BACKGROUNDCorneal implants, such as corneal onlays and corneal inlays, can be small, delicate medical devices that need to be protected from damage or loss during storage and/or when preparing them for positioning onto corneal tissue. A need still exists for safe and efficient storage and/or positioning devices and methods that will prevent damage to, or loss of, the corneal implant and that can make it easy to prepare the corneal implant for use. The disclosure herein addresses one or more of these concerns.
SUMMARY OF THE DISCLOSUREOne aspect of the disclosure is an ophthalmic lens storage apparatus, comprising a lens applicator comprising a lens applicator member adapted to position the ophthalmic lens onto tissue; and a base comprising a lens applicator guide and a lens support member, the lens applicator guide configured to receive and stably interface with the lens applicator, wherein the lens applicator member and the lens support member are configured such that, when the lens applicator is positioned in the lens applicator guide, the ophthalmic lens is secured between the lens applicator member and the lens support member.
In some embodiments the lens applicator guide has a sectional shape, such as a partial hexagon, that is at least partially complimentary to a sectional shape of a lens applicator shaft, such as a hexagon. The lens applicator shaft sectional shape can be a polygon, and the lens applicator guide sectional shape can be at least partially polygonal, with fewer sides than the lens applicator shaft polygon shape.

The disclosure relates to devices for one or more of packaging, storing, positioning, and delivering corneal implants such as corneal inlays. The devices herein can be used in the movement and positioning of any ophthalmic lens such as, for example without limitation, corneal onlays, corneal inlays, corneal replacements, and contact lenses.
The disclosure includes devices and methods of use that rely at least partially on surface tension of liquids to control the positioning and/or movement of a corneal implant. The devices can be used in the storage, packaging, movement, or delivering of the corneal implants. These approaches can be used when the corneal implant is made at least partially of hydrophilic material, such as a hydrogel.
Surface tension is the property of liquids that allows the surface of a body of liquid to resist external forces. It is what allows objects denser then water, such as small pins and certain insects, to float on a liquid's surface. Surface tension is caused by the cohesive forces of a liquid's molecules. Cohesive forces are the attractive forces between two like molecules. As shown in
Adhesive forces, on the other hand, are those seen between unlike molecules. For some material combinations, these forces can be greater than the cohesive forces of a liquid's molecules. These strong adhesive forces are the cause of an upward ‘bowing,’ called the meniscus (as shown in
In the case of liquid suspended within a loop, as shown in
In the case of a solid, mesh, or other such surface, the adhesive and cohesive forces act in a similar fashion. Many factors, including the type of material, the type of fluid, and the surface geometry will affect the strength of the adhesive and cohesive forces.
Exemplary corneal implants that can be stored and used in the following embodiments are corneal inlays described in U.S. Pub. No. US 2007/0203577, filed Oct. 30, 2006, U.S. Pub. No. US 2008/0262610, filed Apr. 20, 2007, and U.S. Pub. No. 2011/0218623, filed Sep. 8, 2010, the disclosures of which are incorporated herein by reference. In some embodiments, a “small diameter” (i.e., between about 1 mm and about 3 mm) corneal inlay is made from a hydrogel, that may be primarily fluid. This, as well as the inlay's small size, causes it to behave in somewhat the same way as a fluid. The disclosure below makes use of these characteristics of the corneal implant and the adhesion forces between a fluid and various surface geometries. While the disclosure herein focuses on corneal inlays, any corneal implant that exhibits similar properties can be used as described herein. For example, corneal onlays, at least a portion of which have hydrophilic properties, can be used as described herein.
The devices herein rely on a body's “affinity” for a fluid or an object with fluid-like properties (e.g., a hydrophilic corneal implant). As used herein, a body's “affinity” for the fluid or fluid-like object is influenced by the difference between the strength of the net adhesive forces between the body and the fluid or fluid-like object and the strength of the net cohesive forces within the fluid or fluid-like object. In embodiments herein where there is a substantially constant fluid or fluid-like object (e.g., a hydrophilic corneal inlay), the relative affinities of two bodies for the fluid or fluid-like object is at least partially determined by the relative strengths of the net adhesive forces between the bodies and the fluid or fluid-like object. For example, in an embodiment in which the fluid-like object is a hydrophilic corneal implant, a first body can have a greater affinity for the implant than a second body when the net adhesive forces between the first body and the implant are greater than the net adhesive forces between the second body and the implant.
The corneal implant will remain adhered to the body with the highest net force (the sum of the adhesive and cohesive forces).
A first body, referred to herein as a “moderate body,” has a greater affinity for the fluid or fluid-like object than a second body, referred to herein as a “minimal body.” As used herein in this context, “body” may be used interchangeably with device, component, structure, or other similar term to indicate anything with structure. The eye, however, has a greater affinity for the fluid or fluid-like object than the moderate body. The different relative affinities can be used to handle the inlay and control the movement of the inlay as it is moved from one surface to another without a user needing to touch it with a hand or other tool. Factors that influence the relative affinities include one or more of: the type of material, the type of fluid, and the surface geometry including surface area.
As used herein, a corneal inlay (e.g., the fluid-like object) has a greater “affinity” for the corneal bed of the eye than it does the moderate body, and at the same time the inlay has a greater affinity for the moderate body than it does the minimal body. The eye can be described as having a greater affinity for the inlay than both the moderate body and the minimal body. Similarly, the moderate body can be described as having a greater affinity for the inlay than the minimal body. That is, the affinity between two bodies can be described relative to either body. That is, for example, the moderate body has a greater affinity for the inlay than does the minimal body, and thus the inlay will preferentially adhere to the moderate body over the minimal body.
In some embodiments the storage fluid is water or saline, for example. Water molecules are highly polarized, which provides for attractive forces with other materials.
A relative comparison of the affinity between each body and the inlay can be represented by: corneal tissue>moderate body>minimal body. The moderate and minimal bodies may take on many forms, including, without limitation, meshes, membranes, and/or material with different surface finishes or contours.
Due to the differences in affinity between the minimal body and the moderate body, the inlay preferentially remains adhered to the moderate body. It continues to adhere to the moderate body until exposed to a stronger adhesive force. The minimal and moderate bodies can therefore be any suitable material as long as the adhesive forces between the moderate body and the inlay are greater than the adhesive forces between the minimal body and the inlay. The moderate body has a greater affinity for the inlay than does the minimal body, and the adhesive properties of the materials is a factor influencing those affinities.
The distal end of apparatus 100 includes first portion 118 secured to moderate body 122. A second portion 120 is secured to minimal body 124 and is also detachably secured to first portion 118 around pin 134. The corneal implant (not shown in
As can be seen in
The depth of the recess is greater than the material thickness of the inlay, but is preferably slightly less than the height of the corneal implant in a non-stressed configuration. This ensures that at least a portion of the corneal implant is maintained in contact with both the moderate body and the minimal body. If at least a portion of the corneal implant is not in contact with the moderate body, the corneal implant can remain adhered to the minimal body rather than the moderate body when the moderate and minimal bodies are moved away from one another. In an exemplary embodiment the material thickness of the corneal implant is about 38.1 microns, the overall height of the implant in a non-stressed configuration is about 152.4 microns, and the depth of the recess is between about 63.5 microns and about 114.3 microns.
Similar to the embodiment in
In some exemplary embodiments of the systems shown herein (e.g., those in
In some exemplary embodiments of the systems shown herein (e.g., those shown in
In some embodiments the diameter of the minimal body is at least about 2 times the diameter of the moderate body. In some embodiments the diameter of the minimal body is at least about 1.5 times the diameter of the moderate body. In some embodiments the size of the plurality of hexagons in the minimal body is at least about 2 times the size of the plurality of hexagons in the moderate body. In some embodiments they could be at least about 3 times, or at least about 4 times.
In some embodiments the moderate body and the minimal body each have one or more openings, or apertures, extending through the bodies. The ratio of the moderate aperture perimeter (or sum of the aperture perimeters if more than one aperture) to the moderate aperture area (or sum of the apertures areas if more than one aperture) is greater than the ratio of the minimal aperture perimeter (or sum of the aperture perimeters if more than one aperture) to the minimal aperture area (or sum of the aperture areas if more than one aperture). Without necessarily wishing to be bound by a particular theory, the greater ratio results in greater forces being applied to the corneal implant from the moderate body than the minimal body, and thus provides the moderate body with a higher affinity for the corneal implant than the minimal body. When the moderate and minimal bodies are moved apart relative to one another, the greater forces applied to the implant will cause the implant to remain adhered to the moderate body rather than the minimal body.
By way of illustration only, in the embodiments shown in
Actuator assembly 316 includes push rod 320 coupled to button 321, and spring 322. Handle assembly 312 includes handle 324 coupled to distal portion 326, which includes the moderate body. The distal end of spring 322 is secured within the internal channel within handle 312, and the proximal end of spring 322 is secured to the distal end of button 321. Push rod 320 is configured to be disposed within the internal lumen of spring 322. As shown in more detail in
By incorporating rod 330, support assembly 314 rotates with respect to handle assembly 312 in only one direction, which prevents torquing.
In general, the recess in the minimal mesh body should be sized to prevent forces, or a substantial amount of forces, from being applied to the corneal implant while it is positioned in the nest between the moderate and minimal bodies prior to use.
The mesh apertures and the recess can be created by any suitable technique, such as chemical etching, laser cutting, micro water jet cutting, etc. In some instances chemical etching provides for a cleaner cut and does not require as much post-manufacture processing of the body. The mesh apertures can be created from only one side, or in some embodiments half of the thickness of the aperture is created from one side, while the other half of the aperture is created from the other side. In some embodiments the recess is etched from one side, while the mesh apertures are created in the other side. Any combination or variation on these techniques can be used. In some embodiments the recess is created by plunge electrical discharge machining (“EDM”).
In general, the net forces acting on the corneal implant are greater from the moderate mesh body than from the minimal mesh body. The polarity of water is an important factor when the corneal implant is formed of a hydrophilic material because in these instances the implant has properties like water and as such behaves like water. The dimensions of the mesh, configuration of the mesh, mesh body, and other factors can be modified to alter the relative affinities.
As described above, the minimal mesh body diameter is larger than the moderate mesh body diameter (both are shown to have a generally circular configuration). The minimal body diameter, due to its larger size, acts like a bumper, protecting the entire distal region of the apparatus during storage and use prior to actuation of the actuator. In the specific example shown above, the minimal body thickness is about twice as thick as the moderate body.
The moderate body diameter is larger than the recess, while the minimal body diameter is larger than the moderate body diameter. In some embodiments it may be helpful for the physician to be able to visualize the pupil when the corneal implant is being positioned in the cornea. For example, this may be desirable when implanting an inlay into the cornea wherein the inlay has a diameter less than the diameter of the pupil, such as a 1-3 mm diameter corneal inlay. For these applications the moderate mesh body can be sized such that it does not interfere with the visualization of the pupil. Specifically, the moderate mesh body portion is sized to allow the physician to be able to see the pupil during the delivery of the implant on corneal tissue. Starting with this constraint, the size of the other components can then be determined.
The use of “diameter” herein is not to suggest that the mesh body outer surfaces are perfectly circular or are circular at all. The two mesh portions could be square or rectangular-shaped, with the width and length of the minimal mesh portion larger than the width and length of the moderate mesh portion.
While in the embodiments above the implant's affinity for the moderate body is described as largely due to the size and configuration of the moderate mesh body relative to the minimal body, there are many ways to establish and control the implant's affinity for a given body. In some embodiments this can be accomplished by using a moderate body that is different than the minimal body. In some embodiments a finish could be applied to one or more of the surfaces of the moderate and minimal bodies. The finish can be different on the moderate and the minimal body to control the preferential adhesion. In some embodiments the moderate body has a better finish than the minimal body. In some embodiments the minimal body has a matte finish on it.
One or more components of the devices described herein can be a stainless steel or titanium. For example, applicator base 36 and applicator 34 can both be stainless steel, one can be titanium while the other is stainless steel, or both can be titanium.
Once the corneal implant is loaded in the apparatus between the moderate and minimal bodies, the implant can be used right away or it can be stored in packaging for any suitable period of time. When the corneal implant is made of a hydrogel material, it is important to keep the implant adequately hydrated during storage.
The following disclosure describes packaging tools and assemblies that are adapted to keep the corneal implant adequately hydrated during storage.
Embodiments herein describe both a moderate body and a minimal body. In some embodiments, however, the apparatus or its method of use need not include the minimal body. Without the minimal body, the corneal implant is not positioned within a corneal nest defined by the moderate and minimal bodies. The implant therefore need not be packaged with the moderate body. For example, it can be packaged in a separate packaging. In these embodiments the moderate body can utilize its preferential adhesion for the implant as set forth above to retrieve, or pick up, the corneal implant from its packaging. This can eliminate restrictions on how the corneal implant needs to be packaged. For example, the implant can be stored in a vial, free-floating in a storage medium. When the implant is ready to be positioned on the corneal tissue, the moderate body, which can be coupled to a handle, is positioned adjacent the implant in its storage medium, such as by scooping up the corneal implant into a position adjacent the apertures therein. Due to its preferential adhesion adaptation, the corneal implant will preferentially adhere to the moderate body. Once it has adhered to the moderate body, the implant is ready to be deposited onto the cornea as set forth above by relying on the moderate body's adaptation to allow the implant to preferentially adhere to the corneal tissue rather than the moderate body.
Storage apparatus 400 also includes clip 600, which is configured to stably interact with base 500 and lens applicator 900 to provide stability between lens applicator 900 and base 500 (described in more detail below).
Although not shown in
One of the benefits of base 500 and clip 600 is that they together provide stability to lens applicator 900 and secure it in place during storage periods. The configurations of the base and lens applicator are such that the lens applicator is prevented from rotating relative to the base, and the clip is configured to stably interface with the base and lens applicator to prevent the lens applicator from moving axially (i.e., up and down) relative to the base. The lens applicator is stabilized both rotationally and axially. This stabilizes the lens within the storage assembly and prevents it from escaping from the between the lens support member and the lens applicator member. When used herein, stable, stabilize, and secure do not necessary preclude any relative movement, simply that any movements are so minimal as to be inconsequential.
In this embodiment the lens support member and the lens applicator member define planes that are at slightly different angles relative to one another when in their stored positions, such as is shown in
The relative affinities of the lens applicator member (e.g., fine mesh, or moderate body) and the lens support member (e.g., course mesh, or minimal body) as described above apply to this embodiment as well.
As described above, shaft portion 902 is configured to be advanced into guide 504 of base and is further configured to be rotationally stabilized therein. In this embodiment shaft portion 902 has a hexagonal configuration, and five of its six surfaces are configured to be secured within the five surfaces of guide 504. Extension 604 on clip 600 is advanced into guide 912 in the lens applicator, which provides axial (i.e., up and down) stability to the lens applicator, while the configurations of the shaft portion 902 and guide 504 provide rotational stability to the lens applicator.
The shaft portion 1002 of handle can be configured in any number of ways. Distal end portion 1004 is configured to be secured to the shaft portion of lens applicator 900. In this embodiment distal end portion 1004 has opening 1006 at its distal end that extends proximally within end portion 1004 (see
It is important that after the user attempts to attach the handle to the lens applicator, the handle and lens applicator must not come apart. If the lens applicator separates from the handle, the lens applicator (to which the lens is adhered) could fall on the floor, the lens could be lost, etc. It is thus crucial that when a user attaches the handle, the handle and lens applicator stay together and do not come apart. One challenge in having the configuration of the opening 1006 and lens applicator shaft 902 the same is that the tolerances for the sizes of each are very small, possible making manufacturing more difficult. If the two components have the same outer surface configuration (e.g., two circular cross sectional shapes) it is easy for the two components to come apart. In this embodiment, to make sure the lens applicator and handle do not come apart, the lens applicator shaft 902 has a configuration that is different than the configuration of opening 1006. Specifically, lens applicator shaft 902 has a hexagonal configuration while the opening 1006 is circular (see
In this embodiment lens applicator shaft (which may be referred to herein as “pin”) includes an undercut 910 (see
As set forth above, the design of the handle and lens applicator provides for anti-rotation of the two shafts relative to each other, and provides user feedback to know the components are fully assembled.
While in this embodiment the lens applicator shaft is hexagonally shaped, other shapes can be used as well and still provide the anti-rotation benefits, such as triangular, square, octagonal, etc. Additionally, in other embodiments other types of undercuts may be used on the lens applicator shaft, such as a rounded profile instead of a sloping profile.
In use, once the handle is secured to the lens applicator, an optional step can be performed to help the corneal implant move towards, or become adhered to, the lens applicator member. After the clip has been removed and the top of the lens applicator member is exposed, an absorbent material is placed on top of the lens applicator member apertures, pulling fluid and the corneal implant towards the absorbent material and thus towards the lens applicator member apertures. This can help ensure that that the corneal implant will adhere to the lens applicator member when the handle and lens applicator member are lifted away from the lens support member and base.
One aspect of the disclosure is packaging that is configured to keep at least two of the storage assembly components stably interfaced in a secure relationship so that they do not disassociate from one another while housed in the packaging. As set forth above, two components can be stably interfaced but still move relative to one another.
Base 500 is also sized and configured to fit within inner chamber 1104 such that it does not move around to any noticeable degree relative to inner chamber 1104. This helps prevent the base, and thus the lens, from jostling or rattling about when in the inner chamber, which can prevent damage and reduce the likelihood that the lens escapes from between the base and the lens applicator. The inner chamber may be circular in cross section, however, so in fact the assembly could rotate within the inner chamber, but the clip would still be stably interfaced with the base and lens applicator in that situation.
