DESCRIPTION
SUTURELESS SCLERAL FIXATION LENS
Related Technical Field:
This invention is related to sutureless scleral fixation lens which is designed to be used in sutureless scleral lens fixation operations and which has a special haptical form. Prior Art:
Eye lenses are the tissues with the highest diffraction in the eye after cornea (transparent layer at the outermost part of the eye) . By the virtue of this diffraction, the light rays are focused onto the retina located at the rear part of the eye and thus, vision is provided. Loss of transparency of the eye lenses due to various reasons is called cataract and the absence of the eye lenses is called aphakia. Aphakia decreases diffraction in the eye which causes diffraction error. Aphakia is treated by placing an artificial intra ocular lens (IOL) into the eye.
Artificial intraocular lenses are generally composed of two parts which are;
1) Optical part (the lens part which provides vision)
2) Haptic part (the part for fixing the lens into the eye) .
During the cataract operation, the capsule of the natural lens is opened and the lens is taken out. If there is no problem with the integrity of the lens capsule and the zonula which binds lens capsule to the sclera, the surgent tries to place the artificial intraocular lens into the capsule which is the normal physiological location of said lens. However, in some cases, the integrity of the capsule and the zonula is not enough and in order to fix the intraocular lens into the eye, it is needed to place it to different regions. In this case, the artificial intraocular lens may be placed into the anterior chamber, namely between the cornea and the iris (the colored part of the eye which is formed by a thin, contracting membrane present between the cornea and the eye lens) , into the gap between the iris and the lens called sulcus. In addition to this, the lens may also be fixed to the iris or sclera (opaque, dense fatty tissue which forms the 5/6 of the back part of the eye ball except the cornea at the anterior) . Instead of its normal location, attaching the artificial intraocular lens onto the iris or placing it into the anterior chamber or sulcus cause various complications. Therefore, in order to place the lens into its normal position, an operation is done to fix the lens to the sclera.
The scleral fixation technique used in intraocular lens operations is the placing of the intraocular lens to the sclera by fixing it with or without suture. In prior art, the scleral fixation operations were realized by fixing the lens to the sclera by stitching through the stitch holes present on the haptics of the lens. In this embodiment, a special lens, which is designed by taking this technique into consideration, has holes on its haptics and made of PMMA (polymethylmethacrylate=acrylic glass) , is used. These lenses which are made of PMMA are rigid and they can not be folded. Therefore, in order to place the lens into the eye, the surgical incision has to be large. Large incision give rise to astigmatism, higher number of sutures to stitch the incision, increased risk of infection, increased feeling of stinging in the eye due to increasing number of sutures, longer operation time and a more traumatic operation as a result of them. Furthermore, the sutures which are used to attach the lens to the sclera causes erosion in the tissue in longterm, breaking of the sutures due to abrasion, episcleritis and feeling of discomfort in the eye. In this situation, generally, a new operation is needed to replace the lens with a new one. On the other hand, it the new scleral fixation technique, in order to eliminate these disadvantages of the suture, the foldable lens is fixed to the sclera by being stuck from its haptics and no suture (stitch) is used. However, there are no lenses designed for this purpose. In this technique, foldable, acrylic, three piece lenses are used which are in fact manufactured for a different purpose and used for sulcus lens implantation.
The usage of three piece sulcus lens in the sutureless scleral fixation technique leads to some disadvantages since it is not produced for this purpose.
• First of all, the sulcus lenses are not compatible with the anatomical structure of the sclera,
• Their stability is weak at the point where . they are located,
• It may give rise to serious complications such as the dislocating and dropping of the lens into the vitreusa during the placement of the lens and after the placement.
• Their placement into the eye is troublesome and requires a technique traumatic for the eye,
• Furthermore, additional expensive materials such as microforceps and fibrine adhesive are needed during this application,
• The operation time is extended since the technique is complicated .
With the usage of the sutureless scleral fixation lens designed for the sutureless scleral fixation technique, it is aimed to overcome the disadvantages mentioned above. Object of the Invention :
The object of the invention is to create a lens structure which is precisely compatible with the form and the anatomic structure of the sclera by the virtue of its specially designed flat haptic structure and which is specific to sutureless scleral fixation applications. Another object of the invention is to improve the stability of the lens by providing a large contact surface with sclera by the virtue of the special haptic and the haptic feet design, and by increasing the adherence power to the tissue by the way of the geometrical shapes and the holes thereon and thus, to minimize the complication risks due to low stability experienced in the other lens practices.
Another object of the invention is to minimize the serious complication risk such as dropping of the lens into the eye by increasing the attachment strength to the sclera and the lens' stability by the virtue of the double haptic feet and haptic holders present in the special haptic structure.
Another object of the invention is to bring down the costs by eliminating the need for additional materials such as fibrin adhesive, since the lens is placed into the eye with the guidance of the sutures connected to the haptic holes and since the stabilization power is high thanks to the microforceps used for catching the haptic and to the haptic feet design.
Another object of the invention is to minimize the stinging feeling, astigmatism (diffraction failure) and the infection risks experienced by the patient in large incisions by the virtue of the folding feature of the lens which makes it possible to place the lens into the eye with a small incision.
Another object of the invention is to shorten the operation 5 time since the placing of the lens is technically safer, easier and atraumatic.

Description of the Invention : The sutureless scleral fixation lens subject to the invention is basically composed of lens body (1) and at least two haptics (2). Haptics (2) are composed of haptic legs (2.1) which bind each haptic (2) to the lens body (1) from at least one point; and haptic feet (2.2) provided at the tip which provides the attachment of the haptic to the eye. Each haptic feet (2.2) comprises haptic holders (2.2.1) and haptic holes (2.2.2) which strengthen the attachment of the lens to the tissue and increase the stability of the lens in the tissue. Haptic holders (2.2.1) are protrusions with different geometric forms which may be present on the surfaces or on the sides of the haptic feet (2.2). Haptic holes (2.2.2) are the holes with different geometric forms which may be present on the surface of the haptic feet (2.2) and through which the suture can pass easily.
The sutureless scleral fixation lens subject to the invention is in a foldable form. By the virtue of said form, the sutureless scleral fixation lens is located into the anterior chamber by being taken into the eye by being folded and then, the guide sutures are just bound (without stitching) by being passed from the haptic holes (2.2.2) . The guide sutures can be passed from the haptic holes (2.2.2) easily since their dimensions are appropriate for the structure of the guide sutures. With the guidance of these guide sutures, the lens haptics (2) are taken out through the scleral incision point. Following this step, the guide sutures are cut and completely taken out. The scleral channel is opened by a surgical blade in such a way that it will be equal to 50% of the thickness of sclera. Haptic feet (2.2) are stuck into this scleral channel. Thus, half of the thickness of the scleral tissue remains over the haptic feet (2.2) and the other half remains below. Said guide sutures just assist the operator for placing the lens into the sclera, they are not used for stitching the lens to the tissue, namely, the operation is done sutureless.
By the virtue of flat and large structure of the haptic feet (2.2) of the sutureless scleral fixation lens subject to the invention, a large contact surface is provided with sclera and thus, the attachment strength of the lens to the tissue is increased. The healing tissue (collagen tendons) attaches the lens to the sclera by passing through the haptic holes (2.2.2) having different geometric forms such as hole/channel in such a way that it forms a bridge between two sclera layer of half thickness and thus, it helps lens to stick to the eye. The haptic holders (2.2.1) having different geometric forms such as nick/notch etc. at the haptic feet (2.2) help the lens to be stabilized in the eye by increasing the mechanical attachment of haptic feet (2.2) between the sclera layers.
Since the sticking of the lens to the eye is provided by the scar tissue passing through the haptic holes (2.2.2) and the haptic holders (2.2.1), there is no need for an expensive additional material such as fibrin adhesive. Since the attachment of the lens to the eye is provided by the guide suture tied up through the haptic holes (2.2.2) there is no need for an expensive additional equipment such as microforceps.
The haptic feet (2.2) which have a flat form for being consistent with the spherical-flat structure of the sclera, are located vertical to the surface based on the flat surface. In their structure, the haptic feet (2.2) may comprise haptic holes (2.2.2) which are shown in Figure 4 or haptic holders (2.2.1) which are shown in Figure 5 or may comprise both of them. The angle between the haptic legs (2.1) and the optic body (1) to which the legs are connected maybe 0° to 15°. In an embodiment of our invention, the angle between the haptic leg (2.1) and the optic body (1) is given as 6° to 10°. The distance between two haptic feet (2.2) which are located face to face is between 12mm-24mm and in an embodiment of our invention, this distance is given as 14 mm.
In each haptic leg (2.1), there may be at least one haptic foot (2.2) as shown in Figure 3 or two or more. In the form of multiple haptic feet (2.2), the lens is fixed into the eye with four or more haptic feet (2.2) and thus with more haptic holders (2.2.1) and haptic holes (2.2.2).
