Abstract

FIELD: medicine, particularly, ophthalmology; applicable in cataract phacoemulsification. SUBSTANCE: device has container for intraocular lens made in form of airtight capsule whose one end is engageable with pusher. Capsule wall is invaginated inside capsule due to which intraocular lens is pushed through open front chamber into capsule bag. EFFECT: reduced time and means consumption due to assembly and soldering of airtight capsule with sterile intraocular lens directly under factory conditions. 2 cl, 3 dwg

Description

 The invention relates to medicine, namely to ophthalmology, and can be used for cataract phacoemulsification.

 A device for implanting an intraocular lens (see patent US N 4573998 A 61 F 2/16, 1986), containing a container for an intraocular lens associated with a pusher. The placement of an intraocular lens in a container before implantation occurs on the operating table. In this case, the lens, the implantation device, including the container for the intraocular lens and the pusher, must be sterile and have the appropriate packaging.

 The present invention allows to solve the problem of implanting an intraocular lens through a small incision, the width of which is determined by the size of the folded intraocular lens. The technical result obtained in this case consists in reducing the time and cost due to the fact that the sealed capsule with a sterile intraocular lens is collected and sealed directly in the factory. This reduces the risk of damage to the intraocular lens during implantation, saves the surgeon during the operation, does not require separate packaging materials for the intraocular lens and container and, accordingly, their sterilization. In the proposed device, the container can be filled with a viscoelastic preparation, which makes it easy to implant an intraocular lens and additionally maintain the depth of the anterior chamber during implantation.

 Separate placement in the capsule of the haptic and optical parts of the intraocular lens for their subsequent implantation allows to further reduce the diameter of the container and, consequently, the width of the surgical section of the eyeball for implantation of the intraocular lens.

 The specified technical result is achieved by the fact that in the device for implantation of an intraocular lens containing a container for an intraocular lens associated with a pusher, the container for an intraocular lens is made in the form of a sealed capsule of elastic material interacting at one end with a pusher, as well as by placement in a capsule the haptic and optical parts of the intraocular lens separately, with the haptic part being located at the exit of the capsule.

The invention is illustrated by drawings, where
FIG. 1 shows a device for implanting an intraocular lens;
FIG. 2 - capsule with an intraocular lens;
FIG. 3 is a variant of a capsule with the haptic and optical parts of an intraocular lens sequentially placed in it.

 A device for implanting an intraocular lens contains a container for an intraocular lens made in the form of a sealed capsule 1 of elastic material. Intraocular lens 2, compressed to the smallest size, is placed in capsule 1. Separate placement of the haptic 3 and optical 4 parts of the intraocular lens in capsule 1 (see Fig. 3) for their subsequent implantation through a small incision in one injection into the eyeball.

 In this case, the haptic part 3 of the intraocular lens 2 is located at the exit of the capsule.

 The capsule 1 is made thin-walled, sealed from one output end 5. The opposite end 6 of the capsule 1 is a tapering cone to facilitate the process of invagination of this end of the capsule 1 inside during implantation.

 Outside, the capsule 1 has a wall thickening 7, which serves to fix the capsule 1 in the holder 8.

 The capsule 1 with the intraocular lens 2 can be filled with a viscoelastic preparation, which makes it easier to implant the intraocular lens 2 and additionally maintain the depth of the anterior chamber during implantation. The conical end 6 of the capsule 1 interacts with the pusher 9.

 A device for implanting an intraocular lens is used as follows.

 Under local anesthesia, cataract is removed by phacoemulsification through a small incision according to the usual method.

 Place the capsule 1 with the intraocular lens 2 in the holder 8, fixing it for the thickening 7 of the wall of the capsule 1. Cut off the sealed end 5 of the capsule 1, which is placed in the capsule bag through the surgical incision. The pusher 9 acts on the opposite conical end 6 of the capsule 1. The wall of the capsule 1 is invaginated inside the capsule 1, due to this, the intraocular lens 2 is pushed out through the opened front chamber into the capsular bag. In order to maintain the depth of the anterior chamber, a viscoelastic preparation is fed into it, filling the capsule space around the intraocular lens 2.

Claims (2)

 1. A device for implanting an intraocular lens containing a container for an intraocular lens associated with a pusher, characterized in that the container for an intraocular lens is made in the form of a sealed factory-sealed capsule of elastic material with one end opened during implantation inserted into the capsule bag, and a cone-shaped other cone that is invaginated inside the capsule by the interaction of the intraocular lens with the pusher through the capsule.  2. The device according to claim 1, characterized in that in the capsule the haptic and optical parts of the intraocular lens are placed separately, and the haptic part is located at the exit of the capsule.
