Description

Technical Field

[0001] The present invention relates to a member for eye insertion and a method for inserting the member for eye insertion.

Background Art

[0002] Since the cornea has a gel-type material, expansion due to intraocular pressure occurs in the thin part of the cornea. In this case, the expanded part creates a curvature deviation, inducing visual abnormalities and also causing a tear film defect, resulting in dry eye. If the corneal expansion due to intraocular pressure continues, there is a possibility that the cornea may perforate at the end.

[0003] Corneal cross-linking, which is used to prevent existing corneal deformation, is a medical technique in which vitamin B2 is applied to the corneal stroma and then irradiated with ultraviolet light to strengthen the cross-linking between collagen fibers, increase the strength of the cornea, suppress the progression of keratoconus, and stabilize it.

[0004] Such corneal cross-linking has the drawback that the cross-linking is not made quantitatively uniform, the visual field becomes blurred after the operation, and the binding force decreases over time, which may lead to loss of effect.

[0041] Unless otherwise defined, all terms used in this specification, including technical or scientific terms, have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention pertains.

[0042] Terms defined as in a commonly used dictionary should be interpreted as having a meaning consistent with the meaning in the context of the related art and should not be interpreted as having an ideal or overly formal meaning unless clearly defined in this application. Furthermore, each configuration, process, step, or method, etc. included in each embodiment of the present invention can be shared within a range where there is no technical contradiction among them.

[0043] Hereinafter, with reference to FIGS. 1a and 13, an intraocular insertion member according to some embodiments of the present invention and an intraocular insertion method of the intraocular insertion member will be described. Figures 1a to 1d are schematic diagrams related to the constituent tissues of the cornea and drawings for explaining the process of corneal expansion due to intraocular pressure. Figure 1a shows a schematic diagram related to the constituent tissues of the cornea. Referring to Figure 1a, the cornea (L) of the eyeball can be divided into five layers. At this time, L1 can represent the corneal endothelium, L2 can represent the posterior limiting lamina (Descemet's membrane), L3 can represent the corneal stroma, L4 can represent Bowman's membrane, and L5 can represent the corneal epithelium. However, it is not limited to this, and the cornea of the eyeball can also be divided into more subdivided layers, and some layers can be omitted and named while being merged with other layers.

[0044] Generally, the thickness of the corneal epithelium (L5) is about 50 microns, and the thickness of the corneal stroma (L3) is 300 microns or more and 800 microns or less. At this time, when the thickness of the entire cornea (L) is 360 - 400 microns or less, the probability of corneal ectasia appearing is considered high. However, when the intraocular pressure is high, corneal ectasia may also occur even if the cornea is thick.

[0045] Figures 1b to 1d are drawings for explaining the process of corneal expansion due to intraocular pressure. The thin part of the cornea of the eyeball can expand due to intraocular pressure. For example, Figure 1b shows a part (101) where the cornea (L) has expanded in the direction of the arrow (Pa) due to intraocular pressure, and Figure 1c shows parts (102, 103) where the cornea (L) has expanded in the directions of the arrows (Pb, Pc) due to intraocular pressure.

[0046] At this time, the expanded part creates a curvature deviation and induces visual abnormality, and can also cause a tear film defect and lead to dry eye. If the corneal expansion due to intraocular pressure continues, in the end, the cornea may be perforated.

[0047] Figure 1d illustrates the biomechanical cycle related to the loss of the compensatory action of corneal expansion. The cycle illustrated in Figure 1d means that when it starts due to the asymmetry of the biomechanical property distribution, then the cornea becomes thinner, the stress increases, and finally the cornea deforms or redistributes its curvature compensatorily. Therefore, it is necessary to insert a biocompatible substance into the cornea to prevent the deformation or swelling of the cornea caused by intraocular pressure. Hereinafter, the member for eye insertion that performs such a function will be described in detail.

[0048] FIG. 2 illustrates a member for eye insertion according to some embodiments inserted into an eyeball. Referring to FIG. 2, FIG. 2 shows an upper region (201), a lower region (202), and a space (210) between the upper and lower regions of the member for eye insertion inserted into the cornea (L) of the eyeball. At this time, the upper region (201) and the lower region (202) of the member for eye insertion may each be in a semi-circular form.

[0049] Generally, when inserting such a member for eye insertion into the eyeball, after making a tunnel in the corneal stroma (FIG. 1a, L3), the upper region (201) and the lower region (202) of the member for eye insertion are inserted axially symmetrically. At this time, the progression of keratoconus can be suppressed by utilizing the principle of generating an arc-shortening effect of the cornea to flatten the central cornea.

[0050] However, such a member for eye insertion may have side effects in which the cornea at the site where the ring piece is inserted bulges, thereby inducing the generation of irregular refractive power and tear film deficiency. In addition, since the upper region (201) and the lower region (202) of the member for eye insertion are inserted axially symmetrically separated, the curvature of the portions (201, 202) where each region is arranged and the portions (210) where they are not arranged may change. Therefore, in this case, it may be difficult to uniformly improve the shape of the cornea with a spherical or elliptical curvature. Therefore, hereinafter, a new form of the member for eye insertion that can solve such problems will be described.

[0051] FIGS. 3A to 3C are drawings for explaining a member for eye insertion and a ring assembly according to some embodiments. FIG. 3a illustrates an eyeball insertion member (300) according to some embodiments, and FIG. 3b illustrates a ring assembly (310) of the eyeball insertion member (300) of FIG. 3a.

[0052] Referring to FIGS. 3a and 3b, the eyeball insertion member (300) can include a ring assembly (310) and a plurality of connecting members (e.g., 321 to 324). The ring assembly (310) can include a plurality of rings (311 to 314). At this time, the plurality of rings can have a common center (C). At this time, the plurality of rings (311 to 314) can have a concentric shape with different sizes from each other. However, it is not limited thereto, and the centers of the respective rings can be partially different.

[0053] In FIGS. 3a and 3b, the intervals between the respective rings (311 to 314) are shown to be the same, but it is not limited thereto, and the intervals between the respective rings can be partially different.

[0054] The plurality of connecting members (e.g., 321 to 324) can connect between the plurality of rings (311 to 314). According to some embodiments, each of the plurality of connecting members can be arranged at the same angle (α1) away from an adjacent connecting member with respect to the center (C), but it is not limited thereto.

[0055] Each connecting member, for example, reference numeral (321) in the drawing, can also be integrally formed to have a length from the smallest ring (314) to the largest ring (311), or can be formed as a set of detailed connecting members having a length approximately equal to the distance between each ring (between 311 and 312, between 312 and 313, between 313 and 314).

[0056] In FIG. 3a, the number of connecting members is shown as 16, but this is only an exemplary value, and the number of connecting members can be freely deformed. FIG. 3a shows a straight line in which each connecting member is connected from the minimum ring (314) to the maximum ring (311), but it is not limited thereto.

[0057] In some embodiments, the connecting member can also be connected between each ring (between 311 and 312, between 312 and 313, between 313 and 314) by a curve.

[0058] In some other embodiments, the connecting members can be formed to be different from each other separately between each ring (between 311 and 312, between 312 and 313, between 313 and 314). For example, the connecting member can also be formed to include one straight line between ring (311) and ring (312), two straight lines between ring (312) and ring (313), and one straight line between ring (313) and ring (314).

[0059] In some other embodiments, the connecting members can also be formed in a staggered connection manner between each ring (between 311 and 312, between 312 and 313, between 313 and 314). However, not limited to the above-described examples, the connecting member can connect between each ring in various ways.

[0060] The material of the plurality of rings and / or the plurality of connecting members can be a biocompatible substance. At this time, the biocompatible substance can be a product made or coated with a substance harmless to the human body. In some examples, the biocompatible substance can include, for example, polymethyl methacrylate (PMMA), gold, alloy, platinum, titanium, and stainless, etc., but is not limited thereto.

[0061] The thickness of the intraocular insertion member (300) can be, for example, 100 microns or less, but is not limited thereto.

[0062] FIG. 3c is a schematic diagram for explaining that a plurality of rings (311 to 314) of the ring assembly (310) and connecting members (for example, 321 to 324) are combined to show a kind of network form. By showing that a plurality of rings of the member for inserting into the eyeball and a plurality of connecting members intersect finely with each other, that is, a kind of network form, the member for inserting into the eyeball can wrap the form of the cornea and perform the role of a skeleton for holding it. Therefore, it may be useful for preventing deformation of the cornea due to intraocular pressure and improving and maintaining the curvature of the cornea to a spherical or elliptical surface.

[0063] FIG. 4 illustrates a member for inserting into the eyeball according to some embodiments. Referring to FIG. 4, the member for inserting into the eyeball (400) can include a ring assembly including a plurality of rings (411 to 414) and a plurality of connecting members (for example, 421 to 424). The plurality of rings (411 to 414) can have a common center (C). However, it is not limited thereto, and the centers of the respective rings may be partially different.

[0064] Each of the plurality of rings (411 to 414) can have an elliptical shape, different from the plurality of concentric rings (311 to 314) shown in FIGS. 3a and 3b. At this time, the plurality of rings (411 to 414) can be ellipses having the same eccentricity and different sizes from each other.

[0065] For example, in FIG. 4, it is illustrated that the long radius of the ring (414) with the smallest size is a1 and the short radius is b1, and the long radius of the second smallest ring (413) is a2 and the short radius is b2. At this time, the long radii (a1, a2) of the respective rings (413 and 414) are different from each other, and the short radii (b1, b2) are also different from each other, but the eccentricities of the respective rings (413, 414) calculated based on the ratio of the long radius to the short radius can be the same as each other. However, it is not limited thereto, and the eccentricities of the respective rings may be partially different from each other.

[0066] FIG. 4 shows that the intervals between the respective rings (411 to 414) are the same, but it is not limited thereto, and the intervals between the respective rings may be partially different. A plurality of connecting members (for example, 421 to 424) can connect between the plurality of rings (411 to 414). Each of the plurality of connecting members can be arranged at the same angle (α2) away from the adjacent connecting member with respect to the center (C), but it is not limited thereto.

[0067] At this time, each connecting member can also be integrally formed so as to have a length from the minimum ring (414) to the maximum ring (411), or can be formed as a set of detailed connecting members having a length approximately equal to the distance between each ring (between 411 and 412, between 412 and 413, between 413 and 414).

[0068] FIG. 4a shows that the number of connecting members is 16, but this is only an exemplary value, and the number of connecting members can be freely deformed. FIG. 4a shows that each connecting member is a straight line connecting from the minimum ring (414) to the maximum ring (411), but it is not limited thereto.

[0069] In one example, the connecting members can also connect between each ring (between 411 and 412, between 412 and 413, between 413 and 414) in a curve.

[0070] In other examples, the connecting members can be formed to be different from each other between each ring (between 411 and 412, between 412 and 413, between 413 and 414). For example, the connecting members can be formed to include one straight line between the ring (411) and the ring (412), two straight lines between the ring (412) and the ring (413), and one straight line between the ring (413) and the ring (414).

[0071] In another example, the connecting member can also be formed in a staggered connection manner between each ring (between 411 and 412, between 412 and 413, between 413 and 414). However, it is not limited to the above-described examples, and the connecting member can connect between each ring in various ways.

[0072] The material of the plurality of rings and / or the plurality of connecting members can be a biocompatible substance. At this time, the biocompatible substance can be a product made of or coated with a substance harmless to the human body. In some examples, the biocompatible substance can include, for example, polymethyl methacrylate (PMMA), gold, alloy, platinum, titanium, and stainless, etc., but is not limited thereto. The thickness of the intraocular insertion member (400) can be, for example, 100 microns or less, but is not limited thereto.

[0073] FIG. 5 illustrates an intraocular insertion member including an auxiliary connecting member according to some embodiments. Referring to FIG. 5, the intraocular insertion member (500) can include a ring assembly including a plurality of rings (511 to 514), a plurality of connecting members (521 to 523), and auxiliary connecting members (531 to 533).

[0074] The plurality of rings (511 to 514) in FIG. 5 are illustrated in a concentric form as in FIG. 3a, but are not limited thereto. As described above with reference to FIG. 4, each ring (511 to 514) in FIG. 5 can be in the shape of an ellipse with the same eccentricity and different sizes from each other.

[0075] FIG. 5 shows that each of a plurality of connecting members (e.g., 521 to 523) is arranged at the same angle (α3) away from an adjacent connecting member with respect to the center (C). Although FIG. 5 shows that the number of connecting members is 16, it is of course not limited thereto. The illustrated angle (α3) may be the same as or different from the angle (α1) in FIG. 3a and / or the angle (α2) in FIG. 4.

[0076] The auxiliary connecting members (531 to 533) may be arranged at locations where the respective connecting members (e.g., 521 to 523) are not arranged. In FIG. 5, for convenience of explanation, the auxiliary connecting members (531 to 533) are illustrated by dotted lines. Although FIG. 5 shows that the number of the auxiliary connecting members (531 to 533) is 3, this is merely an exemplary value and can be freely deformed.

[0077] The case where the thickness of the user's cornea is uneven can be covered through the arrangement of the auxiliary connecting member (531). For example, when the thickness of the eyeball cornea is thin at the first part and thick at the second part, the eyeball insertion member (500) can be inserted such that the first part corresponds to the position where the auxiliary connecting members (531 to 533) are arranged and the second part corresponds to the position where the auxiliary connecting members (531 to 533) are not arranged.

[0078] FIGS. 6a to 6e illustrate a set of eyeball insertion members according to some embodiments. FIGS. 6a to 6e show a first set (601, 602, 603, 610, 620, 630, 640) of eyeball insertion members in which the shapes of a plurality of rings are circular.

[0079] FIG. 6a shows a front view of eyeball insertion members (601, 602, 603) having different curvatures from each other. Each member for inserting into an eyeball (601 to 603) is illustrated as including four rings. That is, the member for inserting into an eyeball (601) is illustrated as including four rings (601a, 601b, 601c, 601d), the member for inserting into an eyeball (602) is illustrated as including four rings (602a, 602b, 602c, 602d), and the member for inserting into an eyeball (603) is illustrated as including four rings (603a, 603b, 603c, 603d). The connecting members between the respective rings are illustrated by dotted lines for convenience.

[0080] Referring to FIG. 6a, the curvature of the member for inserting into an eyeball (602) is larger than that of the member for inserting into an eyeball (601) and smaller than that of the member for inserting into an eyeball (603). That is, the first set of members for inserting into an eyeball can include a plurality of members for inserting into an eyeball (601 to 603) having different curvatures from each other. According to some embodiments, the first set of members for inserting into an eyeball can include a plurality of members for inserting into an eyeball having a curvature difference in units of 0.25 D.

[0081] Referring to FIGS. 6b and 6c, FIG. 6b shows the distance (r1) from the center (C) in the member for inserting into an eyeball (610) to the ring having the minimum size and the distance (r2) from the center (C) to the ring having the maximum size, and FIG. 6c shows the distance (r3) from the center (C) in the member for inserting into an eyeball (620) to the ring having the minimum size and the distance (r4) from the center (C) to the ring having the maximum size. At this time, r3 may be larger than r1 and r4 may be larger than r2. That is, the first set of members for inserting into an eyeball can include a plurality of members for inserting into an eyeball (610 to 620) in which the distance from the center to the ring having the minimum size among the plurality of rings and the distance from the center to the ring having the maximum size among the plurality of rings are different from each other.

[0082] Referring to Fig. 6d, the spacing between each ring of the ocular insertion member 630 is illustrated as d1, d2, and d3. As illustrated in Fig. 6d, d2 can be smaller than d1 or d3. That is, the first set of ocular insertion members may include an ocular insertion member (630) having multiple rings with non-constant spacing between them.

[0083] However, it will be appreciated that the first set of eye insertion members may not only include an eye insertion member (630) in which the spacing (d1, d2, d3) between each ring of a single eye insertion member (630) is not constant, as shown in FIG. 6d, but may also include multiple eye insertion members in which the spacing between each ring is constant but the spacing is different from one another.

[0084] Referring to Figure 6e, Figure 6e illustrates an eye insertion member (640) including a plurality of connecting members arranged spaced apart from each other at the same angle based on the center (C) and auxiliary connecting members (641 to 645) arranged in locations where the plurality of connecting members are not arranged. That is, the first set of eye insertion members may include an eye insertion member (640) including an auxiliary connecting member that is positioned in a location where the multiple connecting members are not positioned.

[0085] Taking Figures 6a to 6e together, the first set of eye insertion members (601, 602, 603, 610, 620, 630, 640) can include a plurality of eye insertion members that differ from each other in at least one of the following: the curvature of each eye insertion member, the distance from the center to the ring with the smallest size among the plurality of rings, the distance from the center to the ring with the largest size among the plurality of rings, the spacing between the plurality of rings, whether the spacing between the plurality of rings is constant, and the presence or absence of an auxiliary connecting member placed in a location where no connecting member is placed. However, without being limited to the above examples, the first set of eye insertion members may include eye insertion members having a wider variety of patterns and shapes.

[0086] Figures 7a through 7f illustrate a set of eye insertion members according to some other embodiments. Figures 7a through 7f illustrate a second set (701, 702, 703, 704, 705, 706, 710, 720, 730, 740) of eye insertion members in which the shape of the plurality of rings is an ellipse.

[0087] Figure 7a illustrates a front view of eye insertion members (701, 702, 703) having different curvatures from each other. Each eye insertion member (701 through 703) is illustrated as including four rings. That is, the eye insertion member (701) is illustrated as including four rings (701a, 701b, 701c, 701d), the eye insertion member (702) is illustrated as including four rings (702a, 702b, 702c, 702d), and the eye insertion member (703) is illustrated as including four rings (703a, 703b, 703c, 703d). The connecting members between the respective rings are illustrated by dotted lines for convenience.

[0088] Referring to Figure 7a, the curvature of the eye insertion member (702) is greater than that of the eye insertion member (701) and less than that of the eye insertion member (703). That is, the second set of eye insertion members can include a plurality of eye insertion members (701 through 703) having different curvatures from each other. According to some embodiments, the second set of eye insertion members can include a plurality of eye insertion members having a curvature difference in 0.25D units.

[0089] Figure 7b illustrates a schematic diagram of eye insertion members (704, 705, 706) having different eccentricities from each other. Referring to Figure 7b, the eccentricity of the rings included in each of the eye insertion members (704, 705, 706) is constant, but the eccentricity of the rings of the eye insertion member (705) is greater than the eccentricity of the rings of the eye insertion member (704) and less than the eccentricity of the rings of the eye insertion member (706). That is, the second set of eye insertion members can include a plurality of eye insertion members (704 to 706) with different eccentricities for each ring.

[0090] Referring to FIGS. 7c and 7d, in FIG. 7c, the distance (r5) from the center (C) to the ring having the minimum size and the distance (r6) from the center (C) to the ring having the maximum size in the eye insertion member (710) are shown. In FIG. 7c, the distance (r7) from the center (C) to the ring having the minimum size and the distance (r8) from the center (C) to the ring having the maximum size in the eye insertion member (720) are shown.

[0091] At this time, r7 may be larger than r5, and r8 may be larger than r6. That is, the second set of eye insertion members can include a plurality of eye insertion members (710 to 720) in which the distance from the center to the ring having the minimum size among the plurality of rings and the distance from the center to the ring having the maximum size are different from each other.

[0092] Referring to FIG. 7e, in FIG. 7e, the intervals between the rings of the eye insertion member (730) are shown as d4, d5, and d6. As shown in FIG. 7e, d5 may be smaller than d4 or d6. That is, the second set of eye insertion members can include an eye insertion member (730) in which the intervals between the plurality of rings are not constant.

[0093] However, as shown in FIG. 7e, the first set of eye insertion members not only includes an eye insertion member (730) in which the intervals (d4, d5, d6) between the rings of one eye insertion member (730) are not constant, but it is natural that the first set can also include a plurality of eye insertion members in which the intervals between the rings are constant but different from each other.

[0094] Referring to FIG. 7f, FIG. 7f shows an eyeball insertion member (740) including a plurality of connecting members arranged at the same angle from each other with respect to the center (C) and auxiliary connecting members (741 to 745) arranged at locations where the plurality of connecting members are not arranged. That is, the second set of eyeball insertion members can include an eyeball insertion member (740) including auxiliary connecting members arranged at locations where the plurality of connecting members are not arranged.

[0095] Taking FIGS. 7a to 7f together, the second set of eyeball insertion members (701, 702, 703, 704, 705, 706, 710, 720, 730, 740) includes at least one of the curvature of each eyeball insertion member, the eccentricity of the plurality of rings included in each eyeball insertion member, the distance from the center to the ring having the smallest size among the plurality of rings, the distance from the center to the ring having the largest size among the plurality of rings, the interval between the plurality of rings, whether the interval between the plurality of rings is constant, and the presence or absence of auxiliary connecting members arranged at locations where the connecting members are not arranged, and can include a plurality of eyeball insertion members that are different from each other. However, without being limited to the above-described examples, the second set of eyeball insertion members can include eyeball insertion members having more diverse patterns and shapes.

[0096] FIG. 8 is a flowchart illustrating a method of inserting an eyeball insertion member according to some embodiments. First, an eyeball insertion member to be inserted into the user's cornea can be selected (S810). At this time, an eyeball insertion member including a ring assembly including a plurality of rings having the same center and a plurality of connecting members connecting between the plurality of rings, wherein the plurality of rings have a concentric circular shape with different sizes from each other, and an eyeball insertion member including a ring assembly including a plurality of rings having the same center and a plurality of connecting members connecting between the plurality of rings, wherein the plurality of rings have the same eccentricity and have an elliptical shape with different sizes from each other, can be selected. However, it is not limited thereto.

[0097] Subsequently, a part of the cornea can be incised to create an incision (S820). At this time, a part of the cornea can be part or all of the corneal epithelial tissue, Bowman's membrane, corneal stroma, etc. among the constituent tissues of the cornea. A part of the cornea can be incised through a laser (e.g., femtosecond laser), a microkeratome (e.g., a microkeratome), or the like.

[0098] Before step (S820) is performed, pretreatment steps such as disinfecting the patient's eyelids and the surroundings and / or spreading and fixing the upper and lower eyelids with a speculum can be carried out first.

[0099] Subsequently, the selected eyeball insertion member can be inserted into the incision (S830). After step (S830), a step of wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0100] FIG. 9 is a flowchart illustrating a method of inserting an eyeball insertion member according to some embodiments. First, the corneal state of the incision portion where the eyeball insertion member is to be inserted on the user's cornea can be grasped (S910).

[0101] In some examples, the corneal state of the incision portion can include the curvature of the incision portion. For example, the corneal state of the incision portion can include the average spherical curvature or the average curvature of an ellipsoid, etc., but is not limited thereto.

[0102] In some other examples, the corneal state of the incision portion can include whether the thickness of the cornea is uniform. For example, the corneal state of the incision portion can include whether there are distinguishable thinner and thicker portions in the user's cornea. In some other examples, the corneal state of the incision portion can include the size, diameter, etc. of the user's cornea. However, without being limited to the foregoing examples, it is natural that the corneal state can include more diverse embodiments.

[0103] At this time, the corneal state of the incision part can be manually judged by a human, or grasped by using an eye scanner, a 3D scanner, and other medical imaging devices.

[0104] Subsequently, an eye insertion member corresponding to the grasped corneal state can be selected from among a plurality of eye insertion members (S920). In some examples, among the plurality of eye insertion members, an eye insertion member having the highest matching rate with the grasped corneal state in terms of shape, pattern, etc. can be selected. At this time, the matching rate can be manually judged by a human, or judged through a device, medical equipment, scanning device, etc. that utilizes a predetermined program.

[0105] The plurality of eye insertion members can include an eye insertion member in which a plurality of rings have a concentric circular shape, and / or an eye insertion member in which a plurality of rings have the same center but have an elliptical shape with different sizes.

[0106] In some examples, each eye insertion member of the plurality of eye insertion members is whether each ring of the eye insertion member is a circle or an ellipse, the curvature of each eye insertion member, the distance from the center to the ring having the smallest size among the plurality of rings, the distance from the center to the ring having the largest size among the plurality of rings, the interval between the plurality of rings, whether the interval between the plurality of rings is constant, the presence or absence of an auxiliary connecting member disposed at a location where the connecting member is not disposed, and when the plurality of rings have the same center but have an elliptical shape with different sizes, at least one of the eccentricities of the rings of each eye insertion member can be different from each other.

[0107] For example, the plurality of eye insertion members can include the first set of eye insertion members in FIGS. 6a to 6e described above, the second set of eye insertion members in FIGS. 7a to 7f described above, etc., but is not limited thereto, and the plurality of eye insertion members can include eye insertion members of more various embodiments.

[0108] That is, among the plurality of eye insertion members described above, for example, eye insertion members that differ from each other in terms of curvature, size, presence or absence of auxiliary connecting members, etc., by selecting an eye insertion member corresponding to the corneal state (e.g., curvature, uniformity of corneal thickness, corneal size, etc.) of the grasped incision part, an eye insertion member optimized for the corneal state of the user can be inserted.

[0109] At this time, by inserting an eye insertion member optimized for the corneal state of the user, it becomes possible to more firmly prevent the deformation of the cornea due to intraocular pressure, wrap and maintain the shape of the cornea, and also has a remarkable effect of being useful for more efficiently improving and maintaining the curvature of the cornea to a spherical or elliptical surface.

[0110] Subsequently, a part of the cornea can be incised to generate an incision part (S930). At this time, a part of the cornea can be a part or all of corneal epithelium, Bowman's membrane, corneal stroma, etc. among the constituent tissues of the cornea. A part of the cornea can be incised through a laser (e.g., femtosecond laser), a microkeratome (e.g., microkeratome), etc.

[0111] Before the step (S930) is performed, pretreatment steps such as disinfecting the patient's eyelid and the surroundings and / or spreading and fixing the upper and lower eyelids with a speculum can be carried out first.

[0112] Subsequently, the selected eye insertion member can be inserted into the incision part (S940). After the step (S940), a step of wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0113] Figures 10a to 10d are flowcharts illustrating an eye insertion method of an eye insertion member according to some embodiments and schematic diagrams for explaining the same. Referring to FIG. 10a, first, an eyeball insertion member to be inserted into the user's cornea can be selected (S1010). Here, step (S1010) can mean the same steps as step (S810) in FIG. 8 and / or steps (S910, S920) in FIG. 9, so detailed description is omitted.

[0114] Subsequently, in at least one part of the corneal constituent tissues, namely the corneal epithelium and Bowman's membrane, a groove having the same form as the form of the selected eyeball insertion member can be generated (S1020). At this time, the groove in at least one part of the corneal epithelium and Bowman's membrane can be generated through a laser or the like.

[0115] That is, by generating a groove having a form that matches the form of the selected eyeball insertion member (for example, curvature, size, presence or absence of an auxiliary connecting member, etc.) and inserting it accordingly, corneal removal can be minimized. At this time, since the form of the generated groove and the form of the inserted eyeball insertion member are the same, the side effect that the inserted eyeball insertion member bulges can be minimized.

[0116] Before step (S1020) is performed, pretreatment steps such as disinfecting the patient's eyelids and the surroundings and / or spreading and fixing the upper eyelid and lower eyelid with a speculum can be carried out first.

[0117] Subsequently, the selected eyeball insertion member can be inserted into the incision part (S1030). At this time, as described above, since the form of the generated groove and the form of the eyeball insertion member are the same, the eyeball insertion member can be inserted so as to fit into the generated groove. After step (S1030), a step of wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0118] Referring to FIG. 10b, first, an eyeball insertion member to be inserted into the user's cornea can be selected (S1040). Here, step (S1040) can mean the same steps as step (S810) in FIG. 8 and / or steps (S910, S920) in FIG. 9, so detailed description thereof will be omitted.

[0119] Subsequently, in at least one part of the corneal epithelial and Bowman's membrane among the constituent tissues of the cornea, a groove in an annular (Toric) form of a predetermined size can be generated (S1040). At this time, the annular form can include a general annular form, an elliptical annular form, and the like. The groove in at least one part of the corneal epithelial and Bowman's membrane can be generated through a laser or the like.

[0120] The generated groove in the annular form can be generated to have the same size as or a larger size than the size of the selected eyeball insertion member so that the eyeball insertion member can be inserted. Different from FIG. 10a, in FIG. 10b, by generating the groove in the annular form, a part of the cornea can be incised more conveniently.

[0121] The generated groove in the annular form will be described with reference to FIGS. 10c and 10d. FIG. 10c shows a schematic diagram of the generated groove in the annular form, and FIG. 10d shows a cross-sectional view of FIG. 10c.

[0122] Referring to FIGS. 10c and 10d, the generated groove (H) in the annular form and the boundary surfaces (Q1, Q2) of the groove (H) are shown. The selected eyeball insertion member can be inserted into the generated groove (H) in the annular form.

[0123] At this time, so that the selected eyeball insertion member can be inserted into the groove (H), the distance between the boundary surfaces (Q1) can be generated to be larger than the size of the minimum ring of the selected eyeball insertion member, and the distance between the boundary surfaces (Q2) can be generated to be larger than the size of the maximum ring of the selected eyeball insertion member.

[0124] Referring again to FIG. 10b, before step (S1050) is performed, pretreatment steps such as the step of disinfecting the patient's eyelid and the surrounding area and / or the step of spreading and fixing the upper and lower eyelids with a speculum can be carried out first.

[0125] Subsequently, the selected intraocular insertion member can be inserted into the incision (S1060). At this time, the selected intraocular insertion member can be inserted into an annular groove formed to a size larger than the selected intraocular insertion member.

[0126] After step (S1060), a step of wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0127] In the cases of FIGS. 10a and 10b, the process of generating grooves in the corneal epithelium and Bowman's membrane instead of the corneal stroma is illustrated. Thereafter, when removing the intraocular insertion member, since the corneal epithelium has the property of restoring to its original state, the process of removing the intraocular insertion member may be easier compared to the case where a groove is generated in the corneal stroma.

[0128] That is, when removing the intraocular insertion member inserted into the corneal stroma, since the corneal stroma does not have the property of restoring, an additional incision process (for example, incising the part excluding H so that the height of H matches the height of Q1 and Q2 in FIG. 10d) to make the heights of the incision part (groove, for example, H in FIG. 10d) and the non-incised part (for example, Q1, Q2 in FIG. 10d) coincide may be required. However, when incising the corneal epithelium, there is an effect that such an additional incision process is not necessary.

[0129] However, different from what is shown in FIGS. 10a and 10d (steps 1020, 1050), grooves having the same form as the form of the intraocular insertion member and / or annular grooves can also be formed through the corneal stroma and Bowman's membrane to the corneal stroma.

[0130] FIGS. 11a to 11b are a flowchart illustrating a method of inserting an intraocular member according to some embodiments and a schematic diagram for explaining the same. First, an intraocular member to be inserted into the user's cornea can be selected (S1110).

[0131] Here, step (S1110) can mean the same steps as step (S810) of FIG. 8 and / or steps (S910, S920) of FIG. 9, so detailed description is omitted.

[0132] Subsequently, among the constituent tissues of the cornea, the corneal stroma can be incised in a straight line in the horizontal direction to form an upper corneal stroma and a lower corneal stroma (S1120). FIG. 11b shows an example of the upper corneal stroma (1140) and the lower corneal stroma (1150) formed by incising in a straight line in the horizontal direction. At this time, the corneal stroma can be incised in a straight line in the horizontal direction using a laser (for example, a femtosecond laser), a microkeratome (for example, a microkeratome), or the like.

[0133] Before step (S1120) is performed, pretreatment steps such as disinfecting the patient's eyelids and the surroundings and / or spreading and fixing the upper and lower eyelids with a speculum can be performed first.

[0134] Subsequently, the selected intraocular member can be inserted into the incision (S1130). At this time, the selected intraocular member can be inserted between the upper corneal stroma and the lower corneal stroma, for example, at the position of the arrow in FIG. 11b.

[0135] After step (S1130), steps such as suturing the upper corneal stroma and the lower corneal stroma and wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0136] As shown in FIGS. 11a and 11b, when an eyeball insertion member is inserted between the upper and lower corneal stroma after making a horizontal linear incision in the corneal stroma, it is not necessary to separately create a groove having the same form as that of the eyeball insertion member and / or an annular groove. Therefore, the insertion of the eyeball insertion member into the eye is easier and more convenient. Further, since it is not a process of creating a groove in the corneal stroma, i.e., a process of excavating a part of the corneal stroma, there is an effect that the corneal stroma having non-restorable properties can be removed to a minimum. In addition, when removing the inserted mesh ring, after making a horizontal linear incision, the eyeball insertion member can be removed, and there is an advantage that the removal process is easy.

[0137] FIGS. 12a and 12b are flowcharts illustrating a method of inserting an eyeball insertion member according to some embodiments. Referring to FIG. 12a, first, an eyeball insertion member to be inserted into the user's cornea can be selected (S1210). Here, step (S1210) can mean the same steps as step (S810) of FIG. 8 and / or steps (S910, S920) of FIG. 9, and thus detailed description thereof is omitted.

[0138] Subsequently, among the constituent tissues of the cornea, the corneal stroma can be incised in a horizontal straight line to form an upper corneal stroma and a lower corneal stroma (S1220). Here, step (S1220) can mean the same step as step (S1120) of FIG. 11a, and thus detailed description thereof is omitted. Subsequently, a groove having the same form as that of the selected eyeball insertion member can be created in the lower corneal stroma (S1230). At this time, the groove in the lower corneal stroma can be created through a laser or the like.

[0139] That is, by creating a groove having a form that matches the form of the selected eyeball insertion member (for example, curvature, size, presence or absence of an auxiliary connecting member, etc.) and inserting it accordingly, it is possible to minimize the side effect that the eyeball insertion member bulges after insertion.

[0140] Subsequently, the selected member for insertion into the eyeball can be inserted into the incision (S1240). At this time, as described above, since the shape of the generated groove and the member for insertion into the eyeball are the same, the member for insertion into the eyeball can be inserted so as to fit into the generated groove.

[0141] After step (S1240), steps such as suturing the upper corneal stroma and the lower corneal stroma, and wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0142] Referring to FIG. 12b, first, a member for insertion into the eyeball to be inserted into the user's cornea can be selected (S1250). Since step (S1250) can mean the same steps as step (S810) in FIG. 8 and / or step (S910, S920) in FIG. 9, detailed description thereof is omitted.

[0143] Subsequently, among the constituent tissues of the cornea, the corneal stroma can be incised in a straight line in the horizontal direction to form the upper corneal stroma and the lower corneal stroma (S1260). Since step (S1260) can mean the same step as step (S1120) in FIG. 11a at this time, detailed description thereof is omitted.

[0144] Subsequently, a groove in an annular form of a predetermined size can be generated in the lower corneal stroma (S1270). At this time, the annular form can include a general annular form, an elliptical annular form, etc. The groove in the lower corneal stroma can be generated through a laser or the like.

[0145] The generated groove in the annular form can be generated to have the same size as or a larger size than the size of the selected member for insertion into the eyeball so that the member for insertion into the eyeball can be inserted. Different from FIG. 12a, in FIG. 12b, by generating a groove in the annular form, a part of the cornea can be incised more conveniently.

[0146] Subsequently, the selected eye insertion member can be inserted into the incision portion (S1280). At this time, the selected eye insertion member can be inserted into an annular groove formed to a size larger than the selected eye insertion member.

[0147] In the cases of FIGS. 12a and 12b, by adding the step of forming a groove (e.g., a groove having the same form as the eye insertion member or an annular groove having a predetermined size) in the lower stroma of the divided corneal stroma, there is an effect that the bulging phenomenon of the inserted eye insertion member can be reduced as compared with FIGS. 11a and 11b.

[0148] FIG. 13 is a flowchart illustrating a method of inserting an eye insertion member according to some embodiments. First, an eye insertion member to be inserted into the user's cornea can be selected (S1310).

[0149] Here, since step (S1310) can mean the same steps as step (S810) in FIG. 8 and / or steps (S910, S920) in FIG. 9, detailed description thereof is omitted.

[0150] Subsequently, a part of the cornea can be incised to form an incision portion (S1320). At this time, step (S1320) can include at least one of the steps of incising the corneal stroma in a horizontal straight line to form an upper corneal stroma and a lower corneal stroma and forming a groove in the lower corneal stroma among the constituent tissues of the cornea. The step of forming a groove in the lower corneal stroma can include the step of forming a groove having the same form as the selected eye insertion member in the lower corneal stroma, or the step of forming an annular groove having a predetermined size in the lower corneal stroma.

[0151] Step (S1320) can be performed using a laser (e.g., a femtosecond laser), a microkeratome (e.g., a microkeratome), or the like. Before the step (S1320) is performed, pretreatment steps such as a step of disinfecting the patient's eyelids and the surroundings and / or a step of spreading and fixing the upper and lower eyelids with a speculum can be performed first.

[0152] Subsequently, the selected eye insertion member can be inserted into the incision (S1330). According to some embodiments, at this time, the eye insertion member can be inserted between the upper corneal stroma and the lower corneal stroma, into a groove having the same form as the eye insertion member formed in the lower corneal stroma, or into a groove having an annular form with a predetermined size formed in the lower corneal stroma.

[0153] Subsequently, the incision can be sutured (S1340). At this time, the upper corneal stroma and the lower corneal stroma can be sutured. According to some embodiments, the upper corneal stroma and the lower corneal stroma can be crimped using a suture or the like.

[0154] After the step (S1340), a step of wearing a contact lens to protect the cornea while the corneal epithelium recovers can be performed.

[0155] The insertion steps of each eye insertion member in FIGS. 8 to 13 can be performed by a human and / or advanced by automated medical devices, eye insertion devices, surgical robots, or the like.

[0156] The above description merely exemplarily explains the technical idea of this embodiment. For those with ordinary knowledge in the technical field to which this embodiment belongs, various modifications and variations are possible without departing from the essential characteristics of this embodiment. Therefore, this embodiment is not intended to limit the technical idea of this embodiment but to explain it, and the scope of the technical idea of this embodiment is not limited by such an embodiment. The protection scope of this embodiment should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of rights of this embodiment.
