Definitions
- This invention relates to lens implants for insertion in the human eye from which the natural lens has been removed with an extra-capsular extraction.
- Such lens implants consist of a lens made of polymethyl methyacrylate (PMMA) having holding portions projecting from its periphery to hold the lens in position in the eye between the posterior capsule and the iris after the implant has been inserted through an incision at the junction of the cornea and the sclera.
- the holding portions are usually in the form of closed loops or curved arms, which have one end free and are usually also known as loops, lying in the plane of the lens.
- the loops are flexible and resilient and in existing lens implants are of various shapes.
- the closed loops or curved arms are made of Prolene, which is a polypropylene and are fixed to the periphery of the lens. It has been found however that over a long period of time the Prolene is subject to some bio-degradation and if degradation takes place, there is a risk that the lens may become displaced in the eye unless sufficient fibrous growth has occured around it to hold it in place.
- the aim of the present invention is to provide a lens implant for insertion in the posterior chamber of a human eye after an extra-capsular extraction, the implant comprising a lens with holding portions of PMMA so that the problem of degradation is overcome, and in which the holding portions are so formed that insertion into the eye is facilitated while the maintenance of the positioning of the implant in the eye is improved.
- such a lens implant which comprises a lens of PMMA with two similar holding loops or arms projecting from the periphery of the lens, each loop or arm lying substantially in the plane of the lens and being open-ended with one end fixed to the lens and the other end free, is characterised in that the loops or arms are of PMMA and each has one end formed integrally with the lens, the loops or arms being substantially diametrically opposite each other around the periphery of the lens, and each loop or arm, starting from the end which is integral with the lens, has a first portion extending substantially radially outwards from the lens, then extending around a sharp bend into a second portion of a curvature such that it follows, but is spaced radially outwards from, the periphery of the lens, a third portion which extends from, and is of less curvature than, the second portion, and a fourth portion which extends from the third portion and is of a greater curvature, substantially similar to that of the second portion
- the implant as a whole can be inserted through the incision in the eye and through the dilated iris into the posterior chamber more easily than can be done with existing forms of lens implant intended for insertion into the posterior chamber.
- the shapes and flexibility of the loops or arms are such that the lens is held very securely in position regardless of whether the radially outer parts of the loops contact the anterior capsular flaps, which remain after removal of the anterior capsule, or the ciliary sulcus in between the posterior capsule and the iris.
- the two loops or arms preferably lie in a flat plane which is the plane containing the periphery of the lens, but they may alternatively lie in the planes which are inclined to this plane by a small angle of up to 10° and it is this that is meant by saying that the loops or arms lie substantially in the plane of the lens.
- each loop is of rectangular cross-section and of constant thickness perpendeicular to the plane of the lens.
- the first portion is then of greater width in this plane than the other portions to provide its greater stiffness.
- the width of the first portion tapers from the periphery of the lens to the beginning of the second portion and preferably the width of the second portion tapers from the first portion to the third portion.
- the third portion and the major part of the fourth portion are then preferably of constant width.
- the width of the fourth portion of each loop is preferably increased at its free end and both the wider free end part and the first portion are preferably provided with positioning holes extending through them perpendicular to the plane of the lens.
- These positioning holes assist in moving the lens into the exact required position after it has been inserted and, after insertion, material of the eye tends to grow and penetrate through the holes to anchor the lens implant more firmly in position.
- the implant is preferably made, as is usual, of PMMA of CQ quality and in one example the material is PMMA CQ 6, which is manufactured by Imperial Chemical Industries Limited.
- FIG. 1 is a front elevation of the implant
- FIG. 2 is a side elevation as seen from the left-hand side of FIG. 1.
- the implant comprises a lens 1 and two holding loops 2 all of which are formed integrally with each other of PMMA CQ 6 quality.
- Each of the loops 2 has a first portion 3 which projects substantially radially from the periphery of the lens 1 and is of substantial width so that it is relatively stiff against bending in the plane of the lens 1.
- the first portion 3 is connected around a sharp bend 4 to a second portion 5 which has a curvature such that it is substantially concentric with the periphery of the lens 1.
- the portion 7 has its tip 8 widened and a positioning hole 9 is formed in the widened tip 8.
- a second positioning hole 9 is formed in the portion 3.
- the portions 3 of the two loops 2 are positioned diametrically opposite each other around the periphery of the lens 1 and in consequence the loops 2, which are the same as each other, are symmetrically disposed around the lens.
- the portions 5, 6 and 7 are flexible and resilient so that when the loops 2 are bent in the plane of the lens with the portions 7 being pushed towards the periphery of the lens, the tip 8 of one loop will come into contact with the portion 5 of the other loop and the two loops taken together form a ring, which is of generally circular shape, extending around, but spaced from the periphery of the lens 1.
- the loops are squeezed inwards into these positions to enable the lens implant as a whole to be inserted into the posterior chamber of the eye in front of the posterior capsule.
- the lens 1, which is plano-convex as can be seen from FIG. 2, has a diameter of 5.5 mm.
- Both the loops 2 have a constant thickness of 0.14 mm perpendicular to the plane of the lens.
- the portion 5 of each loop has a width of 0.22 mm adjacent its junction with the portion 3 and the width tapers uniformly to 0.17 mm at the junction between the portions 5 and 6.
- the portions 6 and 7 have a constant width of 0.17 mm up to the widened tip 8.
- the positioning holes 9 have a diameter of 0.4 mm.
- the maximum overall dimension of the lens implant, that is the height as seen in FIG. 1, is 13.5 mm and the minimum overall dimension, that is the width as seen in FIG. 1, is 8.0 mm.
