Description

[0001] Phakic intraocular lens

[0002] The invention relates to a phakic intraocular lens.

[0003] In patients with nearsightedness (myopia), it is possible to improve vision by implanting a phakic intraocular lens (IOL) into the eye. The natural lens of the eye remains in place. This is particularly beneficial from a medical perspective for younger patients whose natural lens is neither cloudy nor hardened, as occurs in cataracts. A phakic IOL thus supports the natural lens.

[0004] Figure 1 shows a partial cross-section through a human eye 200 with a cornea 201, an anterior chamber 203, and a posterior chamber 204, with an iris 202 located between the two chambers 203 and 204. The iris 202 limits the amount of light entering the eye and reaching a lens 207 located behind the iris 202, which is contained within a capsular bag 205. The capsular bag 205 is held in place by zonular fibers 208, which originate from the ciliary body 209. The zonular fibers 208 can contract or relax, thereby stretching or compressing the elastic lens 207 and thus producing different refractive powers. The eye 200 has an optical axis 211, primarily determined by the natural lens 207.

[0005] If a phakic intraocular lens 1 is to be implanted into an eye 200, it can be placed in the anterior chamber 203 or in the posterior chamber 204. Placement in the anterior chamber, i.e., in front of the iris 202, can lead to corneal trauma 201 due to the unavoidable contact of the intraocular lens with the inner surface of the cornea 201. Such trauma can have serious consequences, as the cells on the inner surface of the traumatized cornea cannot regenerate and can develop towards the center of the cornea, i.e., in the direction of the eye's optical axis.

[0006] Such a disadvantage can be avoided if the phakic intraocular lens 1 is inserted into the posterior chamber 204. The disadvantage of this is that there is relatively little space available for an implant in the posterior chamber 204. A limitation along the optical axis 211 of the eye is created, firstly, by the iris 202, which is located on the upper surface of the

[0007] 2024P00033WO - 11.12.2025 The intraocular lens 1 should be able to move, particularly on a top surface 3 of an optical body 2 of the intraocular lens 1. Furthermore, the intraocular lens 1 is bounded by the capsular bag 205 and the natural lens 207 contained therein, which can move and change shape due to the activity of the zonular fibers 208, i.e., increase or decrease in thickness. The phakic intraocular lens 1 should be designed such that the capsular bag 205 does not touch a bottom surface 4 of the optical body 2 of the intraocular lens 1, so that movement of the natural lens 207 is not impeded. Perpendicular to the optical axis 211, the posterior chamber 204 is bounded by the ciliary sulcus 210, which is a depression between the iris 202 and the ciliary body 209.The phakic intraocular lens 1 must be large enough that its ends touch the ciliary sulcus 210 so that it is held securely in a plane perpendicular to the optical axis 211.

[0008] However, after implantation of a phakic intraocular lens 1, it may happen that a patient reports blurred vision, even though the optical values ​​of the intraocular lens to be implanted were determined with great care and are correct.

[0009] Therefore, one challenge is to create a phakic intraocular lens that provides greater reliability for good vision. The intraocular lens should be easy to implant and allow for deformation by the iris and the natural lens of the eye, as well as ensuring secure fixation in the posterior chamber.

[0010] The problem is solved by the subject matter of independent claim 1. Advantageous further developments are the subject matter of dependent claims.

[0011] The phakic intraocular lens comprises: an optical body with an optical axis perpendicular to a horizontal and vertical axis of the intraocular lens in plan view, wherein the horizontal axis and vertical axis lie in a tangential plane to a top surface of the optical body, wherein the optical body has a diameter in plan view, and a haptic connected to the optical body, which consists only of a first haptic body and a second haptic body, wherein the first haptic body has a first inclination zone and a first bearing zone, and the second haptic body has a second inclination zone and a second bearing zone.

[0012] 2024P00033WO - 11.12.2025 wherein, in an unloaded state of the phakic intraocular lens, the first inclination zone and the second inclination zone are arranged inclined to the tangent plane in an angular range with an amount between 15° and 40°, and the first support zone is arranged inclined to the first inclination zone in an angular range with an amount between 15° and 50°, and the second support zone is arranged inclined to the second inclination zone in an angular range of 15° to 50°, wherein the first haptic body and the second haptic body are plate-shaped in plan view and without a projecting spring arm, wherein the first haptic body is formed from a single part and the second haptic body is formed from a single part, and the first haptic body and the second haptic body are connected to each other so that a one-piece haptic is formed, wherein the first support zone has two opposing rounded first corner zones,wherein, along the vertical axis, a first vertical distance from the optical axis to a first envelope line, which runs parallel to the horizontal axis at a first outer edge of the first corner zones, is greater than a second vertical distance from the optical axis to a second outer edge of a first intermediate area between the first corner zones, wherein the second support zone has two opposing rounded second corner zones, wherein, along the vertical axis, a third vertical distance from the optical axis to a second envelope line, which runs parallel to the horizontal axis at a third outer edge of the second corner zones, is greater than a fourth vertical distance from the optical axis to a fourth outer edge of a second intermediate area between the second corner zones, wherein the sum of the second vertical distance and the fourth vertical distance is greater than the diameter of the optical body,where, along the vertical axis, a fifth vertical distance from the optical axis to a first center of mass of the first haptic body is smaller than a sixth vertical distance from the optical axis to a second center of mass of the second haptic body.

[0013] The invention is based on the idea that a human eye is not necessarily perfectly symmetrical. If the optical axis of the eye does not exactly coincide with the optical axis of the phakic intraocular lens, a patient may experience blurred vision even though the eye was previously measured very accurately and without error, and the required intraocular lens was fitted.

[0014] 2024P00033WO - 11.12.2025 was calculated perfectly correctly and the phakic intraocular lens was inserted perfectly correctly in the ciliary sulcus. This problem can be solved by using a phakic intraocular lens in which the vertical distance from the optical axis of the intraocular lens to a first center of mass of the first haptic body is smaller than the vertical distance from the optical axis to a second center of mass of the second haptic body. Such a phakic intraocular lens is not symmetrical with respect to the horizontal axis of the optical body. This asymmetry allows for an offset of the optical axis so that the optical axis of the intraocular lens can be aligned with the optical axis of the patient's eye. This allows a patient whose eye is not perfectly symmetrical to achieve good visual acuity.

[0015] According to one embodiment of the invention, the first vertical distance from the optical axis to the first envelope line at the first outer edge of the first corner zones is smaller than the third vertical distance from the optical axis to the second envelope line at the third outer edge of the second corner zones. Viewed from the horizontal axis of the optical body, the first haptic body is therefore shorter than the second haptic body.

[0016] Another possibility is that the thickness of the first corner zone is less than the thickness of the second corner zone. A corner zone with a lower thickness has a smaller axial moment of inertia than a corner zone with a greater thickness, resulting in greater bending or compression when a force perpendicular to the optical axis of the intraocular lens is applied by the ciliary sulcus. This also leads to a vertical displacement of the optical axis of the intraocular lens and causes an asymmetry of the intraocular lens when it is implanted in the posterior chamber of the eye. This, too, allows the optical axis of the phakic intraocular lens to be better aligned with the optical axis of the eye.

[0017] According to a further embodiment, only the first haptic body has a first recess, which is arranged on a top or bottom surface of the first haptic body, or which is arranged between the top and bottom surfaces of the first haptic body, or which extends from the top to the bottom surface of the first haptic body. The recess on the top or bottom surface, or between the top and bottom surfaces, reduces the cross-section at that point, or, if it extends from the top to the bottom surface, forms a hole.

[0018] 2024P00033WO - 11.12.2025 in the haptic body. This results in the axial moment of inertia of the first haptic body being smaller than that of the second haptic body. Consequently, when a force is applied perpendicular to the optical axis from the ciliary sulcus, this also causes a greater bending or compression, thus shifting the optical axis of the intraocular lens. In this embodiment, the first vertical distance and the third vertical distance can be identical.

[0019] It is advantageous if the first recess is located in the first contact zone of the first haptic body. This allows the first contact zone of the first haptic body to be softer under a vertical force perpendicular to the optical axis than the second contact zone, which lacks a recess. Consequently, under the same force exerted by the ciliary sulcus on the contact zones, the first haptic body can deform somewhat more than the second, thus shifting the optical axis of the phakic intraocular lens. This embodiment also allows for intraocular lens asymmetry, where the first and third vertical distances can be identical.

[0020] Furthermore, it is possible that the first recess is located in a peripheral region adjacent to the optical body. This recess can be arc-shaped. This can lead to a relatively strong decoupling of the first haptic body from the optical body, allowing the first haptic body to move even more freely. This also enables a shift in the optical axis when a force perpendicular to the optical axis is exerted on the intraocular lens from the ciliary sulcus. This makes it possible to align the optical axis of the phakic intraocular lens with the optical axis of the eye, thus enabling good vision for the patient.

[0021] In a further embodiment, the first haptic body has a first recess which is arranged on a top or bottom surface of the first haptic body, or which is arranged between the top and bottom surfaces of the first haptic body, or which extends from the top surface to the bottom surface of the first haptic body, wherein the first recess is arranged in a first peripheral region adjacent to the optical body, wherein a second recess is arranged in a second peripheral region adjacent to the optical body in the second haptic body, wherein the second recess has a smaller area in plan view than the first recess. With the second recess

[0022] 2024P00033WO - 11.12.2025, the second haptic body can also be well decoupled from the optical body. However, since the second recess has a smaller area than the first recess, an asymmetry is achieved, so that an offset of the optical axis is possible if a force perpendicular to the optical axis is exerted on the intraocular lens from the ciliary sulcus.

[0023] It is also possible that Fresnel zones are formed on the underside of the optical body. These zones are advantageous because they reduce the volume of the optical body and, with a step height of up to 500 micrometers, create notches that reduce the lens's spring stiffness along the optical axis. If the Fresnel zones are located on the underside of the optical body, they only affect the optical image when the pupil is fully dilated, i.e., in complete darkness, which is negligible during daytime use.

[0024] According to a further embodiment, the first support zone lies in a first support plane and the second support zone lies in a second support plane, wherein the first and second support planes are arranged along the optical axis of the intraocular lens at a distance from each other in the range of 0.2 mm to 1.3 mm. Such an embodiment can be advantageous if, during a measurement of a patient's eye, it is found that the ciliary sulcus spans a plane that is not perpendicular to the optical axis of the eye, but rather inclined to it. The offset of the support zones along the optical axis of the phakic intraocular lens then allows the intraocular lens to be positioned such that its optical axis coincides with the optical axis of the eye.

[0037] Figure 2 shows a schematic top view of a first embodiment of a phakic intraocular lens 1 according to the invention. The intraocular lens 1 comprises an optic consisting of an optical body 2 with an optical axis 100 and a diameter D. The optical body 2 has an outer ring 37. The optical axis 100 is perpendicular to the plane of the drawing and orthogonal to a horizontal axis 110 and a vertical axis 120 of the intraocular lens. The horizontal axis 110 and the vertical axis 120 define a plane that is tangent to a top surface 3 of the optical body 2. The top surface 3 of the optical body 2 can be a perfectly flat surface, a convex surface, or a concave surface. The optical body 2 is surrounded by a haptic structure 10, which consists only of a first haptic body 11 and a second haptic body 16.

[0038] The first haptic body 11 and the second haptic body 16 are each formed from a single part and are connected to each other in the region of the horizontal axis 110 of the optical body 2, so that a one-piece haptic is formed. The first haptic body 11 and the second haptic body 16 surround the optical body 2 in the form of a truncated cone shell and along its entire circumference, the inclination of the cone shell descending from the optical body 2.

[0039] 2024P00033WO - 11.12.2025. The first haptic body 11 has a first inclination zone 30 and the second haptic body 16 has a second inclination zone 32. The magnitude of the inclination of the plane of the first inclination zone 30 to the tangent plane 130 and the magnitude of the plane of the second inclination zone 32 to the tangent plane 130, see Figure 10, is in an angular range between 15° < a < 40°. The first inclination zone 30 is longer along the vertical axis 120 of the intraocular lens 1 than along the horizontal axis 110 of the intraocular lens 1. Similarly, the second inclination zone 32 along the vertical axis 120 of the intraocular lens 1 is longer than along the horizontal axis 110 of the intraocular lens 1. This forms a haptic 10 that is essentially rectangular or plate-shaped in plan view. The haptic 10 has no spring arm or similar feature.This is advantageous because an intraocular lens with a plate-shaped haptic can fold easily and reliably and unfold safely again after implantation in the eye.

[0040] The vertical axis 120 forms a longitudinal axis of the intraocular lens 1, and the horizontal axis 110 forms a transverse axis of the intraocular lens 1. The first haptic body 11 has a first support zone 31 at an end opposite the optical body 2 along its longitudinal axis, and the second haptic body 16 has a second support zone 33 at an end opposite the optical body 2 along its longitudinal axis. The first support zone 31 is inclined to the first inclination zone 30 of the first haptic body 11 at an angle between 15° < β < 50°, and the second support zone 33 of the second haptic body 16 is inclined to the second inclination zone 32 at an angle between 15° < β < 50°. The first support zone 31 and the second support zone 32 form supports or feet for the phakic intraocular lens 1.

[0041] The first support zone 31 has two opposing first corner zones 41. Parallel to the horizontal axis 110, a first envelope line 42 can be drawn along a first outer edge 43 of the first corner zones 41. A first intermediate area 44, which represents a recess, is provided between the first corner zones 41. The outer edge of the intraocular lens 1 remaining between these corner zones 41 is designated as the second outer edge 45.

[0042] Similarly, the second support zone 33 has two opposing second

[0043] Corner zones 51. Parallel to the horizontal axis 110, a second envelope line 52 can be drawn at a

[0044] 2024P00033WO - 11.12.2025 Apply the third outer edge 53 of the second corner zones 51. A second intermediate area 54, which represents a recess, is provided between the second corner zones 51. The outer edge of the intraocular lens 1 remaining between these corner zones 51 is designated as the fourth outer edge 55.

[0045] Along the vertical axis 120, a first vertical distance a1 from the optical axis 100 to the first envelope line 42 is greater than a second vertical distance a2 from the optical axis 100 to the second outer edge 45. The first corner zones 41 thus project further forward than the second outer edge 45 of the intraocular lens 1 in the first intermediate region 44. This applies analogously to the opposite second haptic body 16: Along the vertical axis 120, a third vertical distance a3 from the optical axis 100 to the second envelope line 52 is greater than a fourth vertical distance a4 from the optical axis 100 to the fourth outer edge 55. The second corner zones 51 thus project further forward from the optical axis 100 than the fourth outer edge 55 of the intraocular lens 1 in the second intermediate region 54.When the intraocular lens 1 is inserted into a posterior chamber 204 of an eye 200, the first bearing zone 31 with the two opposing first corner zones 41 and the second bearing zone 33 with the two opposing second corner zones 51 come into contact with the ciliary sulcus 210. The sum of the second vertical distance a2 and the fourth vertical distance a4 is greater than the diameter D of the optical body 2, so that the intraocular lens 1 has a plate-like and essentially rectangular contour in top view.

[0046] In the embodiment shown in Figure 2, the first vertical distance a1 is smaller than the third vertical distance a3. As a result, a fifth vertical distance a5 along the vertical axis 120 from the optical axis 100 to a first center of mass S1 of the first haptic body 11 is smaller than a sixth vertical distance a6 along the vertical axis 120 to a second center of mass S2 of the second haptic body 16. The intraocular lens 1 is asymmetrical with respect to the horizontal axis 110.

[0047] Figure 3 shows a further embodiment of the intraocular lens 1 according to the invention. This embodiment differs from the embodiment shown in Figure 2 in that the first vertical distance a1 is equal to the third vertical distance a3. An asymmetry of the phakic intraocular lens 1 is achieved by the fact that only in the first

[0048] 2024P00033WO - 11.12.2025 Haptic body 11 has a first recess 14. The first recess 14 is provided in the first support zone 31 in the respective corner zones 41 and extends from the top 12 to the bottom 18 of the intraocular lens 1, see also Figure 5. This causes the fifth vertical distance a5 from the optical axis 100 to a third center of mass S3 along the vertical axis 120 to be smaller than the sixth vertical distance a6 from the optical axis 100 to a fourth center of mass S4 of the second haptic body 16.

[0049] Figure 4 shows a third embodiment of the intraocular lens 1 according to the invention. The first haptic body 11 has a first recess 14 in a first peripheral region 15, which adjoins the optical body 2. The first recess 14 extends in a circular arc along an angular range of approximately 160° around the optical axis 100 and reaches from the top 12 to the bottom 13 of the first haptic body 11. The second haptic body 16 has a second recess 19 in a second peripheral region 20, which adjoins the optical body 2. The second recess 19 also extends in a circular arc along an angular range of approximately 140° around the optical axis 100 and reaches from the top 17 to the bottom 18 of the second haptic body 16, but the second recess 19 is interrupted by webs 21. Thus, viewed from above, the first recess 14 is larger than the second recess 19.This creates an asymmetry such that along the vertical axis 120, the fifth vertical distance a5 from the optical axis 100 to the fifth center of mass S5 is smaller than along the vertical axis 120, the sixth vertical distance a6 from the optical axis 100 to the sixth center of mass S6. In this embodiment, the first vertical distance a1 is equal to the third vertical distance a3.

[0050] Figure 6 shows a cross-sectional view of a fourth embodiment of the invention. The first haptic body 11 has a first recess 14 on its upper surface 12, which, however, does not extend to the lower surface 13. Figure 7 shows a fifth embodiment in which a first recess 14 is arranged on the lower surface 13 of the first haptic body 11. Figure 8 shows a sixth embodiment of the invention, in which a first recess 14 is arranged between the upper surface 12 and the lower surface 13 of the first haptic body 11. These three embodiments have in common that the second haptic body 16 has no recess, thereby achieving an asymmetry of the intraocular lens 1.

[0051] 2024P00033WO - 11.12.2025 Figure 9 shows a cross-sectional view of a seventh embodiment of the invention, wherein a first thickness d1 of a first corner zone 41 is lower than a second thickness d2 of a second corner zone 51. This also achieves an asymmetry of the intraocular lens 1.

[0052] Figure 10 shows a cross-sectional view of an eighth embodiment of the invention. Fresnel zones 5 are formed on the underside 4 of the optical body 2, which have relatively high steps compared to diffractive structures. They can be designed to be helpful for the construction of the optical image. In addition, they reduce the thickness of the intraocular lens at this point. This allows for easier bending when a force is applied from the side or along the vertical axis 120, and thus reduces the spring stiffness of the intraocular lens along the vertical axis 120.

[0053] Figure 11 shows a cross-sectional view of a ninth embodiment of the invention. The first contact zone 31 of the first haptic body 11 lies in a first contact plane 34, and the second contact zone 33 of the second haptic body 16 lies in a second contact plane 35. The first contact plane 34 and the second contact plane 35 are offset from each other by a distance 36 along the optical axis 100. The distance 36 is greater than zero and lies in a range between 0.2 mm and 1.3 mm. If a plane spanned by the ciliary sulcus 210 is not perpendicular to the optical axis 211 of the eye 200, an intraocular lens 1 according to this embodiment can help to better align the optical axis 210 of the eye 200 with the optical axis 100 of the intraocular lens 1.
