris-lens diaphragm, in the eyes with aphakia and the absence of a capsule bag, including in combination with aniridia, as well as reducing the risk of intraoperative Cro2002109985

incidents associated with trauma to the ciliary zone when hemming the structure to the sclera.

The specified technical problem is solved by the fact that in the hook-retainer of the intraocular lens containing the body and the working part, made in the form of a hook, the end of the working part is made in the form of two connected petals facing the open corners in the direction opposite to the cornea, designed to be fixed in the hole the haptic part of the intraocular lily in the shape of a fishery hook. The entire device can be made of an elastic material with a shape memory, or of polymethyl methacrylate, or of a solid photocurable material, etc.

The utility model is illustrated by the drawings in FIG. 1 and 2. In FIG. 1 shows a general view of the device, where 1 is the housing, 2 is the working part. In Fig.2, the device with the working part 2 is in the eye and the IHG in the form of an iris-lens diaphragm 3 is fixed on the hook.

Work with a hook - a clamp for implanting an intraocular lens is as follows:

After the conjunctival incision, three scleral pockets with 1/3-1 / 2 of the thickness are made with the base to the limb, respectively, the projections of the holes of the haptic part of the irido-lens diaphragm (ICD). Directly behind the vascular network of the limb, a sclera is punctured, through which a hook-clamp is implanted. ICDs are provisionally flashed through the upper hole in the haptic with a 10-0 thread, then folded and inserted into

eye. The hole in the ICD is fixed on a hook in the lower segment with tweezers and a spatula. Then fix the upper holes. The supporting part of the hook is clamped between the layers of the scleral pocket, the pocket is sutured with a 8-0 thread.

Using the utility model proposed by the authors makes it possible to achieve a more stable position of the IHG, including the iridocrystalline diaphragm, in the eyes with aphakia and the absence of a capsule bag, including in combination with aniridia, as well as reduce the risk of intraoperative bleeding associated with trauma to the ciliary zone during hemming to the sclera.
