Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to eye surgery, and more specifically, some embodiments can relate generally to systems, methods, and devices for inserting an intraocular lens (IOL) into an eye using a soft tip plunger. BACKGROUND

[0002] The human eye can suffer from many diseases, resulting in mild deterioration to complete loss of vision. While contact lenses and eyeglasses can compensate for some diseases, others can require ophthalmic surgery. Generally, ophthalmic surgery can be classified as posterior segment surgery, such as vitreoretinal surgery, and anterior segment surgery, such as cataract surgery. Vitreoretinal surgery can address many different eye conditions, including but not limited to macular degeneration, diabetic retinopathy, diabetic vitreous hemorrhage, macular hole, retinal detachment, epiretinal membrane, and cytomegalovirus retinitis.

[0003] For cataract surgery, the surgery can require making an incision in the eye and inserting a tool into the eye to replace the cloudy lens with an intraocular lens (IOL). An insertion tool can be used to deliver the IOL into the eye. As an example, the insertion tool can include a plunger for pushing the IOL out of a nozzle of the insertion tool. In some cases, the IOL can be pre-loaded into the insertion tool. In other cases, a separate carrier can be loaded into the insertion tool. The plunger can engage the IOL to advance the IOL from the carrier through the nozzle into the eye. The carrier (or insertion tool) can include a folding chamber configured to fold the IOL, for example, as the IOL advances through the folding chamber. In some cases, a separate action can cause the IOL to fold.

[0004] Delivering the IOL from the insertion tool can be a multi-step process. For example, the delivery can include two phases, which can be referred to as an advancement phase and a delivery phase. In the advancement phase, the IOL can be advanced from a storage position in the carrier to a dwell position. The IOL can be pre-folded or can fold as it is advanced from the storage position to the dwell position. At the dwell position, advancement of the IOL can be stopped, the nozzle is positioned in the eye, and then the IOL can be further advanced from the dwell position in the delivery phase, which can include advancing the IOL through the nozzle into the eye. SUMMARY

[0005] In an example embodiment, the present disclosure provides an apparatus for delivering an IOL into an eye. The apparatus includes a plunger and a plunger tip. The plunger tip includes a recess positioned at a distal end of the plunger tip. The plunger tip further includes a pocket in fluid communication with the recess.

[0006] In another example embodiment, the present disclosure provides an apparatus for delivering an IOL into an eye, the apparatus comprising a nozzle and a cartridge. The cartridge is coupled to the nozzle and a plunger is aligned with a bore of the cartridge. The plunger tip comprises a recess positioned at a distal end of the plunger tip. The pocket is in fluid communication with the recess.

[0007] In another example embodiment, the present disclosure provides a method for delivering an IOL into an eye. The method comprises inserting a nozzle of an insertion tool into an eye through an incision. The insertion tool further comprises a plunger and a plunger tip. The plunger tip comprises a recess positioned at a distal end of the plunger tip. The plunger tip further comprises a pocket in fluid communication with the recess.

[0008] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are intended to provide a further explanation of the present disclosure as claimed. In this regard, additional aspects, features, and advantages of the present disclosure will be apparent from the following detailed description. BRIEF DESCRIPTION OF DRAWINGS

[0031] To facilitate an understanding of the principles of the present disclosure, reference will now be made to the implementations illustrated in the drawings, and specific language will be used to describe the same. It will, nevertheless, be understood that no limitation of the scope of the disclosure is intended. Alterations and further modifications of the described devices, instruments, methods, and any further application of the principles of the present disclosure are fully contemplated as would normally occur to one skilled in the art to which the disclosure relates. In particular, it is fully contemplated that the features, components, and / or steps described with reference to one or more implementations can be combined with the features, components, and / or steps described with reference to other implementations. For the sake of simplicity, the same reference numbers will be used in the description of the same or like parts from figure to figure.

[0032] Some embodiments of the present disclosure provide improvements over existing soft tip plungers commonly found in manual loading IOL delivery systems. Prior soft tip plungers are solid cylinder “plug” type. These solid cylinder plunger tips can damage the IOL during the process of IOL delivery into the eye. For example, the solid cylinder plunger tip can squeeze the haptics and / or the trailing haptic during the compression and delivery of the IOL. Some embodiments described herein provide more advanced geometries to prevent damage to the IOL during delivery. In particular, some embodiments described herein include a soft tip of the plunger that includes a surface topography. The surface topography can include contours such as dimples and / or pockets to provide relief for the haptics and / or trailing haptic attached thereto when the IOL is compressed during delivery. This relief can prevent damage to the IOL.

[0033] Particular embodiments of the present disclosure relate to a plunger that can be packaged in a pre-loaded system for delivery of an IOL through an incision that can be less than 2.0 millimeters (“mm”) in diameter. The plunger is configured to engage and advance the IOL from a cartridge and deliver the IOL without damaging the IOL. Particular embodiments of the present disclosure include a rigid geometric base for improved IOL engagement and delivery. The base can be surrounded by a soft material or soft tip that provides sufficient cushioning to prevent damage to the IOL during delivery.

[0034] Figure 1 An IOL 10 according to some embodiments of the present disclosure is illustrated. The IOL 10 can be any suitable intraocular lens. The IOL 10 can include a lens portion 12 and a haptic extension 14. The haptic extension 14 can be side struts (or other suitable extensions) extending from the lens portion 12 that can stabilize the IOL 10 when it can be disposed within a patient’s eye. A haptic 16 can be a shoulder or portion of the lens portion 12 from which the haptic extension 14 extends. It will be appreciated that the IOL 10 can include other suitable components and / or features. Figure 1 The IOL 10 shown is merely exemplary, and the technology disclosed herein can be used with any suitable IOL. For example, a modular IOL (not shown) can also be used, which includes a lens portion that can be disposed in a base having a haptic extension.

[0035] Figure 2A and Figure 2B An insertion tool 32 for implanting an IOL 10 in an eye according to certain embodiments of the present disclosure is shown. It should be noted that the insertion tool 32 is a non-limiting example, and other types of insertion tools (e.g., manual or non-electrically powered tools) can be used with a soft tip plunger (e.g., shown) according to certain embodiments of the present disclosure. Figure 5A and Figure 5B As shown, the insertion tool 32 can include a housing 34. The housing 34 can generally be tubular, and can include a proximal or first end 35 opposite a distal or second end 41. A cable 36 that carries power and / or control signals from a separate user console (not shown) can extend from the first end 35. In certain embodiments, the insertion tool 32 can include a battery. Figure 2A

[0036] Figure 2B is a close-up view of the second end 41 according to certain embodiments of the present disclosure. As shown, the insertion tool 32 can also include a cartridge mount 37 that holds a detachably mounted insertion cartridge 38. According to exemplary embodiments, the insertion cartridge 38 can be a disposable polymer component adapted to contain an unfolded IOL 10 and to fold and displace the IOL 10 as the plunger is translated forward from the housing 34 and through the insertion cartridge 38.

[0037] The cartridge mount 37 can be a rigid member that extends from the second end 41. In some embodiments, the cartridge mount 37 can include a metal cutout or curved inner surface 37a that accommodates the insertion cartridge 38. In certain embodiments, an end 39 of the cartridge mount 37 can be press-fit into a passageway 40 that extends through the housing 34 and along the longitudinal axis L of the housing 34, as shown.

[0038] Figure 3 A partial cutaway view of an exemplary embodiment of the insertion tool 32 is shown, which illustrates an actuation assembly 44 disposed within the housing 34 (e.g., shown). Figure 2A The actuation assembly 44 can linearly translate a plunger 47 along the longitudinal axis L of the housing 34.

[0039] ​The actuation assembly 44 includes a shaft 46 configured to longitudinally translate within a threaded (female) tubular coupler 48. As shown, the shaft 46 can be coupled to a drive system 50 and a plunger 47. The plunger 47 can be removably coupled to the shaft 46 via a snap-fit mechanism 49. In some embodiments, the snap-fit mechanism 49 includes a portion 46a of the shaft 46 that interlocks with a portion 47a of the plunger 47. As shown, the portion 47a can be opposite a distal end 47b of the plunger 47. The drive system 50 can include components such as electric motors and gear sets configured to rotate the tubular coupler 48 to force the shaft 46 and plunger 47 to linearly translate within the tubular coupler 48. As shown, the tubular coupler 48 can engage a threaded (male) coupler 52 at a rear end of the shaft 46, thereby forcing the shaft 46 to linearly translate in response to activation of the drive system 50. An O-ring 54, which can be formed of an elastomer, can provide a seal between the housing 34 and the actuation assembly 44, thereby preventing moisture and / or other contaminants from reaching an interior of the housing 34.

[0040] Figure 4 A partial cross-sectional view of an insertion cartridge 56 is shown in accordance with certain embodiments of the present disclosure. The insertion cartridge 56 can be similar to the insertion cartridge 38 (e.g., Figure 2B shown). Figure 4 A plunger 58 is also shown in accordance with certain embodiments of the present disclosure that can be similar to the plunger 47 (e.g., Figure 3 shown). The plunger 58 can include a portion 60 that is similar to the portion 47a (e.g., Figure 3 shown). It should be noted that the plunger 58 is a non-limiting example and other types of plungers can be used. As shown, the portion 60 can include features such as a groove 62 and a recess 64. The portion 46a of the snap-fit mechanism 49 (e.g., Figure 3 shown) includes features that are complementary or corresponding to the groove 62 and the recess 64 to secure or “snap” the portion 46a and the portion 60 together. As shown, a nozzle 66 can be positioned at a distal end of the insertion cartridge 56.

[0041] Figure 5A A perspective view of the plunger 58 with a soft tip 70 is shown in accordance with certain embodiments of the present disclosure. The soft tip 70 can be disposed at a distal end 72 of the plunger 58 (e.g., as Figure 6 shown). In some embodiments, the soft tip 70 can be overmolded onto the distal end 72. In some embodiments, the soft tip 70 can be adapted to provide a cushioned or non-abrasive engagement with the IOL 10, for example, as compared to the distal end 72. The soft tip 70 can include a smooth surface(s) and can be elastic. In certain embodiments, the soft tip 70 can be formed of silicone.

[0042] The soft tip 70 can be made of any suitable medical grade flexible soft material. Without limitation, the soft tip 70 can be made of styrene block copolymer, polyolefin blend (“TPO”), elastomeric alloy, thermoplastic polyurethane (“TPU”), thermoplastic copolyester, thermoplastic polyamide, or a combination thereof. The plunger 58 can be made of polystyrene, acrylonitrile-butadiene-styrene, polycarbonate, polyamide, polyimide, polyetherimide, polyarylamide, polyether ether ketone, polybutylene terephthalate, polypropylene, polysulfone, liquid crystal polymer, or a combination thereof. In some embodiments, the material forming the soft tip 70 can have a Shore A durometer value of about 30 to about 95. As used herein, the durometer value is the Shore hardness value measured using ASTM D2250 Type A and Type D scales.

[0043] Figure 5B A perspective view of a plunger 59 having a distal end 73 according to certain embodiments of the present disclosure is shown. The plunger 59 can include an elongated base 75 extending from a connector 77 for connecting the plunger 50 to an insertion tool, such as the insertion tool 32. The plunger 59 can include a channel 79 to facilitate actuation of the plunger 59 from, for example, the housing 34 of the insertion tool 32. In some embodiments, the plunger 59 can include features similar to the plunger 58. For example, the plunger 59 can be made of polycarbonate. Additionally, the distal end 73 can be similar in certain respects to the distal end 47b. A soft tip 81 (see, e.g., FIG. 6) that can be overmolded onto the distal end 73 is described in further detail below. Figures 7D to 7F ).

[0044] Figure 5C A cross-section of the plunger 59 according to certain embodiments of the present disclosure is shown. The cross-section is taken along the dashed line extending from A to A’ as shown in Figure 5B . As shown in Figure 5C , the plunger 59 can include a width (w2) and a height (h2) as shown. The channel 79 can be curved and include a radius of curvature r2 ranging from 1 mm to 2 mm (e.g., 1.25 mm to 1.35 mm).

[0045] Figure 6 A cross-section of the insertion cartridge 56 taken along the dashed line LI as shown in Figure 4 is shown. As shown in Figure 6 , the plunger 58 can be movably (e.g., axially movably) disposed within the insertion cartridge 56. The nozzle 66 can include a passageway 67 extending from a distal end of the nozzle 66 to an inner chamber or cradle 68 of the insertion cartridge 56. The passageway 67 can include a fold chamber 69 including a diameter that tapers inwardly as shown. The tapering can facilitate bending or folding of the IOL 10 during the process of the IOL 10 passing through the nozzle 66 and being delivered into the eye.

[0046] Figure 7A A side perspective view of a soft tip 70 according to certain embodiments of the present disclosure is shown. The overall length L of the soft tip 70 can range from about 2 mm to about 6 mm. As shown, the distal end 70a (and its surface) includes a recess or pocket 74 that can have a radius of curvature R ranging from about 0.4 mm to about 0.8 mm (e.g., about 0.65 mm).

[0047] In certain embodiments, when the IOL 10 is compressed during delivery (e.g., as shown), the pocket 74 can receive a gusset of the trailing haptic extension (e.g., gusset 16b as shown) and can guide the gusset into a recess 76 that can be adjacent to or in fluid communication with the pocket 74. The recess 76 can include a depth d ranging from about 1 mm to about 4 mm (e.g., about 2.5 mm). In some embodiments, the recess 76 can occupy about 20% to about 30% (e.g., about 25%) of the distal end 70a, as shown. Figure 10B Figure 10B

[0048] Figure 7B is a front perspective view of a soft tip 70 according to certain embodiments of the present disclosure. The pocket 74 can be positioned at the center of the distal end 70a. The distal end 70a can have a diameter (indicated by dashed line d2) of about 2 mm or less, e.g., ranging from about 1 mm to about 2 mm (e.g., about 1.6 mm), to allow insertion into a cutout of less than 2 mm. The height h and width w of the recess 76 can range from about 0.5 mm to about 1.5 mm (e.g., about 1.3 mm).

[0049] Figure 7C shows a longitudinal cross-section of a soft tip according to some embodiments of the present disclosure of Figure 7A In certain embodiments, the soft tip 70 can include a passageway 71 extending from an opening 71a positioned at the back of the soft tip 70, as shown. The passageway 71 can have an inner diameter of about 2 mm or less, e.g., ranging from about 0.5 mm to less than about 2 mm. The distal end 72 of the plunger 58 (e.g., as shown) can be secured within the passageway 71 via, e.g., a press fit. Figure 6

[0050] Figure 7D shows a side view of a distal end 73 according to some embodiments of the present disclosure of Figure 5B As shown, the distal end 73 includes a recess 81 for attachment to a soft tip (e.g., soft tip 86 as shown). Figure 7F

[0051] Figure 7E ​​​​A cross-section of the distal end 73 according to certain embodiments of the present disclosure is shown. The cross-section is taken along the dotted line extending from B to B', as shown. Figure 7D As shown, the distal end 73 includes a recess 83. The recess 83 can include a first portion 85 and a second portion 87 extending at an angle from the first portion 85. For example, the second portion 87 can extend at an angle of about 30° to about 60° (e.g., 45°) from the first portion 85.

[0052] Figure 7F A side view of a soft tip 86 that can be overmolded onto the distal end 73 of the plunger 59 according to certain embodiments of the present disclosure is shown. The soft tip 86 can be similar to the soft tip 70. For example, the soft tip 86 can include a pocket 91 in fluid communication with the recess 88. The soft tip 86 can include a thickness of at least 0.1 mm (e.g., overmold thickness of silicone or TPU). The soft tip 86 can include dimensions similar to the soft tip 70.

[0053] Figure 8 is a front perspective view of the nozzle 66 according to certain embodiments of the present disclosure. As shown, the soft tip 70 can be visible in the opening 78 of the nozzle 66. The pocket 76 of the soft tip 70 can be aligned with the upper right quadrant 78a of the opening 78 of the nozzle 66, as shown. The diameter of the opening 78 can be about 2 mm or less, for example ranging from about 1 mm to about 2 mm.

[0054] Figure 9A and Figure 9B is a cross-section of the insertion tool 32 according to certain embodiments of the present disclosure. The cross-section shows a side view taken along the dotted line L2, for example as shown in Figure 2A .

[0055] Figure 9A An insertion tool 32 with a plunger 58 according to certain embodiments of the present disclosure is shown. As shown, the plunger 58 is retracted and positioned within the insertion tool 32. In this initial position, an IOL 10 can be positioned in the cradle 68 of the insertion cartridge 56 prior to the advancement stage. The IOL 10 can include the IOL 10 or components thereof.

[0056] Figure 9BAn insertion tool 32 in an advancing stage according to certain embodiments of the present disclosure is shown. As shown, a plunger 58 can extend from a housing 34 and can enter a cradle 68, via a dwell position into a deployment channel 80 that can advance an IOL 10 through a folding chamber 69 to a nozzle 66. As the IOL 10 passes through the folding chamber 69, the IOL 10 can fold (compress) in the folding chamber 69. The IOL 10 can roll up or fold to reduce the size of the IOL 10. This reduction in size allows the IOL 10 to be delivered through a minimum size incision in the eye (e.g., less than 2.0 mm).

[0057] Figure 10A and Figure 10B is a cross-section of a top view of an insertion cartridge 56 according to certain embodiments of the present disclosure.

[0058] Figure 10A A plunger 58 is shown encountering an IOL 10 disposed within a cradle 68. The plunger 58 moves in the direction indicated by the arrow. The plunger 58 can move through the cradle 68 via a bore 56a of the insertion cartridge 56, as shown. The plunger 58 contacts and moves the IOL 10 through a folding chamber 69 for delivery. The bore 56a can be aligned with the plunger 58.

[0059] Figure 10B A plunger 58 is shown driving an IOL 10 from a cradle 68 through a folding chamber 69 to a deployment channel 80, as shown. A recess 74 can contact a lens portion 12 and / or a haptics 16a of the IOL 10. A pocket 76 receives the haptics 16a, providing relief for the haptics 16a. This relief can reduce the bending of the haptics 16a, preventing damage to the IOL 10. A radius of curvature R (shown in Figure 7A may allow the distal end 70a to grab the IOL 10 and allow the IOL 10 to rotate and compress to position the haptics 16a in the pocket 76, as shown.

[0060] In a deployment stage, the insertion tool 32 can advance the IOL 10 from the dwell position and out of the nozzle 66 via the deployment channel 80 into the patient’s eye.

[0061] An exemplary technique for implanting an IOL 10 into a patient’s eye 90 will now be described with reference to Figure 11A and Figure 11B

[0062] As shown in Figure 11A , an insertion tool 89 can be similar to an insertion tool 32 according to certain embodiments of the present disclosure (e.g., as shown in Figure 2A ​A surgeon can form an incision 92 in the eye 90. For example, the incision 92 can be formed through the sclera 94 of the eye 90. The incision 92 can be a suitable width or length. Without limitation, a suitable width and / or length can be less than 2 millimeters. After the incision 92 is formed, the nozzle 66 of the insertion tool 89 can be inserted through the incision 92 into an interior portion 96 of the eye 90. The insertion tool 89 can be actuated to dispense the IOL 10 into a capsular bag 98 of the eye 90.

[0063] The IOL 10 can be delivered in a folded (or rolled up configuration) and allowed to unfold after being ejected from the insertion tool 32. After being dispensed, the IOL 10 should unfold and seat within the capsular bag 98 of the eye 90, as shown. Figure 11B The haptic extensions 14 can be manipulated, for example, to engage with the paraequatorial region of the capsular bag 98. The haptic extensions 14 can engage the capsular bag 98 to secure the IOL 10 in the capsular bag 98.

[0064] Using the methods and systems described herein can provide a number of benefits and advantages compared to other IOL delivery systems. For example, as described herein, the soft tip 70 includes a geometry that prevents or mitigates damage to the IOL 10 when compressed during delivery into the eye.

[0065] It is believed that the operation and construction of the present disclosure will be apparent from the foregoing description. While the apparatus and method shown or described above have been characterized as being preferred, various changes and modifications can be made therein without departing from the spirit and scope of the present disclosure as defined in the following claims.
