Description
本发明涉及眼部医疗器件领域,具体地,涉及应用于可折叠人工晶体的单体、聚合物、制备方法及其用途。
眼部医疗器件,例如人工晶体、隐形眼镜、人工角膜、角膜内环或角膜内透镜等,是能植入眼内的人造材料或透镜,主要用于取代因白内障等疾病而变浑浊的人眼中的天然晶体,或者用于通过佩戴、屈光手术等手段以纠正人眼的视力。上述眼部医疗器件通常是由一个圆形光学部和周边支撑物组成。其中,光学部是由透明的高分子材料制成的。由软性聚合物制成的人工晶体,也经常被称作可折叠人工晶体,其可以在折叠或卷曲后通过一个较小的手术切口植入眼内,可折叠人工晶体进入眼睛后能自动展开。目前的人工晶体多为可折叠人工晶体,目前用于制备可折叠人工晶体的软性材料多为聚(甲基)丙烯酸酯聚合物。
然而,目前用于制备眼部医疗器件的聚合物、单体以及其制备方法仍有待改进。
发明内容
本申请是基于发明人对以下事实和问题的发现和认识而做出的:
目前的可折叠人工晶体,普遍存在难以通过目前的手术技术所能够实现的小尺寸切口进行植入的问题。具体的,随着白内障手术技术的发展,在不考虑植入的眼部医疗器件(如人工晶体)的尺寸的条件下,已经可以做到通过较小的切口实现手术。然而目前的眼部医疗器件,则难以实现在保证其器件性能不受影响的条件下,折叠至上述手术切口可以实现的尺寸。因此,诸如可折叠人工晶体等眼部医疗器件在一定程度上妨碍了小切口手术的实施。发明人经过深入研究以及大量实验发现,这主要是由于目前用于制备眼部医疗器件聚合物的折光率以及力学性能难以满足需求而导致的。对于可折叠人工晶体,如需在能够折叠至较小尺寸的前提下保证其光学性能,则要求制备人工晶体的材料同时具有较好的折光率以及力学性能:当用于制备眼部医疗器件的聚合物的折光率不够高时,则需要通过增加眼部医疗器件的厚度来满足器件对于光学性能的要求,反之,如要求眼部医疗器件具有足够纤薄的厚度,则用于制备该器件的聚合物需要具有足够高的折光率;此外,由于可折叠人工晶体需要在进入眼睛后自动展开,因此需要制备人工晶体的聚合物在具有足够的抗冲击性能,保证人工晶体在使用过程中不会折断的同时,又需要具有适当的弹性,使周边支撑物能够支持光学部稳定在人眼内不发生移动,且不会由于展开过程过于剧烈而对人眼造成损伤。
本发明旨在至少一定程度上解决以上相关技术中的技术问题之一。为此,本发明提出一种单体。该单体的结构如式(I)所示:
其中,
R1为氢或甲基;
R2为烷基;
R3分别独立地为-L-M,其中L为一个键、亚烷基、-O-、-NR-、-C(=O)-、-C(=O)-NR-、-S(=O)2-或-S(=O)2–NR-,M为氢、烷基、卤素、氰基、羟基、硝基、醛基、卤代烷基、烷氧基、烷硫基、烷氨基、烯基、炔基、芳基、芳基烷基或芳氧基;各R独立地为氢、羟基、C1-6烷基、C2-6烯基、C2-6炔基、C1-6烷氧基、C6-10芳基或C6-10芳基C1-6烷基;和
n为0、1、2、3、4或5。
含有该单体的聚合物具有较高的折光率,且力学性能优良,使用本发明所述单体制备的聚合物折光率高、透过率好、力学性质优良,特别适合用于制备眼部医疗器件,能够满足制备纤薄、可折叠人工晶体的要求。
本发明提出的单体以及聚合物的折光率不低于1.53,在可见光400nm-800nm范围内,光谱透过率不低于80%。
本发明提出的聚合物具有较高的拉伸强度、适当的弹性模量以及较大的断裂伸长率,采用本发明提出的聚合物制备的可折叠人工晶体,既不会由于张开过于剧烈而损伤人眼,也不会由于力学性能不佳而影响使用效果。
本发明还提出制备所述单体的方法,该方法包括使式(II)所示化合物与式(III)所示化合物发生缩合反应:
式(II)所述化合物是由式(IV)所示化合物与式(V)所示化合物发生取代反应得到的,
其中,n、R1、R2和R3具有如本发明所述的定义;R4为-Cl、-Br、-OTs或-OMs。该方法操作简单、收率高,特别适合工业放大生产。
本发明还提出一种聚合物。构成所述聚合物的单体包括前面所述的单体。包含本发明所述单体的的聚合物折光率高、透过率好、力学性质优良,特别适合用于制备眼部医疗器件。
本发明还提出前面所述聚合物在制备眼部医疗器件中的用途。利用上述聚合物制备眼部医疗器件时,能够在较小的厚度下实现较为理想的器件性能,有利于实现利用较小的手术切口实现眼部医疗器件的植入。
最后,本发明还提出一种制备前面所述的聚合物的方法。该方法包括:对原料混合物进行梯度式加热处理,以便获得所述聚合物,其中,所述原料混合物含有本发明所述的单体,以及任选地选自式(VI)所示的化合物、交联剂、引发剂以及紫外吸收剂的至少之一。

按照以下条件,对上述实施例23-53和59~61获得的聚合物的光谱透过率进行测试:室温下,通过安捷伦Cary60紫外可见分光光度计测试材料在200nm-800nm光波范围内的光谱透过率。
测试结果表明,实施例23-53和59~61的聚合物在可见光范围内,光谱透过率的最大值均高于80%。表2列出了聚合物A-1~A-34的紫外光透过截止波长(紫外区透过率为1%处对应波长以及紫外区透过率为10%处对应波长)和光谱透过率(最大值)。由表2可以看出,下列聚合物均具有较高的光谱透过率。并且,在紫外光区透过率为10%对应的波长不低于360nm,表明下列聚合物具有较好的紫外光拦截效果。
表2:实施例25~53和59~61所得聚合物的光谱透过率
聚合物力学性质的测定
拉伸测试:用裁刀将材料裁成预设的矩形试样(有效尺寸:宽0.83300mm,厚0.40000mm,长14.00000mm),在室温26℃,空气湿度77%的条件下用INSTRON 3367型材料试验机测试,测试位移速率500.00000mm/min。测试表明,下列聚合物均具有较为良好的力学性能,适于制备人工晶体。由于下列聚合物同时还具有较好的光谱透过率以及折光率,因此便于利用下列聚合物形成纤薄且光学性能良好
的可折叠人工晶体。
