本发明提供可用于接触眼镜生产的模型和模型插入物。具体地说,本发明提供可用于制造硅酮水凝胶接触眼镜的高光学质量模型和插入物。
Description
技术领域
本发明涉及可用于接触眼镜生产的模型和模型插入物。具体地说,本发明提供硅酮水凝胶接触眼镜制造用的高光学质量模型和模型插入物。
背景技术
为了美容的原因和视力校正而使用软接触眼镜是众所周知的。典型地说,这些眼镜是用浇铸法制造的。这些眼镜浇铸中使用的半模(mold halves)的生产是先切削金属插入物然后使用该插入物生产该半模的。该插入物的切削工艺可能引起周期性缺陷或周期性结构,而这些可能转移到该半模上。这些半模的模塑表面是足以产生在该半模中浇铸的惯常水凝胶眼镜用的光学质量眼镜的。
然而,在硅酮水凝胶眼镜的浇铸模塑中,该硅酮水凝胶材料准确地复制了该模型表面。因此,该模型表面上的周期性结构会转录到该眼镜表面上。如果这些眼镜涂布一种可溶胀或亲水性涂料,则该涂层的溶胀会放大这些表面缺陷。这些放大的缺陷可能通过产生相干散射(棱镜效应)或眼睛护理医师可见的工具痕迹而损害眼镜佩戴者的视力。因此,该模型可能产生有光学质量不足的表面的涂布硅酮水凝胶眼镜。因此,目前需要能克服这个问题的方法和材料。
发明内容
本发明提供可用于浇铸模塑硅酮水凝胶接触眼镜的模型、该模型生产用插入物、和用本发明模型制作的眼镜。本发明的模型有这样的模塑表面,其上因形成该模型的插入物的切削而产生的周期性结构的幅度和周期性,小于那些会导致在眼镜表面上产生当该眼镜涂布时会影响佩戴者的视觉的光学缺陷的结构幅度和周期性。
在一种实施方案中,本发明提供一种包含、基本组成为、且组成为至少一个光学临界表面的眼镜插入物,其中,该光学临界表面上的周期性结构有小于约3μm的周期性和小于约4nm RMS的幅度。在另一种实施方案中,本发明提供一种用于模塑一种接触眼镜的半模(moldhalf),该半模包含、基本组成为、且组成为至少一个模塑表面,其中,该模塑表面上的周期性结构有小于约3μm的周期性和小于约4nmRMS的幅度。在又另一种实施方案中,本发明提供一种包含、基本组成为、且组成为至少一个表面的硅酮水凝胶接触眼镜,其中,该表面上的周期性结构有小于约3μm的周期性和小于约4nm RMS的幅度。为了本发明之目的,幅度测定是用原子力显微镜法在50×50μm面积上进行的。
所谓“光学临界表面”系指周来产生一个眼镜模型或半模的模塑表面的模型插入物的表面。所谓“模塑表面”系指用来形成一种眼镜的一个表面的模型或半模的表面。
本发明的插入物的光学临界表面较好进行抛光,以使该表面结构无规化和使糙度降低到所希望的水平。该插入物是先用任何一种方便方法,包括但不限于用一种适用材料的单一金刚石尖点车削,来生产的。典型地,该插入物是用一种受控波纹金刚石切削工具成形的,而且用同一种工具进行多达两次精加工。业内一般人士会认识到,受控波纹工具是一种无论在该工具的切削部分的哪一点上进行切削,该点上的半径都是在公差范围内该工具制造者所规定的半径,且只有最低限度局部偏差的工具。这样一种工具使得最终部件切削将是极端精确的。该工具鼻部半径可以在约100~250μm范围内。
该插入物旨在提供本发明的光学临界表面的抛光可以用任何方便的方法进行。较好,抛光是通过使用一种重碳金刚石抛光复合物作用于一种为匹配该插入物半径而成形的布和夹具来进行的。该插入物和夹具放进该抛光机中一段适当时间例如约1分钟,然后取出,用一种适用溶剂例如乙醇擦拭以除去抛光复合物。然后检查该插入物,必要时重复该过程。该插入物最终用任何方便的方法包括但不限于用干涉仪检查,以确保该半径符合设计规格以及该周期性结构有所希望的周期性和幅度。
作为抛光的一种替代,选择使用适合于产生本发明的光学临界表面的条件的车削,使得该周期性结构的幅度和周期性在所希望的区间内。例如,使用以mm/min量度的线性进料速率或该金刚石工具横跨该零件表面车削的速率与以转/min表示的轴速度之比要足以提供每道车线或螺旋之间的所希望增量。为了得到1μm间隔的车线,人们使用5mm/min线性进料和5,000rpm、10mm/min线性进料和10,000rpm、或者能提供1/1000比值的任何数字。为了得到小于300nm间隔的车线,要使用的适当比值是3/10000或者线性进料速率为2.4mm/min而轴速度为8000rpm。
本发明的插入物可以用能以光学抛光制作的任何材料包括但不限于金属、石英、陶瓷、聚合物等构造。适用的金属包括但不限于纯钢、黄铜、铜、镀镍基材、铬、钴-镍、合金马丁钢、AMPCOLOYTM基材等及其组合。较好,该插入物是镀镍铜或镀镍黄铜。可用聚合物材料的实例包括但不限于聚碳酸酯、环状烯烃、尼龙、DELRIN、TEFLON、聚苯乙烯、聚丙烯、聚丙烯腈等及其组合。
这些插入物用来以任何已知方法形成本发明的模型或半模。一般来说,该模型是从该插入物浇铸而成的。典型地,一个适合于形成该模型或半模的模塑表面的插入物将与一个要用来形成该模型或半模的非模塑表面的互补插入物配对。本发明的模型可以从任何适合用于接触眼镜生产的材料制造。适用模型材料包括但不限于聚烯烃例如聚丙烯、聚苯乙烯、和环状聚烯烃、聚丙烯腈材料等及其组合。
本发明的模型和插入物可以用来生产任何类型的硅酮水凝胶眼镜。本发明的眼镜是硅酮水凝胶眼镜,较好是涂布了一种可溶胀涂料的硅酮水凝胶眼镜。适用的硅酮水凝胶材料包括但不限于从硅酮大分子单体,例如美国专利No.4,259,467、4,260,725和4,261,875中所述用侧链亲水基团甲基丙烯酸化的聚二甲基硅氧烷,或者美国专利No.4,136,250;4,153,641;4,189,546;4,182,822;4,343,927;4,254,248;4,355,147;4,276,402;4,327,203;4,341,889;4,486,577;4,605,712;4,543,398;4,661,575;4,703,097;4,837,289;4,954,586;4,954,587;5,346,946;5,358,995;5,387,632;5,451,617;5,486,579;5,962,548;5,981,615;5,981,675;和6,039,913中所述有可聚合官能团的聚二甲基硅氧烷大分子单体制作的硅酮水凝胶。它们也可以用掺入了亲水单体的聚硅氧烷大分子单体例如美国专利No.5,010,141;5,057,578;5,314,960;5,371,147和5,336,797;中所述的那些,或者包含聚二甲基硅氧烷嵌段和聚醚嵌段的大分子单体例如美国专利No.4,871,785和5,034,461中所述的那些制作。所引用专利全部以其全文列为本文参考文献。
适用的材料也可以从oxyperm和ionoperm成分的组合制作,例如美国专利No.5,760,100;5,776,999;5,789,461;5,807,944;5,965,631和5,958,440中所述的那些。这样的共聚物中可以掺入亲水单体,包括甲基丙烯酸2-羟基乙酯(“HEMA”)、丙烯酸2-羟基乙酯、N,N-二甲基丙烯酰胺(“DMA”)、N-乙烯基吡咯烷酮、2-乙烯基-4,4-二甲基-2-噁唑啉-5-酮、甲基丙烯酸、2-羟基乙基甲基丙烯酰胺。可以掺入另外的硅氧烷单体,例如甲基丙烯酸三(三甲基甲硅烷氧基)甲硅烷基丙酯,或美国专利No.5,998,498;3,808,178;4,139,513;5,070,215;5,710,302;5,714,557和5,908,906中所述的硅氧烷单体。它们也可以包括各种增韧剂、着色剂、紫外线阻断剂和湿润剂。它们可以用稀释剂例如美国专利No.6,020,445中所述的伯醇、或仲醇、或叔醇来制作。所引用的专利全部以其全文列为本文参考文献。
在一种较好实施方案中,本发明的眼镜是通过使一种大分子单体与一种包括硅酮系单体和亲水单体的反应混合物反应制作的。该大分子单体可以通过使一种甲基丙烯酸酯或丙烯酸酯和一种硅酮在一种基团转移聚合(“GTP”)催化剂的存在下化合来制作。这些大分子单体是各种单体的共聚物。它们可以以这些单体按各异的嵌段或按总体上无规分布结合在一起这样一种方式生成。这些大分子单体还可以是直链的、支链的、或星形的。支链结构是诸如当该大分子单体中包括聚甲基丙烯酸酯或可交联单体如甲基丙烯酸3-(三甲基甲硅烷氧基)丙酯时形成的。
可以用来制作GTP聚合物的引发剂、反应条件、单体、和催化剂详见“Group-Transfer Polymerization”by O.W.Webster,in Encyclopedia of Polymer Scienceand Engineering Ed.(John Wiley & Sons)p.580,1987。这些聚合是在无水条件下进行的。羟基官能单体像HEMA可以作为其三甲基甲硅烷氧基酯掺入,并在聚合后水解以形成游离羟基。GTP提供了在该链上装配大分子单体并对分子量分布和单体分布进行控制的能力。然后,可以使这种大分子单体与主要为聚二甲基硅氧烷(较好单甲基丙烯酰氧丙基封端聚二甲基硅氧烷(“mPDMS”))和亲水单体的反应混合物反应。较好的mPDMS有下式:
式中b=0~100、较好8~10;R58是一个含有烯键不饱和片段的一价基团,较好是一个含有苯乙烯基、乙烯基、或甲基丙烯酸根片段的一价基团,更好是一个甲基丙烯酸根片段;每一个R59都独立地是一个一价烷基或芳基基团,该基团还可以有醇、胺、酮、羧酸或醚基团取代,较好是无取代的一价烷基或芳基基团,更好是甲基;且R60是一个一价烷基或芳基基团,该基团还可以有醇、胺、酮、羧酸或醚基团取代,较好是无取代的一价烷基或芳基基团,更好是一个可以包括杂原子的C1-10脂肪族或芳香族基,还要好是C3-8烷基基团,最好是丁基、尤其仲丁基基团。
较好的大分子单体成分包括mPDMS、3-甲基丙烯酰氧基丙基三(三甲基甲硅烷氧基)甲硅烷(“TRIS”)、甲基丙烯酸甲酯、HEMA、DMA、甲基丙烯腈、甲基丙烯酸丁酯、甲基丙烯酸2-羟基丙-1-酯、2-羟基乙基甲基丙烯酰胺和甲基丙烯酸。甚至更好的是,该大分子单体是从HEMA、甲基丙烯酸甲酯、TRIS、和mPDMS的反应混合物制作的。最好的是,该大分子单体是从包含、基本组成的、或组成为约19.1摩尔HEMA、约2.8摩尔甲基丙烯酸甲酯、约7.9摩尔TRIS、和约3.3摩尔单甲基丙烯酰氧丙基封端单丁基封端聚二甲基硅氧烷的反应混合物制作的,而且是通过使上述材料与约2.0摩尔/摩尔的3-异丙烯基-ω,ω-二甲基苄基异氰酸酯用二月桂酸二丁基锡作为催化剂进行反应完成的。
硅酮水凝胶的反应性成分典型地是疏水硅酮与非常亲水成分的组合。由于这些成分往往因其极性的差异而不可混溶,因而特别有利的是把疏水硅酮单体与亲水单体尤其那些有羟基基团者的组合并入该大分子单体中。然后,该大分子单体可以用来兼容那些掺入最后反应混合物中的另外硅酮和亲水单体。这些共混物典型地也含有稀释剂,以进一步兼容和增溶所有成分。较好,该硅酮系水凝胶是通过使下列单体混合物反应制作的:大分子单体;一种Si7-9单甲基丙烯酰氧基封端聚二甲基硅氧烷;和亲水单体,以及少量添加剂和光引发剂。更好的是,该水凝胶是通过使大分子单体、一种Si7-9单甲基丙烯酰氧基封端聚二甲基硅氧烷、TRIS、DMA、HEMA、和二甲基丙烯酸四甘醇酯(“TEGDMA”)反应制作的。最好的是,该水凝胶是从(所有数量都是作为该组合物总重量的重量百分率计算的)大分子单体(约18%)、Si7-9单甲基丙烯酰氧基封端聚二甲基硅氧烷(约28%)、TRIS(约14%)、DMA(约26%)、HEMA(约5%)、TEGDMA(约1%)、聚乙烯基吡咯烷酮(“PVP”)(约5%)、余额包含少量添加剂和光引发剂的反应制作的,且该反应是在20wt%二甲基-3-辛醇稀释剂的存在下进行的。
眼镜表面可以用任何一种方便的方法涂布一种可溶胀涂料,例如施用一种适用亲水涂料。这些涂料可以用任何一种方便的方法施用。较好的亲水涂料包括但不限于聚(丙烯酸),聚(甲基丙烯酸),聚(马来酸),聚(衣康酸),聚(丙烯酰胺),聚(二甲基丙烯酰胺),甲基丙烯酸、丙烯酸、马来酸、衣康酸与任何反应性乙烯基单体的嵌段或无规共聚物,羧甲基化聚合物例如羧甲基纤维素,葡聚糖,聚乙烯醇,聚环氧乙烷,聚(HEMA),聚磺酸盐,聚硫酸盐,聚内酰胺,聚乙醇酸,聚胺等,及其混合物。更好,该涂料是聚(丙烯酸)、聚(甲基丙烯酸)、聚(二甲基)丙烯酰胺、聚(丙烯酰胺)、或聚(HEMA)。最好使用聚(丙烯酸)、聚(丙烯酰胺)、或聚(HEMA)。
本发明的眼镜可以用任何已知的接触眼镜制造工艺制作。较好,该眼镜是通过使眼镜组合物光致固化并向固化的眼镜上施用一种涂料来制作的。已知有各种工艺可在接触眼镜生产中用于使反应混合物模塑,包括旋转浇铸和静态浇铸。较好的本发明接触眼镜生产方法是硅酮水凝胶直接模塑法,这是经济的并使得能准确控制该水合透镜的最终形状。对于这种方法来说,把该反应混合物置于一种有最终所希望硅酮水凝胶即水溶胀聚合物的形状的模型中,并使该反应混合物遭遇到能使该单体聚合的条件,产生一种呈最终所希望产品的近似形状的聚合物。这样的聚合的条件是业内众所周知的。该聚合物混合物任选地可以用一种溶剂然后用水处理,产生有类似于原来模塑聚合物物品的尺寸和形状的最终尺寸和形状的硅酮水凝胶。这种方法可以用来形成接触眼镜,其进一步描述见美国专利No.4,495,313、4,680,336、4,889,664和5,039,459,这些专利以其全文列为本文参考文献。

透镜形成-实施例1~18
用于生产眼镜的大分子单体的制备是在氮气氛围下在14℃向13.75ml间氯苯甲酸四丁铵(“TBACB”)在四氢呋喃(“THF”)中的1M溶液中添加191.75g 1-三甲基甲硅烷氧基-1-甲氧基-2-乙基丙烯、30.0g二(二甲胺基)甲基甲硅烷、61.39g对二甲苯、154.28g甲基丙烯酸甲酯、和4399.78g THF中的1892.13g甲基丙烯酸2-(三甲基甲硅烷氧基)乙酯。用一段260分钟的时间添加30ml另外的TBACB在THF中的溶液(0.40M),在此期间让该反应混合物能够放热,然后冷却到30℃。甲基丙烯酸2-(三甲基甲硅烷氧基)乙酯添加后60分钟,添加467.56g甲基丙烯酸2-(三甲基甲硅烷氧基)乙酯、3636.6gnPDMS、3673.84g TRIS和20.0g二(二甲胺基)甲基甲硅烷的溶液,让该混合物能够放热,然后在2小时内冷却到30℃。然后添加10.0g二(二甲胺基)甲基甲硅烷、154.26g甲基丙烯酸甲酯、和1892.13g甲基丙烯酸2-(三甲基甲硅烷氧基)乙酯的溶液,再次使该混合物能够放热。2小时后,添加2加仑无水THF,随后,在使该溶液冷却到34℃之后添加439.69g水、740.6g甲醇和8.8g二氯乙酸的溶液。该混合物回流4.5小时,用油浴在110℃加热,在135℃蒸出挥发物,并添加甲苯以有助于脱水,直至达到110℃的蒸气温度。
使反应烧瓶冷却到110℃,添加443g二甲基间异丙烯基苄基异氰酸酯和5.7g二月桂酸二丁基锡的溶液。使该混合物反应3.5小时,然后冷却到30℃。在减压下蒸发甲苯,得到米色、无水、蜡状、反应性在大分子单体。

接触眼镜的形成是向TOPAS模腔中添加大约0.10g该眼镜材料,并使该材料固化大约1200秒。聚合是在氮气吹扫下进行的,是用5mWcm2以Andover Corp.420 PS10-25 AM3956502滤光器产生的紫外光进行光引发的。固化完成后将模型打开,使透镜释放到水与异丙醇的1∶1共混物中,并在异丙醇中浸提以除去残留单体和稀释剂。这些透镜在生理硼酸盐缓冲食盐水中平衡。使浸提过的透镜在45℃的、添加了0.1%1-[3-(二甲胺基)丙基]-3-乙基碳化二亚胺盐酸盐的、1.0%25万分子量聚(丙烯酸)的硼酸盐缓冲食盐水溶液中浸渍,制备了有涂层的透镜。搅拌大约30分钟后,用硼酸盐缓冲食盐水溶液漂洗这些透镜。
透镜测试
所有透镜(眼镜)的离体工具痕迹测定都是将每个透镜揩吸干,将该透镜置于一个钢质44.75D(7.55mm半径)角膜散光计校正标准上,用一盏在最大照度时有16~40×放大的蔡司狭缝灯(Model30SL/M,电源31 04 58)来寻找工具痕迹的存在与否。除实施例1~18的透镜外,还测试了实施例19和20的透镜,即用Lotrafilcon A制作的、分别无涂层和有涂层的FOCUSNIGHT&DAY日常佩戴眼镜。下表列出了本研究的结果。
