Abstract

一种多焦眼镜片包括第一和第二镜片构件。每个镜片构件都具有一个光滑的外表面和一个带有一个环绕其周边的边缘的内表面。至少在一个镜片构件上有一个多焦衍射波带板，其特性由折射率表示。用超声焊接将这二个构件在边缘处焊接在一起，形成一个紧贴衍射波带板的镜腔。镜腔里充以折射率与衍射波带板不同的液体药物。一个穿过其中一个镜片构件的小孔起着液体传送机构的作用，可以在镜腔和眼睛之间传送药物。

Description

本发明与一些多焦衍射眼镜片有关。
矫正视力的眼镜片可以做成许多种具体形式。可能最常见的是接触式镜片和外科植入眼内的镜片。其它眼镜片还有人工角膜和板内植入片。在许多美国专利中发明了一些具有单一焦距的眼镜片，这些镜片用来矫正只在一个普通的距离范围内发生的视力问题（如近视或远视）。
卡尔曼（Kelman）的美国专利4，828，558发明了一种用一对具有相对的内表面的薄片状构件制成的复合镜片。至少其中一个构件的内表面上有一个受到防护的菲涅尔（Fresnel）镜片。这二个内表面封在一起形成一些封有气体而无液体的空隙。这些空隙的折射率与这二个构件的折射率不同，菲涅尔镜片由一系列接连着的同心环组成，利用折射原理进行所需的光学矫正。
斯托爱等人（Stogetal）的美国专利4，731，078发明了一种由内层和外层所形成的眼镜片。内层可以用充有气体或液体的镜腔来形成。或者说，内层可以具有一个可以是所充气体的菲涅尔式的界面。
日常活动（如驾驶或阅读）要求无论对远距或近距都能得到清晰的视觉景象。健康人的眼睛可以根据景象的范围通过肌肉使眼的柔性透镜变形来改变焦距，不幸的是随着年龄的增大眼睛对不同距离景象的适应能力通常减弱。对于那些经外科植入替用镜片的人来说通过肌肉使镜片变形适应多种焦距的能力也受到限制。因此，在要求对近视和远视都能得到矫正时就要使用具有几个予定焦距的多焦透镜。
霍夫曼（Hofmnn）的英国专利1，154，360发明了一种多焦菲涅尔透镜。在一个实例中，这种菲涅尔透镜做在一个与充有气体的间隙贴邻的内表面上。
在一些眼镜片中也使用了衍射波带片，这在库 邯（Cohen）的美国专利4，210，391、4，338，005和4，340，283中有所披露。这些镜片应用衍射原理提供光学放大率。一组同心圆环区将光聚至多个焦点。没有聚焦的象对聚焦的象没有影响。
海哥钦（Higuchi）的美国专利3，630，200发明了一种适用于眼睛的插入物。这种插入物放在眼球和眼睑之间，可以在很长一段时期内给眼不断上药。这种插入物可以用一个含有药物的内核和一个柔软的亲水外层制成。
泰亨（Tahan）的英国专利申请出版物2，171，106披露了一种用于接触式和眼内镜片的用水凝胶制成的聚合物。要注意的是，这种聚合物可以做成用于眼睛的绷带式镜片，诸如抗生素之类的药物可以被装入到这镜片内，逐渐渗入眼睛。
高质量的视力对往大多数的人来说至关紧要。然而，对远距和近距都需矫正的弱视情况是比较常见的。因此，历来就希望对多焦眼镜片加以改进。这种类型的镜片必需能对视力进行精确的矫正，在生理上其长期舒适性也应该可与人眼比美，并且使用方便。
本发明提供一种与人眼生理高度比美的多焦眼镜片。这种镜片包括第一透镜构件和第二透镜构件，每个构件都有一个光滑的外表面和一个围绕其周边有一个边缘的内表面。在第一透镜构件的内表面上加工出一个多焦衍射波带板，其特性由一个折射率来表示。这二个镜片构件的边缘被牢固地接合在一起。形成了一个由内表面限定的紧贴衍射波带板的镜腔。这镜腔的特性由一个与衍射波带板的折射率不同的折射率来表示。
这种镜片的一个具体实例是用超声焊接将二个镜片构件的边缘焊接在一起，而另一个实例则是用粘合剂粘合边缘。
这种透镜的再一个实例是在镜腔中充有液体药剂。诸如穿过一个透镜构件的小孔那样的输液机构可以在小腔和眼睛之间传送药剂。
图1为本发明眼镜片的第一个实例的分解视图。
图2为图1所示镜片的剖视图。
图3为本发明眼镜片的第二个实例的剖视图。
图4为图3所示镜片的边缘部分的细视图。
图5示出了本发明的一个镜片坯组件，用这组件可以制造诸如图3所示的镜片。
图6示出了本发明的镜片坯组件的另一个实例。
图7示出了一个可以用于超声焊接图5和图6所示镜片坯组件的型架和超声焊接机。
图1和图2大体地示出了本发明的第一个实例。眼镜片10。由图可见，镜片10包括一个第一镜片构件12和一个第二镜片构件14。镜片构件12和14都有一个光滑的外表面OS和一个内表面IS。镜片构件12和14的内表面IS一直延展到一个绕镜片周边分布的环形边缘E。镜片构件12和14中至少有一个构件的内表面IS上（图1所示的是在镜片构件12的内表面IS上）制成一个多焦衍射波带板16。如果镜片10是为外科植入用，则还有触觉件18。镜片10的本体（即除了触觉件18以外的那部分）的直径对于植入镜片而言通常在7.0毫米到7.5毫米之间。但根据实际应用的特殊要求也可以超出这个范围。
边缘E起着结合面的作用。如图2所示，镜片构件12和14在其边缘E处固定地结合在一起。可以用粘合剂20粘合这二个构件。在下面要说明的另一个实例中，镜片构件是用超声焊接焊在一起的。换句话说，镜片构件12和14可以用边缘E上的机械镇定，熔焊式热层压处理（未示出）接合。一旦透镜构件12和14已经接合在一起。它们的内表面IS就形成和限定了一个镜腔22。镜腔22贴邻衍射波带板16，腔内可以充有物质24，如图2所示。或者，镜片10做成镜腔22是真空的。
可以将多焦衍射波带板16设计成各种已知的或常规的型式。在图1和2所示的实例中，波带板16是由镜片构件12的内表面IS上的物理结构形成的。或者说，通过将一种杂质掺入部分透镜构件12使得这个掺杂区的折射率变得不同于邻近的透镜构件部分和镜腔22的折射率可以形成衍射波带板16。镜片10的光学放大倍数取决于波带板16的衍射情况和镜片构件12和/或14的折射情况。
可以用许多不同的材料来制造镜片构件12和14。例如可以用比较不透水的材料。如有机玻璃（PMMA），硅丙烯酸盐和全氟聚合物。或者也可用诸如一些硅树酯和水凝胶那样的亲水或含水的材料。专用的水凝胶有丙烯酸盐的均聚物和共聚物，以及在侧链上至少有一个羟基的丙烯酸酯的酯类， 如二羟乙基丙烯酸酯（HEMA）、乙二醇二丙烯酸酯、羟基乙氧基丙烯酸酯和丙三基丙烯酸酯;还有单基物的聚合物和共聚物，如甲氧乙氧基丙烯酸酯、甲氧二乙氧基丙烯酸酯，甲氧基丙烯酸酯，甲基丙烯酸，乙烯醇，乙烯醋酸酯，以及N乙烯基二吡咯烷酮和有关的N链烯基二吡咯烷酮。也可以用交叉链结的水凝胶。
这些材料的折射率通常在1.43至1.5之间，为了使一个所构成的多焦衍射波带板16能够工作，中央腔22中的真空或物质24的折射率必需与邻近的内表面（波带板就形成在这表面上）部分的折射率不同。如果这二个折射率相差较大（例如大于0.1），则波带板16表面结构的实际尺寸就比较小（例如峰一谷尺寸为2毫米）虽然这可以减小做有波带板的透镜构件的总厚度。但要将波带板做到所要求的容差比较困难。如果折射率相差较小，例如在0.04至0.07之间，可以用峰一谷为7毫米的表面结构。这些比较大的表面结构就比较容易被制造得满是所要求的尺寸容差。
镜腔22可以充以固体或液体材料24。对于固体材料24可以用一些使紫外线和光线弯曲的聚合物。例如3M材料酰胺基氨基硅氧烷（Acglamidoamidosiloxane    ACMAS）和甲酰胺基氨基硅氧烷（Methacglamido    Amido    Siloxane    MACMAS），及道氏粒形化合物系列硅酮树脂182和硅橡胶Q-7485A/B（DoW    Corning    com-pounds    Sglgard    182    and    Silastic    Q-7485A/B）。也可以用诸如空气那样的气体或诸如盐溶液那样有益于生理健康液体。具有适当所选特性的盐溶液是一种合乎需要的材料。因为它可以和人眼内的液体相比，并且折射率也相同。
镜片22也能充以用来治疗邻近镜片10的眼睛各部分的药物。为此，镜片10必需要有在镜腔22和眼睛之间传送药物的输液机构。例如，镜腔22可以充以液体抗生素或降低眼压的药物。如图所示那样的穿过镜片构件14的小孔26可以用来控制将流体从镜腔22传送到眼睛的情况。小孔26的大小控制了流体交换的速度。此外，如果镜片构件12和14用亲水材料制成。就也可以将流体从镜腔22内传送出来。在传送流体期间，镜腔22内流体材料24的折射率应该保持不变，以便保证波带板16的光学效果。如果开始时充入镜腔22的流体的折射率与将要代替这些流出镜腔的流体的眼液的折射率接近的话，就可以达到这个目的。
镜片构件12和14能用复制方法（如：注塑成型）直接生产。此外，镜片构件12和14也可以用镜片坯通过机械加工或其它方法制成。虽然在所示的实例中镜片构件12和14都具有凸的外表面OS，但根据要求镜片构件所起到的折射的光学作用情况，其中一个构件或二个构件的外表面可以是凹的或平的。类似，内表面IS也可以是平的或凸的。边缘E可以在将外表面OS加工成所要求的形状前或加工后装合在一起。在镜片构件12和14已经装合在一起以后就可以把液体材料24注入到小腔22内。或者在装合镜片构件12和14的同时将液体或固体材料24充满小腔22。镜片构件12和14也可以是多层构件。制造如10那样的镜片所用的超声波焊接技术在本说明书的下面一些部分还要较为详细地加以说明。
与原有技术的那些相比，如10那样的镜片具有一些值得注意的优点。由于衍射波带板16是在镜片10内而不是在外表面OS上，因此就不会出现通常与在这种结构暴露于人眼的情况下会积累在上面的无机物。蛋白质垢和碎屑有关的问题。也防止了磨损和擦伤角膜。将镜腔22内的药物24传送给眼睛或眼腔是一种十分方便的方法，省得病人必需去医院治疗。因此上述结构有利于外科处理后的愈合，有助于防止与眼睛有关的疾病或其它的并发症。
本发明的另一个实例，眼镜片30，可以参照图3和图4加以说明。与上面所说明的眼镜片10类似，镜片30包括第一和第二镜片构件32和34，它们有内表面IS和外表面OS。镜片构件32的内表面IS包括一个多焦衍射波带板36。镜片构件32和34的环形边缘E结合在一起形成一个紧贴波带板36的镜腔42。镜腔42内可以用注射或其它方法充以一种物质44。除了边缘E和把二个边缘结合在一起的方法有所不同外，眼镜片30的其它构件及特性与上述镜片10的相同。
通过将镜片构件32和34的边缘E放在超声能量下把它们焊接在一起。为了便于焊接加工，一个镜片构件（图3和4中为镜片构件34）的边缘E有一个凸台50和一个斜削的导能环52。在所示的实例中凸台50是环状的。环绕边缘E伸展，凸 台50做成伸入镜片构件32内紧贴其边缘E。起着定位件作用。使这二个镜片构件对准。环状导能环52环绕镜片构件34从它的边缘E上伸出，被放到紧贴镜片构件32的边缘E的位置上。在所示的实例中，导能环52的截面呈三角形。导能环52的侧壁与底所成的角度大致为60°，但可以有所不同（例如在45°至70°之间）。导能环52的高度和宽度也可以有所不同，当宽度在0.005至0.015英寸（0.127至0.381毫米）范围内时业已发现高度在0.005至0.009英寸（0.127至0.229毫米）范围内较为合适。导能环52将超声能量引导至导能环52与镜片构件32接触的点上，这有利于将这二个构件高质量地焊在一起。
在凸台50的外缘51和与之相邻的镜片构件32的表面53之间的间隙起着超声焊接时容纳从导能环52来的被熔化材料的熔料的作用，以防止这材料流入镜腔42。这个间隙应该是够宽。使得凸台50嵌入镜片构件32不会使镜片构件32和34中任何一个构件发生变形，并且使从导能环52来的被熔化材料流入封住这间隙。如果间隙太大，被熔化材料将填不满间隙，而可以显露出这条间隙来。业已证明间隙在0.005至0.007英寸（0.127至0.178毫米）范围内情况良好。
如图4所示，有一个或几个横向方孔54（图中只示出一个）贯穿导能环52。方孔54起着镜片10上小孔26同样的作用，它有利于在镜腔42和眼睛和眼腔（未示出）之间传送液体物质44。方孔54还起着排气孔的作用。当在焊接期间置入镜腔42的粘性物质（如ACMAS）充至镜腔边缘时排出空气。眼镜片30具有上述眼镜片10的所有优点。此外，由于采用超声焊接，有效地防止了镜片构件32和34的光学畸变。
图5大体示出了本发明的一个镜片坯组件60。组件60包括未完工的镜片构件62和64。在所示的这个实例中，镜片构件62的内表面IS总体来说是凹的。镜片构件64的内表面IS是平的，在伸入到镜片构件62内的圆台70上形成。多焦衍射波带板66做在镜片构件62的内表面IS上。镜片构件64的接合缘E上有一个导能环或者叫斜削脊72，它与镜片构件62相接。脊72可以与以上参照图3和图4所说明的镜片30的导能环52完全相同。一旦在镜片构件62和64的边缘将这二个构件结合在一起，就可以用研磨或其它常用的机械加工的方法按患者的规格将外表面OS加工好。如图1中的18所示的触觉件也可以从镜片构件62和64加工出来，镜片坯组件60内的镜腔74可以充以一种物质（未示出），其情况与参照镜片10和30所作的说明相同。镜片构件62和64也可以用粘合剂或诸如就镜片10所作说明那样的其它焊接技术互相接合在一起。除了具有镜片10和30的优点以外，如60那样的镜片坯组件可以存放在仓库内，需要时加工成所需规格。
图6示出了另一个镜片坯组件60′。镜片坯组件60′做成可以用超声焊接技术装配的形状。除了导能环71外。镜片坯组件60′的其它各组成部分与以上就图5说明的镜片坯组件60的相应组成部分完全相同。以带撇（即）的相应数字表记。环形的导能环71绕镜片坯构件64′的边缘E伸出，具有一个展宽了的平滑顶面，该顶面与镜片坯构件62′的边缘E相接。在所示的这个实例中，导能环71的横截面是矩形，因此导能环71具有一个平的顶面。导能环71的高度所以在0.127至0.229毫米之间变动，而宽度则在0.127至0.381毫米之间变动。诸如用水凝胶材料制造并且有一个导能环71的构件62′和64′那样的眼镜片构件可以用下面所说的超声接合技术可靠地焊在一起。
用图7所示的超声焊接机80和型架82能可靠和有效地将镜片12和30以及镜片坯组件60和60′的单个镜片构件接合在一起。仅为说明起见，图7中示出镜片坯组件60′的情况。型架82包括一个由一个或几个壁86围成的井84。井84的尺寸保证可以稳固地安置镜片坯组件60′，但在镜片坯组件60′放入或取出时不会发生多大形变。在用下述工序焊接镜片构件时应该将各镜片构件（如62、64和62′、64′）擦净，不带脏屑。
在一个实例中，超声焊接机80是一台布朗松（Branson）4AE型焊接机。焊接机80有一个供能器88，通过气缸92，供能器88安装在基座90上，可以相对基座90运动。供能器88所产生的超声能量由喇叭94耦合给镜片组件60′。通过喇叭94加到镜片组件60′的压力由气缸92控制。气缸92必需能施出足够的压力以便将镜片构件62′和64′高质量地接合在一起。但是压力过高会引起过焊，反而接合不好。将气缸92调到1.00至1.25 英寸（25.4至31.75毫米）所得到的压力已经证明可以得到良好的结果。最好用一种产生频率为40千赫的超声能量的供能器88来焊接诸如包括用PMMA和水凝胶制成的那些构件62′和64′那样的镜片构件。已经证明喇叭94的直径如果等于或大于正要焊接的镜片构件上导能环（例如镜片构件64′的导能环71）的直径的话焊接强度最高，质量最好。
下面就来说明所推荐的一种用超声焊接机80和型架82超声焊接具有厚度为2.5毫米带充空氧的镜腔74那样的PMMA镜片构件62和64的方法。这二种PMMA镜片构件62和64的导能环72最好横截面是三角形的，高度为0.005英寸（0.127毫米）。在温度100-120°F（37.8-48.9℃）预热四十五分钟后放入井84内以后，喇叭94就以压强为50-75磅/英寸2（344.9-517.1千牛顿/米2）压在镜片构件64上，在一个优选实例中所用的压强为60磅/英寸2（413.7千牛顿/米2）。然后，激励供能器88焊接一段时间，在这段时间内在供能器邻接喇叭94的那一端所测到的能量其峰值达到140-150焦耳。已经证明焊接时间在0.18至0.30秒的范围内效果良好，而为0.20秒时最佳。焊接以后，超声焊接机80继续压在镜片组件60上，保持一段时间，大致为0.25至0.40秒，最好是0.3秒。已经证明采用这些工序可以在PMMA镜片构件62和64之间形成高质量的焊缝。这个焊缝要在50倍的显微镜下才能勉强看得出来，至少需用10磅的力或44.5牛顿（如用一个英斯屈隆流变仪Instron rheometer测出）才能使这焊缝破裂。
当要将PMMA镜片构件62和64焊接起来做成一个具有充满盐溶液的镜腔74的镜片组件60时，采用脱气盐溶液来减少否则会截留在镜腔内的空气或其它气体量是有利的。在一个具有充满盐溶液的镜腔74那样的PMMA镜片组件60的优选实例中，导能环72的高度为0.008英寸（0.203毫米）。开始，在井84内部分充以脱气盐溶液。然后将一个下镜片构件（如62）放入井84内。来回动一下，使各种气体冒到溶液表面逸出。在再加入一些盐溶液到井84里以后，把上镜片构件（如64）放在下镜片构件62上面，使得气体不会被截留在镜腔74内。然后，来回移动一下上镜片构件64，排出所有空气或其它残存的气体。
用来与带有一个充满盐溶液的镜腔74的镜片构件60接合的镜片构件64最好有一个高度为0.008英寸（0.203毫米）的导能环。为了能获得置佳焊接。镜片构件62和64应该在温度为90至100°F（32.2-37.8℃）上预热一小时，在焊接期间施以100磅/英寸2（689.5千牛顿/米2）的力。已经发现，如果力为90-115磅/英寸2（620.6-792.9千牛顿/米2）效果也很好。焊接时间为0.25-0.35秒的效果很好而为0.30秒最佳。焊接期间在供能器88所监测到的峰值能量应该达到180-220焦耳。焊接后，应该将镜片组件60在压力下保持一段时间，在0.30-0.40秒的范围内，最好是0.35秒。已经证明具有一个充满盐溶液的镜腔74，按上述条件制造的那样PMMA镜片组件60在其镜片构件62和64之间具有一个高质量的焊接区。
一种用来超声焊接PMMA镜片构件62和64以便形成一个具有充以诸如ACMAS和MACMAS之类填充材料的镜腔74的镜片组件60的优选方法是将镜片构件在100-120°F（37.7-48.9℃）的温度下预热45分钟后再放入井84内。ACMAS和MACMAS材料比较粘稠。在使用前应该加以脱气。在镜片构件62已经放入井84内以后，可以用一个注射器将是量的填充材料放在该镜片构件的内表面IS上。然后将镜片构件64复在镜片构件62上，使填充材料填满整个镜腔74。要求在镜片构件62的内表面IS上只放置填满镜腔74所必需的那么多的填充材料。高度为0.007-0.009英寸（0.178-0.229毫米）的导能环将有助于获得一个高质量的焊接区，即使放在镜片构件上的填充材料太多而溢出导能环也没有关系。在上述工序以后，在压强为65-75磅/英寸2（448.2-517.1千牛顿/米2），焊接时间为0.20-0.27秒，峰值能量为100-115焦耳和保持时间为0.25-0.40秒的条件下在镜片构件62和64之间可以形成一个高质量的焊接区。最佳焊接条件是压强为70磅/英寸2（482.6千牛顿/米2）。焊接时间为0.23秒，峰值能量为110焦耳和保持时间为0.30秒。
人的是业已证明诸如平衡温度大于25.0%那样的水凝胶镜片构件62′和64′可以用图7所示形式的焊接机80和型架82进行焊接。
已经用这种设备对由平衡湿度为38.5%的 HEMA水凝胶（可从Bausch    Lomb和Hgdron购得）制成的镜片构件62′和64′进行了焊接。或许更惊人的是诸如具有平衡湿度大于55%那样的水凝胶镜片构件62′和64′能用焊接机80和型架82焊接。例如，用在泰亨（Tahan）的英国专利出版物2，171，106中所披露的平衡湿度为61.0%的水凝胶材料制造的镜片构件62′和64′已经用这设备可靠地焊接在一起了。
所推荐的一个途径是使用厚度为2.0毫米的水凝胶镜片构件62′和64′，其中一个构件上有一个横截面大体呈矩形的导能环71。导能环71的高度可以为0.005-0.007英寸（0.127-0.178毫米），宽度为0.005-0.015英寸（0.127-0.381毫米）。在室温（如：65-80°F即18.3-26.7℃）下将水凝胶镜片构件62′和64′放入井84内。调整气缸92使它通过供能器88和喇叭94在镜片构件64上加以压强为8至10磅/英寸2（55.1至68.9千牛顿/米2）的压力。在焊接时间为0.15-0.22秒，峰值能量为10-25焦耳，保持时间为0.15-0.25秒的情况下在镜片构件62和64′之间能够获得高质量的焊接。最佳焊接条件是焊接时间为0.17秒而保持时间为0.20秒。
虽然已经就优选实例对本发明作了说明，但精于该技术的将会公认在本发明的精神和范围内可以在形状和细节上进行各种改变。举例来说，按照本发明所提出的眼镜片可以具体做成接触式镜片，眼内镜片，人工角膜和板内植入片。
