- the metal ring of the invention it is possible to use the metal ring of the invention to perform functions similar to those of the Flieringa ring and, in the event of an HOE, the surgeon can quickly couple the closure element ai metal ring by means of the coupling ring. This is achieved, thanks to the lens attached to the coupling ring, to block bleeding much more quickly compared to the solutions used today.
- the diameter of the closure element can be between 12 mm and 18 mm.
- the coupling between the coupling ring and the metal ring can be carried out in different ways.
- the coupling ring has magnetic properties for coupling the metal ring. That is to say, The coupling ring is shaped like a magnet so that it attracts the metal ring. This configuration is advantageous because it allows an almost immediate coupling of the closure element to the metal ring.
- both the coupling ring and the metal ring can have any cross-sectional shape as long as it allows the magnetic coupling described.
- the coupling ring has a cross section that has a cavity whose shape is complementary to the shape of the cross section of the metal ring. That is, the coupling ring has on one of its sides a channel that runs along its entire circumference and has a complementary cross section of the cross section of the metal ring.
- the metal ring would be inserted tightly into the interior of the cavity, thus being locked inside to prevent a possible decoupling.
- This configuration is advantageous because it increases the stiffness of the coupling between the closure element and the metal ring.
- the cross-sectional shape of the metal ring is complementary to the shape of the cross-sectional cavity of the collection ring.
- the cavity of the coupling ring may have a parallelepiped shape (it could be rectangular, square, etc.), in which case the metal ring would have a correspondingly parallelepiped cross section (correspondingly, it could also be rectangular, square, etc. .).

- Said fasteners can have different diameter and height so that they can adapt optimally to the different types of lenses available for surgery.
- the lens can in principle have any shape, type and material as long as it blocks bleeding when it is fixed to the metal ring through the coupling ring.
- the lens is a transparent lens made of plastic, for example polyethylene methacrylate.
- the lens is made of a material compatible with paracentesis, such as silicone.

- the lens design must allow the adaptation of surgical lenses that assist in the visualization of! posterior segment (curvature around 20 s in the optical zone), the lens is similar to a rigid corneal scleral lens with a central curvature in its optical zone, transition zone and anchor zone to the coupling ring.
- the device of the invention adequately solves the problems described above, since it allows an HOE to be tackled almost immediately. The following briefly describes how to use this device.
- the device according to the invention When the device according to the invention is used, it starts from a situation in which the metal ring is sutured with sclera.
- the use of metal rings of this type sutured to sclera in penetrating keratoplasty surgeries, such as the Fiieringa ring, is known.
- the ring helps maintain the architecture of the eyeball when the internal content is exposed to! Remove the injured cornea.
- it has been used to counteract the hypotonia caused by the surgical procedure and thus decrease the probability of HOE. If an HOE occurs in this situation, it can be stopped almost immediately by collecting the closing element on the metal ring. To do this, simply attach the coupling ring to the metal ring by means of the magnetic, mechanical or sealing joint in question.
- the lens serves as a barrier to prevent bleeding.
- the device of the invention allows a Immediate action for rapid recovery of airtightness of! eyeball, avoiding further damage that may be irreparable.
- Current treatments require a longer time, thereby increasing the risk of loss of intraocular content.
- the device of the invention allows to treat an HOE in a simpler, cleaner and controlled way, without sutures, use of viscoelastic, or of temporary keratoprostheses.
- the device of the invention replaces the temporary keratoprostheses, allowing the adaptation of surgical lenses that assist the visualization of the posterior segment.
- the device of the invention in its version that allows paracentesis (for example, silicone lens), allows surgery through the lens.
- paracentesis for example, silicone lens
- the device of the invention has utility in experimental surgery both in experimental animals and in eyes from donation. This device could be especially useful for the training of new surgeons who want to perform intraocular surgery on human balloons, since corneal edema is usually observed that makes it impossible to practice certain surgeries. In this case the opaque cornea would be replaced by the device of the invention.

- the coupling ring (32) has an essentially rectangular cross-sectional shape on whose lower side there is a cavity (321) that also has a rectangular shape that is complementary to the rectangular shape of the metal ring (2) described above. . That is, the cavity (321) forms a recessed channel of rectangular shape that runs the entire circumference of the lower side of the coupling ring (32).
- the curvature of the lens (3) causes the channel formed by the cavity (321) of the coupling ring (32) to be oriented with a certain inward inclination.
- the coupling ring (32) has magnetic properties.
- Figs. 3a and 3b show the process of coupling the closing element (3) to the metal ring (2). It is noted that the metal ring (2) fits perfectly in the channel formed on the lower surface of the collection ring (32). The magnetism of the coupling ring (32) attracts the metal ring (2), thus preventing them from uncoupling undesirably.
- Figs. 4a and 4b show a second example of a metal ring (2) according to the invention having a circular cross-section. It would therefore be a ring (2) very similar to the known Flieringa ring.
- Figs. 5a and 5b show a second example of a closure element (3) where the coupling ring (32) has a semicircular cross-sectional cavity (321). Therefore, in this case the lower surface of the coupling ring (32) has a semicircular channel that runs along its entire circumference. Also in this example, the semicircular channel formed by the cavity (321) of the coupling ring (32) is oriented with a certain inclination inward, a consequence of the curvature of the lens (31) to which it is fixed. As in the first example, the coupling ring (32) has magnetic properties.
- FIGs. 6a and 6b show the coupling of the closing element (3) on the metal ring (2) of this second example of device (1) according to the invention.
- FIG. 9 A third example of a device of the invention is shown in Figure 9, with a metal ring (2) and a closure element (3), in which the joint between these components is a seal joint.
- the sealing joint consists of the closing by means of a material of elastomeric nature of the ring (32) of coupling with the metal ring (2).
- the coupling ring (32) is made of an elastomeric material, preferably medical silicone or polyurethane.
- Figure 12 shows an example of a device of the invention with a metal ring (2) and a closure element (3), in which the joint between these components is a mechanical joint.
- the metal ring (2) has grooves (40) and the coupling ring (32) has protrusions (41), so that fixing and / or sealing of the metal ring (2) is allowed with the collection ring (32).
- Figure 13 shows an example of a device of the invention with a metal ring (2) and a closure element (3), in which the joint between these components is a joint magnetic as described above.
- Figures 16 and 17 show an example of a coupling ring (32) of a closing element (3) of a device of the invention to which a surgical entity (50) has been adapted.
- Figures 14 and 15 show only the coupling ring (32) of Figures 16 and 17, to which several types of surgical lens can be attached.
