Description
DESCRIPTION
INTRA OCULAR LENS
Technical Field
The present invention is in respect of intra-ocular lenses that are used in cataract surgery. After the cataract has been removed by surgical methods, the lens is being placed inside the capsule.
Prior Art
The purpose of the cataract surgery is to provide sight again by way of removing the opaque lens. Presently, with the up to date surgical techniques, the purpose is to provide the best sight in the shortest time possible after the surgery without the requirement of any supporting devices.
Presently, cataracts surgery is enjoying the renovations that are being introduced constantly. Factors such as the technologic developments, the increase in the number of surgical methods, the reduction in surgical incision, and their refractive and sight improved results have brought along decreased intra-operative and postoperative complications.
The technological developments that are used in cataract surgery presently had made it possible for the size of the surgical incision^to be reduced. The reduced sizes in the surgical incision, had also taken part during the first years of the development of cataract surgery during the shifting from intra-capsular surgery to extra-capsular surgery.
Yet a bigger stride had been made with the introduction of phacoemulsification and the use of intra-ocular lenses and thus the length of the incision had been reduced to less than 3,0 mms. The reduction in the incision lengths is related to a decrease in the post-operative intra-ocular inflammation, in the complications resulting from the wound site, in the astigmatism born out of the surgery, in the
duration of the surgery, in the tissue trauma and in the post-operative rehabilitation.
The other developments are in respect of intra-ocular lenses. With the standard lenses, the patient is in need of additional glasses for short sight focusing after the surgery. This problem is being solved to a degree with accommodative and multifocal lenses. The biggest problem that we come across with the accommodative lenses is the decrease in its effectiveness due to the decrease in the movement capability of the lens optic as a result of the fibrosis taking place in the frontal capsule of the lens in time. The major problems that we come across with the multifocal lenses are the decrease in the quality of sight due to the telescopic lens dioptres and the movements of light and the reflections. The other significant lenses that have been developed are the toric lenses for the purposes of the correction of astigmatism along with the cataract. However the major problem with them is that the lens could get into rotation and thereby the decrease in the correction of astigmatism.
Since years, cataract surgery is being applied as a standard procedure to millions of people worldwide. The swiftness of the post-operative rehabilitation time and the decrease in the requirement for wearing glasses for the patients and decreases the requirement to glasses and simultaneously increases the satisfaction of the patients.
In terms of the known state of the technique, within the European Patent Document with the number: EP 2422747; an intra-ocular implant is being explained. This invention is in respect of an intra-ocular implant that is applied with cataract surgery or with a surgical procedure such as refractive lens replacement. The haptics are not of an inflatable structure.
In terms of the known state of the technique, within the United States Patent Document with the number: US 20080027540; an intra-ocular lens is being explained. There is a narrow and a wide section in the haptic region of this lens. For the purposes of providing accommodation of the optics, there are hinge
sections for providing the forward and backward movements. The haptics are not of an inflatable structure.
In terms of the known state of the technique, within the International Patent Document with the number: WO 901 1736; an intra-ocular lens is being explained that could be widened using a haptic. After the lens is being inserted into the eye, the haptic region could be inflated using a special liquid. The optic is fixed and there are no hinges between the optic and the haptic.
Detailed Description of the Invention
An intra-ocular lens had been shown in the attached figure for the purposes of achieving the target of the present invention.

The parts that make up the intra-ocular lens that is subject of the invention had been numbered in the attached drawings as follows:
1- Intra-ocular lens
2- Eye
3- Capsule
4- Injector
5- Haptic
6- Optic
7- Hinge An intra-ocular lens (1) that is subject of the invention consists of the following parts:
- An eye (2),
- A capsule (3) that is located inside the eye (2) that serves as the housing for the intra-ocular lens (1),
- An injector (4) for the purposes of inflating the haptic (5) of the intraocular lens (1) exteriorly that has been implanted into the eye (2) through a small incision,
- An inflatable haptic (5) with air that is connected to the optic (6) and that is aiming to get fixed by filling the inside of the periphery of the capsule (3),
- An optic (6) that is connected to the haptic (5) and that is available to move in accordance with the situation inside the capsule (3),
- A hinge (7) that provides the link between the optic (6) and the haptic (5) and that provides for the forward and backward movement of the optic (6). An ideal intra-ocular lens (1) should be available for insertion into the eye (2) with ease, should be of the physical and chemical structure as not to trigger inflammation, should remain stable inside the eye and should be able to provide the best optical results. Presently, the intra-ocular lenses (1) are being manufactured using processes such as turning machine cuts, cast moulds or
injection moulds. The intra-ocular lens (1) basically consists of two sections as the optic (6) and the haptic (5).
The optic (6) section is the section in the centre having refractivity and that provides for the sight. It could be made up of various materials. These materials are required to be transparent, resistant to changes in heat, durable, should not create an inflammatory response, and should maintain its smooth surface and should not show deformations in time and should have perfect optical qualities.
The optical (6) diameter of the intra-ocular lenses (1) could be between 4,5 and 7 mms. The optical (6) width should be able to cover the pupilla width during darkness. However as the width increases, it becomes harder to insert the lenses (1). Haptic (5) section is the part that fixes the lens and makes it possible for the lens (1) to maintain its position inside the eye. The intra-ocular lens (1) could be placed both into the frontal chamber or the rear chamber as a front chamber angle supported lens, an iris fixation lens, an irido-capsular lens and as a rear chamber lens (1). Presently, the use of front chamber lenses has decreased considerably.
The rear chamber intra-ocular lens (1) is generally placed in two different fixations.
In sulcus positioning, the haptic (5) of the intra-ocular lens (1) relies either on the ciliary sulcus (the angle between the iris and the corpus ciliaris) or on the ciliary processes. It is relatively easier to insert into the eye. The haptic (5) and the optic (6) are behind the iris and generally the movements of pupilla remain in their physiologic position. In case the capsule (3) had been inserted in a larger manner, in cases with increased in-vitreus pressure and under circumstances where the zonula are weak; sulcus positioning is safer. The capsules (3) could be applied after the lacerations. In the secondary rear chamber intra-ocular lens (1) implantations; the sulcus positioning is preferred.
In intra-capsule (3) positioning, the intra-ocular lens (1) is placed inside the capsule (3) pouch between the rear capsule and front capsule periphery. Intra-
ocular lenses (1) has got the following advantages such as; they are in the anatomic position, the decentralisation risk is less, they are at the maximal distance to the cornea, they are isolated from the uveal tissue, the blood-aqueous barrier's integrity is maintained, the migration of the lens (1) material over to the rear capsule (3) is eliminated since the lens (1) is being tightly besieged by the capsule (3) pouch, the possibility of post-operative iris pigment dispersion is reduced and it is easy to remove if and when required.
The section that is passing from the optic (6) to the haptic (5) of the lens (1) is encircled in 360 degrees and it is movable. The haptic (5) section consists of an empty balloon and the same is being inflated with air inside the capsule (3). Since the haptic (5) is created inside the capsule (3) later, and since the optic (6) is pliable; an implantation with a small incision is made possible. Then the haptic (5) is inflated and thereby complete contact with the capsule (3) is provided and thereby there is no lens (1) rotation and it is due to this reason that an advantage is created in toric lenses. The restraint of the haptic (5) on the capsule (3) could obviate the focusing of the rear lens. The restraint of the haptic (5) on the capsule (3) is also preventing the fibrosis of the front capsule. The movable part at the connection point of the optic (6) and the haptic (5) and the lens (1) namely the hinge (7) is useful for accommodation and provides focusing in short sight. The explanation of the lens is possible by easily perforating the haptic (5) without having to widen the incision and without having to cut the lens (1).
The lens (1) that has been placed inside the cartridge is being implanted into the capsule (3). The haptics (5) of the lens (1) that has been placed into the capsule (3) is being formed as a result of giving air with the injector (4). The lens (1) maintains its normal position with the long sight, and as for the short sight requirements, it moves forwards. This movement is obtained with the hinge (7).
