The holder / package can hold the device, for example, while measuring the device or performing a manufacturing process step and / or for packaging and shipping the device. In a preferred embodiment, the holder / package supports the device along the first and second haptic members of the device, and the optical member is not substantially in contact with the holder / package.

Description

本発明は、眼内レンズ等の光学レンズを保持および／または包装するための装置並びに方法に関する。具体的には、本発明は、１つ以上のハプティクス部材（haptics）によって相互接続された少なくとも２つの光学部材（optics）を有する遠近調節型眼内レンズ装置を安全に支持するためのホルダーおよび／またはパッケージ装置並びに方法に関する。   The present invention relates to an apparatus and method for holding and / or packaging an optical lens, such as an intraocular lens. Specifically, the present invention provides a holder for safely supporting a accommodation type intraocular lens device having at least two optics interconnected by one or more haptics and / or Or it relates to a packaging apparatus and method.

単一の光学部材を有する眼内レンズは長年知られ、用いられている。最近では、以下のFaezeh Sarfaraziによる米国特許および米国特許出願に、１つ以上のハプティクス部材によって相互接続された２つの光学部材を有する遠近調節型眼内レンズ装置が開示されており、その全体を参照することにより本願明細書に組み込む：
特許文献１「僅かな切開手術のための楕円形の遠近調節型眼内レンズ」、
特許文献２「シート材料で形成された遠近調節型レンズ」、
特許文献３「オープンチャンバー型の楕円形の遠近調節型眼内レンズ系」、および
２００３年５月２７日に出願された特許文献４「眼内レンズ用の型」。 Intraocular lenses having a single optical member have been known and used for many years. Recently, the following US patent and US patent application by Faezeh Sarfarazi disclosed a accommodation type intraocular lens device having two optical members interconnected by one or more haptic members, see in its entirety: Incorporated herein by reference:
Patent Document 1 “Elliptical accommodation lens for slight incision surgery”,
Patent Document 2 “Perspective adjustment lens formed of sheet material”,
Patent document 3 “Open chamber type elliptical accommodation type intraocular lens system” and Patent document 4 “Mold for intraocular lens” filed on May 27, 2003.

Sarfaraziの遠近調節型レンズ装置は、一方が負で他方が正の２つの光学部材を含み、目の空になった水晶体嚢内に配置される。これらの光学部材は、その周辺部に沿って、１つ以上のハプティクス部材によって相互接続され、これにより、光学部材は互いに離間され、眼内における装置の適切な配置が補助される。ハプティクス部材は、遠近調節を制御する目の毛様筋によって及ぼされる力に応答して撓み得るように、柔軟な材料で形成される。従って、装置に圧縮力が加わると、ハプティクス部材は撓んで更に径方向外側に弓状に湾曲し、これによって２つの光学部材が互いに引き寄せられて、目の遠近調節効果が達成される。毛様筋が弛緩すると、ハプティクス部材は（直線状の位置に向かって）反対方向に曲がることで光学部材の離間を広げ、レンズ装置は目を自然な非調節状態に戻す。   Sarfarazi's perspective lens system includes two optical members, one negative and the other positive, and is placed in a capsular bag with an empty eye. These optical members are interconnected along the periphery by one or more haptic members, which separate the optical members from each other and assist in proper placement of the device in the eye. The haptic member is formed of a flexible material so that it can flex in response to the force exerted by the ciliary muscle of the eye that controls accommodation. Therefore, when a compressive force is applied to the device, the haptic member bends and further bows radially outwards, thereby pulling the two optical members together and achieving the eye accommodation effect. As the ciliary muscle relaxes, the haptic member bends in the opposite direction (towards the linear position) to widen the separation of the optical member and the lens device returns the eye to its natural unadjusted state.

上述したように、単一の光学部材を有する眼内レンズは何十年も知られて用いられているが、２つのレンズを有する遠近調節型眼内レンズ装置は新しいものであり、まだ市場に出回っていない。尚、２つの光学部材を有するレンズ装置の製造、包装等の取り扱いには、単一の光学部材を有する眼内レンズの製造、包装等の取り扱いには存在しない問題がある。例えば、眼内レンズの設計および製造中に、装置に対して、装置が設計パラメータを達成していることを確実にするための特定の測定および処理が行われるであろう。光学面が互いにまたはホルダーの一部と接触すると精巧なレンズが損傷し得るので、このような測定および処理では、一般的に、装置の２つの光学部材をそれらの通常離間状態に保持する必要がある。同様に、２つの光学部材を有するＩＯＬ（眼内レンズ）の包装には、レンズの２つの光学部材が通常離間状態で保たれ、輸送および取り扱い中に振動や力が加わってもパッケージのどの部分とも接触しないことが必要である。

Not on the market. In addition, there exists a problem which does not exist in manufacture of an intraocular lens which has a single optical member, handling of packaging etc. in manufacture of a lens apparatus which has two optical members, packaging. For example, during the design and manufacture of an intraocular lens, certain measurements and processing will be performed on the device to ensure that the device is achieving design parameters. Such measurements and processes generally require that the two optical members of the device be held in their normally spaced state, since the delicate lenses can be damaged if the optical surfaces come into contact with each other or part of the holder. is there. Similarly, the packaging of an IOL (intraocular lens) having two optical members keeps the two optical members of the lens normally separated, so that any part of the package can be subjected to vibration or force during transportation and handling. It is necessary not to come into contact.

The holder / package includes a base and a plurality of spaced support pillars extending substantially perpendicularly from the base, the support pillars removably supporting the haptic member of the IOL device. The rear optical member and the front optical member normally extend in a free state from the haptic member and do not substantially contact the holder. In an advantageous embodiment, the holder acts as a package for storing the IOL device and shipping it to the surgeon while keeping the optical member spaced apart.

次に図面を参照すると、図１には、本発明と共に用いられ得る遠近調節型眼内装置１０の代表的な実施形態が示されている。簡単に説明すると、レンズ装置１０は、１つ以上の（好ましくは３つの）ハプティクス部材１６ａ、１６ｂおよび１６ｃによって相互接続された第１および第２の光学部材１２、１４を含み、ハプティクス部材１６ａ、１６ｂおよび１６ｃはそれぞれの間に３つの開放空間１８ａ、１８ｂ、１８ｃを画成する。ハプティクス部材１６ａ〜１６ｃは、光学部材の周囲１２ｐ、１４ｐよりも外側に湾曲した柔軟な部材であり、これにより、光学部材が光軸ｘ−ｘに概ね沿って互いに近づく方向および離れる方向に移動し得る。光学部材１２、１４は柔軟であるのが好ましく、例えばシリコーン等の任意の適切なＩＯＬレンズ材料で作られてよい。本発明はレンズ装置用のホルダー／パッケージであるので、本発明のホルダー／パッケージによって支持され得るレンズ装置の具体的な光学部材およびハプティクス部材の構成は、本願明細書に図示して説明する例示的なレンズとは異なっていてよいことを理解されたい。   Referring now to the drawings, FIG. 1 illustrates an exemplary embodiment of a accommodation type intraocular device 10 that may be used with the present invention. Briefly, the lens device 10 includes first and second optical members 12, 14 interconnected by one or more (preferably three) haptic members 16a, 16b and 16c, and the haptic members 16a, 16b and 16c define three open spaces 18a, 18b, 18c between each. The haptic members 16a to 16c are flexible members that are curved outward from the periphery 12p, 14p of the optical member, whereby the optical members move in a direction toward and away from each other substantially along the optical axis xx. obtain. The optical members 12, 14 are preferably flexible and may be made of any suitable IOL lens material, such as silicone. Since the present invention is a holder / package for a lens apparatus, the specific optical and haptic member configurations of the lens apparatus that can be supported by the holder / package of the present invention are exemplary illustrated and described herein. It should be understood that the lens may be different.

図２〜図７を参照すると、ホルダー／パッケージの好ましい実施形態が、全体を参照番号２０で示されて図示されている。ホルダー／パッケージ２０は、基部２２と、着脱自在カバー２４とを含み、これらはプラスチック等の任意の所望の材料で作られてよい。ホルダー／パッケージが、そこに保持されたレンズ１０の消毒用に用いられる場合には、ホルダー／パッケージ２０は、用いられる消毒方法に耐える材料で作られる必要がある。例えば、ＥＴＯによる消毒を用いる場合には、ＰＶＣ等のプラスチックが用いられ得る。   With reference to FIGS. 2-7, a preferred embodiment of the holder / package is shown generally designated by the reference numeral 20. The holder / package 20 includes a base 22 and a removable cover 24, which may be made of any desired material such as plastic. If the holder / package is used for disinfection of the lens 10 held therein, the holder / package 20 needs to be made of a material that can withstand the disinfection method used. For example, when using ETO disinfection, plastics such as PVC can be used.

好ましい実施形態では、ホルダー／パッケージの基部２２は、基部２２に対して略垂直に延びる第１および第２のレンズ支持部２６、２８を含む。支持部２６、２８は、後述する方法でレンズ１０を装着するのに十分な距離だけ離間されている。支持部２６、２８は様々な構成を有してよいが、好ましい形態では、底部２６ａ、２８ａおよび上部２６ｂ、２８ｂをそれぞれ有し、上部２６ｂ、２８ｂは各底部より小径に構成され、上部と底部との接合部に肩部２６ｃ、２８ｃが形成される。肩部２６ｃ、２８ｃは水平の棚状部を構成し、レンズ１０が支持部２６、２８に装着されると、ハプティクス部材１６ａおよび１６ｂの下向きの縁部が肩部２６ｃ、２８ｃ上に載置され得る。レンズ１０をホルダー／パッケージ２０に装着するには、図３および図４に示されるように、レンズ１０をまず支持部２６、２８の上方に位置させ、１つの下向きのハプティクス部材１６ｃが支持部２６、２８間にあり、ハプティクス部材１６ａ、１６ｂが支持部２６、２８の上方にそれぞれ位置合わせされた状態にする。次に、レンズ１０を基部２２に向かって降ろし、ハプティクス部材１６ａ、１６ｂを、支持部の上部２６ｂ、２８ｂを外側から覆うように通過させ、ハプティクス部材１６ａ、１６ｂの下向きの縁部１６ａ’、１６ｂ’が肩部２６ｃ、２８ｃにそれぞれ載置される状態にする。このレンズ１０の支持部２６、２８への完全装着位置が、図５および図６に示されている。この位置では、一番下のハプティクス部材１６ｃは、支持部２６、２８に接触しない状態で支持部２６、２８間に配置される。このハプティクス部材は、基部２２に接触しないのが更に好ましい。基部２２は、支持部２６、２８間の開口部２３を有してもよく、ハプティクス部材１６ｃは、そのサイズ設定および面取りした側部に起因して、少なくとも部分的に開口部２３を通って延出し、開口部の周囲に接触せずに自由に動く状態になってもよい（図４〜図７参照）。また、開口部２３は、消毒媒体（例えば、蒸気）が通過してレンズ１０に届くのを補助し得る。   In a preferred embodiment, the holder / package base 22 includes first and second lens supports 26, 28 that extend generally perpendicular to the base 22. The support portions 26 and 28 are separated by a distance sufficient to mount the lens 10 by a method described later. Although the support portions 26 and 28 may have various configurations, in a preferred form, the support portions 26 and 28 have bottom portions 26a and 28a and upper portions 26b and 28b, respectively, and the upper portions 26b and 28b are configured to have a smaller diameter than the respective bottom portions. Shoulder portions 26c and 28c are formed at the joint portion. The shoulder portions 26c and 28c constitute a horizontal shelf, and when the lens 10 is mounted on the support portions 26 and 28, the downward edges of the haptic members 16a and 16b are placed on the shoulder portions 26c and 28c. obtain. To attach the lens 10 to the holder / package 20, as shown in FIGS. 3 and 4, the lens 10 is first positioned above the support portions 26, 28, and one downward haptic member 16c is provided with the support portion 26. , 28 so that the haptic members 16a, 16b are aligned above the support portions 26, 28, respectively. Next, the lens 10 is lowered toward the base 22, and the haptic members 16a and 16b are passed so as to cover the upper portions 26b and 28b of the support portion from the outside, and the downward edges 16a ′ and 16b of the haptic members 16a and 16b are passed. 'Is put on the shoulders 26c and 28c. The complete mounting position of the lens 10 on the support portions 26 and 28 is shown in FIGS. In this position, the lowermost haptic member 16 c is disposed between the support portions 26 and 28 without contacting the support portions 26 and 28. More preferably, the haptic member does not contact the base 22. The base 22 may have an opening 23 between the supports 26, 28, and the haptic member 16c extends at least partially through the opening 23 due to its sizing and chamfered sides. It may be in a state of moving freely without touching the periphery of the opening (see FIGS. 4 to 7). The opening 23 can also assist the disinfection medium (eg, vapor) through and reaching the lens 10.

本願明細書では、２つのハプティクス部材１６ａ、１６ｂが支持部２６、２８を覆うように位置するものとして図示され説明されているが、この２つのハプティクス部材は、支持部２６、２８と係合する単一のハプティクス部材として形成されてもよいことを留意されたい。上述したように、本発明は、本願明細書に示すレンズ設計に限定されず、所望に応じて様々な構成の１つ以上のハプティクス部材を含んでよい。この点に関して、特に支持部上部２６ｂ、２８ｂは、そこに配置されるハプティクス部材の形状に適合するような任意の所望の形状および断面を有してよい。   In the present specification, the two haptic members 16a and 16b are illustrated and described as being positioned so as to cover the support portions 26 and 28. However, the two haptic members engage with the support portions 26 and 28. Note that it may be formed as a single haptic member. As described above, the present invention is not limited to the lens designs shown herein, and may include one or more haptic members of various configurations as desired. In this regard, in particular the upper support portions 26b, 28b may have any desired shape and cross section to match the shape of the haptic member disposed therein.

上述のようにレンズ１０が支持部２６、２８に装着されると、光学部材１２、１４はその通常離間位置に保たれ、ホルダー／パッケージ１２とは実質的に接触しない。図６に最もよく示されているように、支持部上部２６ｂ、２８ｂは、そこに装着されるハプティクス部材１６ａ、１６ｂの向かい合う面の形状により適合する形状を有してよい。具体的には、上部２６ｂ、２８ｂの外向きの面２６ｂ’、２８ｂ’は、ハプティクス部材１６ａ、１６ｂの内向きの面１６ａ’、１６ｂ’の曲率にそれぞれ沿うように湾曲していてもよい（図１も参照）。上述したように、支持部２６、２８の間隔は、本願明細書で実質的に図示され説明されたような、支持部２６、２８へのレンズ１０の装着を可能にするものである。この点に関して、ハプティクス部材１６ａ、１６ｂは、支持部上部２６ｂ、２８ｂと密に係合するのが好ましいが、過度にきつく係合するのではないことに留意されたい。従って、レンズ１０は、光学部材１２、１４が離間され基部２２に対して略垂直に位置する状態で、通常弛緩状態に保たれる。光学部材１２、１４およびハプティクス部材１６ａ〜１６ｃが支持部２６、２８に装着された際には、実質的に応力がかからない状態であるのが好ましい。   As described above, when the lens 10 is mounted on the supports 26, 28, the optical members 12, 14 are kept in their normally spaced positions and do not substantially contact the holder / package 12. As best shown in FIG. 6, the upper support portions 26b, 28b may have a shape that more closely matches the shape of the opposing surfaces of the haptic members 16a, 16b mounted thereon. Specifically, the outward surfaces 26b ′ and 28b ′ of the upper portions 26b and 28b may be curved so as to follow the curvatures of the inward surfaces 16a ′ and 16b ′ of the haptic members 16a and 16b, respectively ( (See also FIG. 1). As described above, the spacing between the support portions 26 and 28 allows the lens 10 to be mounted on the support portions 26 and 28 as substantially illustrated and described herein. In this regard, it should be noted that the haptic members 16a, 16b preferably engage closely with the support upper portions 26b, 28b, but not overly tightly. Therefore, the lens 10 is normally kept in a relaxed state in a state where the optical members 12 and 14 are spaced apart and positioned substantially perpendicular to the base portion 22. When the optical members 12 and 14 and the haptic members 16a to 16c are mounted on the support portions 26 and 28, it is preferable that stress is not substantially applied.

図２および図３に示されるように、レンズ１０が支持部２６、２８に装着されると、カバー２４が、レンズ１０および支持部２６、２８を覆うよう、基部２２に着脱自在に固定される。カバー２４はレンズ１０を保護するものであり、レンズ１０と実質的に接触しないのが好ましい。上部２５はスカート部２７に取り付けられて空間２９を構成し、カバー２４が基部２２に取り付けられると、レンズ１０および支持部２６、２８は空間２９内に配置される。空間２９は、レンズ１０および支持部２６、２８を収容するのに十分な大きさを有するが、取り扱い中または出荷中にレンズ１０が支持部２６、２８から不用意に外れるのを防止するために、十分に小さいものである。この点に関して、カバー２４が基部２２に結合された際には、上部２５の内面がハプティクス部材１６ａ、１６ｂの一番上の部分１６ａ”、１６ｂ”（図６）に近接し、これによって、ハプティクス部材が支持部２６ａ、２８ｂから外れる方向に付勢された場合にハプティクス部材の部分１６ａ”、１６ｂ”が当接するストッパとして作用する。   As shown in FIGS. 2 and 3, when the lens 10 is attached to the support portions 26 and 28, the cover 24 is detachably fixed to the base portion 22 so as to cover the lens 10 and the support portions 26 and 28. . The cover 24 protects the lens 10 and preferably does not substantially contact the lens 10. The upper portion 25 is attached to the skirt portion 27 to form a space 29, and when the cover 24 is attached to the base portion 22, the lens 10 and the support portions 26 and 28 are disposed in the space 29. The space 29 is large enough to accommodate the lens 10 and the support portions 26, 28, but to prevent the lens 10 from being inadvertently detached from the support portions 26, 28 during handling or shipping. It ’s small enough. In this regard, when the cover 24 is coupled to the base 22, the inner surface of the upper portion 25 is proximate to the top portions 16a ", 16b" (FIG. 6) of the haptic members 16a, 16b, thereby causing the haptics to When the member is urged in the direction away from the support portions 26a and 28b, the haptic member portions 16a "and 16b" act as stoppers against which they abut.

カバー上部２５は丸く、スカート部２７は円筒形であるのが好ましいが、その他の構成も可能である。上部２５および／またはスカート部２７には、消毒媒体が通過するための１つ以上の開口部２９ａ〜２９ｃが設けられてよい。スカート部２７の自由縁から下に延びる第１および第２のフィンガー部３１、３３の形態であり得る解除可能な結合手段がそれぞれ設けられ、これらは基部２２の支持部２６、２８より径方向外側に形成されたスロット３５、３７と協働する。図７に最もよく示されるように、カバー２４を基部２２に取り付ける際に、まず、フィンガー部３１、３３の自由端３１ａ、３３ａがスロット３５、３７を通って延出する。次に、フィンガー部の自由端３１ａ、３３ａがスロット肩部３５ａ、３７ａ（図５）とバヨネット式の結合で係合するまで、カバー２４を回転させる。カバー２４を取り外すには、カバー２４を反対方向に回転させて、フィンガー部とスロット肩部との係合が解除された時に、カバー２４を基部２２から持ち上げるだけでよい。当然ながら、他のタイプの着脱自在結合手段を用いてもよい。   The cover upper portion 25 is preferably round and the skirt portion 27 is preferably cylindrical, but other configurations are possible. The upper portion 25 and / or the skirt portion 27 may be provided with one or more openings 29a to 29c through which the disinfecting medium passes. Releasable coupling means, each of which may be in the form of first and second finger portions 31, 33 extending downward from the free edge of the skirt portion 27, are provided, which are radially outward from the support portions 26, 28 of the base 22.

The support portions 126 and 128 are separated from the wall portion 122b, and spaces 123 and 125 are formed therebetween. When the lens device 10 is mounted on the base 122 by passing the haptic members 16a and 16b so as to cover the periphery of the support portions 126 and 128, the haptic members 16a and 16b are placed in the spaces 123 and 125, respectively. The members 12, 14 are arranged in a relaxed spaced state. As best shown in FIG. 8b, the upper portions of the outward surfaces of the haptic members 16a and 16b gently abut against the wall portion 122b, and the bottom portions gently abut against the support portions 126 and 128, respectively. The device 10 is prevented from moving laterally along an axis that intersects the supports 126,128. In this manner, the base 122 captures the haptic member between the support portion and the wall portion, so that the optical members 12 and 14 are separated and arranged substantially perpendicular to the central circular portion 122a of the base portion. The lens device 10 is supported. The central circular portion 122a may include a through hole 122c for allowing the disinfecting medium to pass therethrough.
