相关专利申请
本专利申请要求2012年2月22日提交的美国专利申请序列号13/401,952、2011年2月28日提交的美国临时申请序列号61/447,469、以及2011年3月18日提交的美国临时申请序列号61/454,205的优先权,每一专利申请的内容均以引用方式并入本文。
使用领域
本发明描述了一种用于眼科装置的功能化插入物,该功能化插入物由多个堆叠功能层形成,而且在一些实施例中,本发明描述了具有由多个堆叠层形成的功能化插入物的眼科镜片的制造方法和设备。
背景技术
传统上,眼科装置例如接触镜片、眼内镜片或泪点塞包括具有矫正、美容或治疗性质的生物相容性装置。例如接触镜片可提供以下功能中的一种或多种:视力矫正功能、美容增强作用以及治疗作用。每种功能由镜片的物理特性提供。将折射性质结合到镜片中的设计可提供视力矫正功能。结合到镜片中的颜料可提供美容增强作用。结合到镜片中的活性剂可提供治疗功能性。无需使镜片处于通电状态即可实现这些物理特性。泪点塞传统上为无源装置。
最近,有理论表明有源元件可被结合到接触镜片中。一些元件可包括半导体器件。一些例子示出了在置于动物眼睛上的接触镜片中嵌入半导体器件。还描述了如何在镜片结构自身内以多种方式使有源元件被通电和激活。由镜片结构限定的空间的形貌和大小为各种功能的限定产生新的且具有挑战性的环境。通常,此类公开已包括分立装置。然而,可获得的分立装置的尺寸和功率需求不一定有助于包含在人眼上佩戴的装置中。
发明内容
因此,本发明包括可制成能够通电并被结合到眼科装置中的插入物的组件的设计。插入物可由多个层形成,每个层可具有独特的功能性;或具有混合的但是处于多个层中的功能性。在一些实施例中,这些层可具有专门用于产品通电或产品激活的层,或可具有用于控制镜片主体内各功能组件的层。此外,本发明提出用于形成具有由堆叠功能化层所形成的插入物的眼科镜片的方法和设备。
在一些实施例中,所述插入物可包含处于通电状态的层,其能够为能传导电流的组件供电。这些组件可包括例如下列中的一种或多种:可变光学镜片元件和半导体器件,其可位于堆叠层插入物中或换句话讲连接到该插入物。一些实施例还可包括浇铸模塑的有机硅水凝胶接触镜片,其中堆叠功能化层的刚性插入物或可成形的插入物以生物相容的方式被包含在眼科镜片中。
因此,本发明包括以下公开内容:一种具有堆叠功能化层部分的眼科镜片、用于形成具有堆叠功能化层部分的眼科镜片的设备及其方法。如本文所讨论,可由多个层以各种方式形成插入物,且所述插入物可被布置成邻近第一模具部件和第二模具部件中的一者或两者。反应性单体混合物被放置在第一模具部件和第二模具部件之间。第一模具部件被布置为邻近第二模具部件,从而形成镜片腔体,其中通电介质基底和至少一些反应性单体混合物置于所述镜片腔体中;所述反应性单体混合物被暴露于光化辐射以形成眼科镜片。通过控制反应性单体混合物所暴露的光化辐射可形成镜片。

通常,根据前述这些实施例,介质基底111通过自动化装置嵌入眼科镜片中,该自动化装置将能量源放置在与用来制作镜片的模具部件相关的所需位置。
模具
现在参见图1,图中示出了用于眼科镜片的示例性模具100,其具有介质基底111。如本文所用,术语模具包括具有腔体105的构造100,可将镜片形成混合物110分配到腔体105中,使得当镜片形成混合物反应或固化后产生期望的形状的眼科镜片。本发明的模具和模具部件100由不止一个“模具部件”或“模具件”101-102构成。可将模具部件101-102组合在一起,这样在模具部件101-102之间形成腔体105,镜片可在此腔体内形成。优选地,模具部件101-102的这种组合是暂时的。镜片形成后,可以再次分离模具部件101-102以取下镜片。
至少一个模具部件101-102的表面103-104的至少一部分与镜片形成混合物接触,使得镜片形成混合物110反应或固化后,表面103-104向与其接触的镜片的部分提供期望的形状和形式。对于至少一个其它模具部件101-102也是如此。
因此,例如,在一个优选实施例中,模具组件100由两个部件101-102形成,即凹形件(前件)102和凸形件(后件)101,二者之间形成腔体。凹形表面104与镜片形成混合物接触的部分具有将在模具组件100中生产的眼科镜片的前曲面的曲率,而且该部分足够光滑,并被形成为使得通过与凹形表面104接触的镜片形成混合物的聚合而形成的眼科镜片的表面为光学上合格的。
在一些实施例中,前模具件102还可以具有围绕圆形周围边缘108并与其成一整体的环状凸缘,前模具件102在垂直于轴并从凸缘延伸的平面内从凸缘延伸(未示出)。
镜片形成表面可以包括具有光学质量表面光洁度的表面103-104,这表示它足够光滑并被成型为使得通过与模具表面接触的镜片形成材料的聚合而形成的镜片表面为光学上合格的。此外,在一些实施例中,镜片形成表面103-104可具有几何形状,该几何形状对赋予镜片表面所期望的光学特性而言是必需的,所期望的光学特性包括但不限于球面、非球面以及柱面度数、波前像差矫正、角膜形貌特征校正等,以及它们的任何组合。
能源109可设置在示出为111的介质基底上。介质基底111可为其上可设置能量源109的任何接纳材料,在一些实施例中还可包括电路路径、组件以及用于使用能量源的其他方面。在一些实施例中,介质基底111可以是在镜片形成时被掺入到镜片中的材料的透明涂层。透明涂层可包含例如如下所述的颜料、单体或其它生物相容性材料。另外的实施例可包括包含插入物的介质,而插入物可为刚性的或可成形的。在一些实施例中,刚性插入物可包括提供光学性质例如用于视力矫正的那些性质的光学区和非光学区部分。可将能量源设置在该插入物的光学区和非光学区中的一者或二者上。再有一些实施例可包括可为刚性或可成形的环状插入物、或围绕使用者透过看到的光学区的某一形状。
各种实施例还包括将能量源109设置在介质基底111上,然后将介质基底111设置在用于形成镜片的模具部分内。介质基底111还可包括一个或多个能通过能量源109接受电荷的组件。
在一些实施例中,具有介质基底111的镜片可包括硬心软边设计(rigidcenter soft skirt design),其中中央的刚性光学元件分别在前表面和后表面上与大气和角膜表面直接接触,并且其中镜片材料(通常为水凝胶材料)的软裙边附接到刚性光学元件的周边,刚性光学元件还用作为所得眼科镜片提供能量和功能的介质基底。
另一些实施例包括介质基底111,该介质基底为完全封装在水凝胶基质内的刚性镜片插入物。作为刚性镜片插入物的介质基底111可例如采用显微注射成型技术制造。实施例可包括例如聚(4-甲基-1-戊烯)共聚物树脂,其直径介于约6mm至10mm之间,前表面半径介于约6mm和10mm之间,后表面半径介于约6mm和10mm之间,中心厚度介于约0.050mm和0.5mm之间。一些示例性实施例包括此类插入物,其直径为约8.9mm,前表面半径为约7.9mm,后表面半径为约7.8mm,中心厚度为约0.100mm,边缘轮廓为约0.050半径范围。一个示例性微成型机器可包括Battenfield有限公司提供的Microsystem50五吨系统。
介质基底可设置在用于形成眼科镜片的模具部件101-102内。
模具部件101-102材料可包括例如以下一种或多种聚烯烃:聚丙烯、聚苯乙烯、聚乙烯、聚甲基丙烯酸甲酯和改性聚烯烃。其它模具可包括陶瓷或金属材料。

可与一种或多种添加剂组合以形成眼科镜片模具的其它模具材料包括例如Zieglar-Natta聚丙烯树脂(有时称为znPP)。一种示例性Zieglar-Natta聚丙烯树脂以商品名PP9544MED出售。PP9544MED为用于按照FDA法规21CFR(c)3.2进行清洁成型(clean molding)的澄清无规共聚物,由ExxonMobile Chemical Company提供。PP9544MED为具有乙烯基的无规共聚物(znPP)(以下称9544MED)。其他示例性的Zieglar-Natta聚丙烯树脂包括:Atofina聚丙烯3761(Atofina Polypropylene3761)和Atofina聚丙烯3620WZ(Atofina Polypropylene3620WZ)。
另外,在一些实施例中,本发明的模具还可以包含诸如聚丙烯、聚乙烯、聚苯乙烯、聚甲基丙烯酸甲酯、主链上含脂环部分的改性聚烯烃以及环状聚烯烃的聚合物。这种共混物可用于任何一半或两半模具上,其中优选的是将这种共混物用于后曲面,而前曲面包含脂环族共聚物。
在根据本发明制备模具100的一些优选的方法中,按照已知的技术进行注模,然而,实施例也可以包括用其他技术成型的模具,所述其他技术包括例如车床加工、金刚石车削或激光切割。
堆叠功能化层插入物
现在参见图2,其示出了被形成为堆叠功能化层插入物的介质基底111的一个实施例的示例性设计。本发明涉及制备和形成如下介质基底的新型方法,所述介质基底可以符合前述技术的方式来用于并形成于眼科镜片中。为清晰地进行说明,示出并描述了示例性介质基底210,其包括具有光学镜片区域211的全环形环,而此并非用于限制本发明的范围。对于本领域的技术人员而言可显而易见的是,本说明书中所述的发明技术类似地适用于各种形状和实施例,该各种形状和实施例针对各种介质基底进行一般描述。
现在参见图3,其示出了使用堆叠层介质基底的完全成形的眼科镜片的一些实施例的三维表示,其中项210被展示为项300。该表示示出了眼科镜片的局部切开部分,以了解在装置内存在的不同的层。项320显示介质基底的包封层的主体材料的横截面。该项围绕眼科镜片的整个周边,可被设想用于项210中的类型的插入物。对本领域技术人员清楚的是,实际的插入物可包括仍然能够处于典型眼科镜片的尺寸限制内的全环形环或其他形状。
项330,331和332旨在示出可存在于形成为功能层堆叠的介质基底中的多个层中的三个层。在一些实施例中,单个层可包括下列中的一种或多种:具有有助于特定目的的结构、电特性或物理特性的有源和无源组件和部分。
在一些实施例中,层330可包括电源,例如下列中的一种或多种:层330内的电池、电容器和接收器。于是,在非限制性的示例性意义上,项331可包括层中的微电路,该微电路检测眼科镜片的致动信号。在一些实施例中,可包括功率调节层332,其能够接收来自外部源的功率以对电池层330充电,并且在镜片未处于充电环境中时控制来自层330的电池功率的使用。功率调节源也可控制发往示例性有源镜片的信号,该有源镜片在介质基底的中心环形切口中被显示为项310,而在图2中被标识为211。
图4示出了堆叠功能层插入物400的一些实施例的较近剖视图。在一些实施例中,眼科镜片410的主体中嵌入有功能化层插入物420,该功能化层插入物围绕并连接至有源镜片组件450。对于本领域的技术人员可能清楚的是,此例子显示可被放置于眼科镜片中的嵌入式功能的多种实施例中的仅一个实施例。
在插入物的堆叠层部分中展示有多个层。在一些实施例中,所述层可包括多个基于半导体的层。例如,项440,即堆叠中的底层,可为薄硅层,该硅层上限定有用于各种功能的电路。可在堆叠中找到另一薄硅层作为项441。在非限制性实例中,此种层可随装置的通电情况变化。在一些实施例中,这些硅层可通过显示为项450的中间绝缘层而彼此电绝缘。项440,450和441的表面层的彼此交叠的部分可通过使用粘合剂薄膜而彼此粘合。对于本领域的技术人员显而易见的是,多种粘合剂可具有用于将薄硅层粘附至绝缘体例如环氧树脂并使其钝化所需的特性。
多个堆叠层可包括附加层442,在非限制性实例中,该附加层可包括具有能够激活并控制有源镜片组件的电路的薄硅层。如上所述,当堆叠层需要彼此电绝缘时,可将堆叠绝缘层包括在电活性层之间,且在此例子中,项451可表示此种绝缘层,包括堆叠层插入物的一部分。在本文所述的一些例子中,已提及由薄硅层形成的层。一般技术的使用范围可扩展至不同实施例,其中薄的堆叠层的材料定义以非限制性方式包括其他半导体、金属或复合层。薄层的功能可包括电路,但也可包括其他功能,举几个例子来说,如信号接收、能量处理和储存以及能量接收。在一些包括不同材料类型的实施例中,可能需要选择与堆叠层相互作用的不同粘合剂、包封材料和其他材料。在示例性实施例中,环氧树脂的薄层可将显示为440,441和442的三个硅层与两个氧化硅层450和451粘合。
如在一些例子中所述,薄的堆叠层可包括形成于硅层中的电路。可存在多种制造此种层的方式,然而本技术的半导体处理设备的标准和状态可利用一般处理步骤在硅片上形成电子电路。在电路形成于硅片上的适当位置中之后,可利用晶圆处理设备来将晶圆从几百微米打薄为50微米或以下的厚度。在打薄之后,可从晶片将硅电路切割或“切片”成适合眼科镜片或其他应用的适当形状。在下文中,本文所公开的堆叠层发明的不同示例性形状显示于图6中。将在下文中对此进行详细阐述,然而,“切片”操作可使用各种技术选项来切出具有弯曲、圆形、环形、直线和其他更复杂形状的薄层。
在一些实施例中,当堆叠层执行与电流相关的功能时,可能需要在各堆叠层之间提供电接触。在半导体封装的一般技术领域中,各堆叠层之间的此种电连接具有包括以下的一般解决方法:打线接合、焊料隆起、硅通孔和线材沉积方法。线材沉积的一些实施例可使用其中在两个连接焊盘之间印刷导电墨水的印刷方法。在其他实施例中,线材可由能量源(例如激光)以物理方式限定,该线材与能够在能量源照射处产生电连接的气体、液体或固体化学媒介进行相互作用。在通过各种方式沉积金属膜之前或之后,可从光刻处理获得又一些互连定义实施例。
在本发明中,如果所述层中的一个或多个层需要将电信号传达到其外部,则所述一个或多个层可具有不被钝化和绝缘层覆盖的金属接触焊盘。在许多实施例中,这些焊盘将位于所述层的周边上,其中后续堆叠层不会覆盖该区域。在此种类型的实施例的例子中,在图4中,互连线材430和431被展示为层440,441和442的电连接周边区域。对于本领域的技术人员可显而易见的是,可存在多种用于定位电连接焊盘的布局或设计以及将各种焊盘电连接在一起的方式。此外,可能显而易见的是,根据哪些电性链接焊盘被连接且这些焊盘连接至哪些其他焊盘的选择可得出不同的电路设计。另外,焊盘之间的线材互连的功能在不同的实施例中可不同,举几个例子来讲,包括以下功能:电信号连接、从外部源接收电信号、电力连接、以及机械稳定。
在先前的论述中,提出了非半导体层可包括本发明技术中的堆叠层中的一个或多个层。可能显而易见的是,可存在源自非半导体层的各种各样的应用。在一些实施例中,所述层可限定通电源,如电池。在一些情形中,此种类型的层可具有用作支撑化学层的支撑基片的半导体,或在其他实施例中可具有金属或绝缘基片。其他层可源自本质上主要为金属的层。这些层可限定天线、导热路径、或其他功能。可存在半导体层与非半导体层的多种组合,所述组合包括处于本发明技术的实质范围内的适合应用。
在其中各堆叠层之间具有电连接的一些实施例中,在限定连接之后需要对所述电连接进行密封。存在可符合本文技术的多种方法。例如,可将用于将各种堆叠层保持在一起的环氧树脂或其他粘合材料重复涂覆在具有电性互连的区域。另外,在一些实施例中,钝化膜可沉积在整个装置上,以包封用于互连的区域。对于本领域的技术人员而言可能显而易见的是,在项技术中可使用多种包封和密封方案来保护、增强和密封堆叠层装置以及其互连和互连区域。
组装堆叠功能化层插入物
继续参见图5,其展示了用于组装堆叠功能化层插入物的示例性装置的近距离视图(项500)。在该例子中,显示其中堆叠层在所述层的任一侧上均不对齐的堆叠技术。项440,441和442同样可为硅层。在图的右侧,可见项440,441和442的右侧边缘彼此不对齐,其在替代实施例中可能如此。此种堆叠方法可允许插入物采用与眼科镜片的总体轮廓相似的三维形状。同样在一些实施例中,此种堆叠技术可允许各层由尽可能最大的表面积制成。在功能用于能量储存和电路的层中,此种表面积最大化可为重要的。
一般来讲,前述堆叠插入物的许多特征可在图5中观察到,图5包括堆叠功能层440,441和442;堆叠绝缘层450和451;以及互连件430和431,所述互连件可包括硅通孔。另外,可观察到用于在组装时支撑堆叠功能化层插入物的支撑夹具(项510)。可显而易见的是,项510的表面轮廓可呈现大量形状,所述形状会改变所述表面上的插入物的三维形状。
一般来讲,夹具510可设置有预定的形状。夹具510可涂覆有不同的层(项520)以用于许多目的。在一些实施例中,以非限制性方式,所述涂层可首先包括聚合物层,所述聚合物层使得能够容易地将插入物结合到眼科镜片的基材中,且所述涂层甚至可由有机硅聚合物材料形成。接着,可在有机硅聚合物涂层上沉积环氧树脂涂层,以将底部薄的功能层440粘合至涂层520。可用相似的环氧树脂涂层来涂覆下一绝缘层450的底面,随后将该绝缘层置于其在夹具上的适当位置处。清楚的是,在一些实施例中,所述夹具可具有在组装装置时使各堆叠层的正确布置相互对齐的功能。接着,可以重复的方式组装插入物的其余部分、限定互连件、并随后包封插入物。在一些实施例中,随后用有机硅聚合物涂层来从上向下涂覆被包封的插入物。在针对项520使用有机硅聚合物涂层的一些实施例中,可通过所述有机硅聚合物涂层的水合作用而使组装的插入物与夹具510分离。
夹具510可由多种材料形成。在一些实施例中,所述夹具可由在制造标准接触镜片时用于制造成型件的相似材料形成和制成。此种使用可支持灵活地形成用于不同插入物形状和设计的各种夹具类型。在其他实施例中,所述夹具可由如下材料形成:所述材料自身不会或在具有特殊的涂层时不会粘附至用于将不同的层彼此粘合的化学混合物。可显而易见的是,此种夹具的构型可存在多种选择。
显示为项510的夹具的另一方面是其形状以物理方式支撑位于其上的层。在一些实施例中,各层之间的互连可由打线接合的连接件形成。在打线接合的过程中,对线材施加明显的力以确保其形成良好的结合。在此种结合过程中,各层的结构支撑可为重要的,并可由支撑夹具510来执行。
显示为项510的夹具的又一功能是该夹具上具有对齐结构,所述对齐结构能够使功能化层的各组件不仅相对于彼此线性地对齐,而且沿表面径向地对齐。在一些实施例中,所述夹具可使各功能层的方位角围绕中心点相对于彼此对齐。无论所制造的插入物的最终形状为何,可显而易见的是,组件夹具可适用于确保插入物的各组件为实现其功能和正确的互连而适当地对齐。
继续参见图6,可得出对堆叠层插入物的形状的更一般性讨论。在根据本技术的一般形状的子集中,显示了某些样本性的形状变化。例如,项610显示由基本上圆形层件形成的堆叠插入物的俯视图。在一些实施例中,以交叉影线显示的区域611可为其中移除层材料的环形区域。然而,在其他实施例中,显而易见的是,用于形成插入物的堆叠层的组件可为不具有环形区域的圆盘。尽管此种非环形插入物形状在眼科应用中的实用性可能受限,然而本文发明技术的实质并非旨在受内部环形物的存在的限制。
在一些实施例中,项620可展示堆叠功能层插入物的不同实施例。如项621中所示,在一些实施例中,层件可能不仅在堆叠方向上不连续,而且围绕垂直于堆叠方向的方位角方向也不连续。在一些实施例中,可使用半圆形组件来形成插入物。可显而易见的是,在具有环形区域的形状中,局部形状可适用于在层材料形成为具有其功能之后将材料减少需被“切片”或切除的量。
进一步来讲,项630展示了可限定的非辐射状、非椭圆形、以及非圆形插入物形状。如项630中所示,可形成直线形状,或者如项640中所述形成其他多边形形状。在三维透视锥体中,用于形成插入物的各个层件的不同形状可产生圆锥体或其他几何形状。在更一般性的意义上,对于本领域的技术人员显而易见的是,可将各种各样大量形状成形为形状和产品,以讨论可制造有功能性、通电性、活化性等的形状的更一般性的情况。
