Abstract
Description
概して、蛇行性経路を画定する、離間関係で配置される複数のパターン表面要素を外面上に有する、眼内インプラントは、流体流れまたは流体中に懸濁させられる粒子流れを制御し、もしくは細胞の接着、成長または移動を阻止するように適合される。具体的には、眼内レンズと眼の後嚢の表面との間に埋め込まれる眼内インプラントは、眼の後嚢混濁化を低減させるように構造的障壁を提供することによって、白内障手術後に残存水晶体上皮細胞の成長また移動を阻止する。
視覚障害型白内障は、世界中で予防可能な失明の主要な原因である。現在、白内障の唯一の公知の処置は、罹患した眼の混濁した水晶体の外科的除去、ならびに典型的には眼内レンズオプテックおよびハプティクス(「IOL」)を含む人工眼内レンズとの置換である。IOL埋込を伴う白内障手術の技術的進歩は、白内障手術を最も効果的な外科的手技の1つにしてきた。
したがって、本発明の広い目的は、流体流れ、流体流れ中に懸濁させられる粒子流れを制御し、または細胞の成長もしくは移動を阻止するように適合される、複数の表面要素を横断する蛇行性経路を画定する、離間関係で配置される複数のパターン表面要素(「表面要素」とも称される)を含む外面を有する、眼の局所領域中に埋め込むために構成される生体適合性眼内インプラントを提供することであり得る。
概して、蛇行性経路を画定する、離間関係で配置される複数のパターン表面要素を外面上に有する、眼内インプラントは、流体流れ、流体中に懸濁させられる粒子流れを制御し、または細胞の成長もしくは移動を阻止する。具体的には、IOLと眼の後嚢の表面との間に埋め込まれる眼内インプラントは、眼のPCOを低減させるように構造的障壁を提供することによって、白内障手術後に残存水晶体上皮細胞の成長または移動を阻止する。具体的には、IOLと眼の後嚢の表面との間に埋め込まれる眼内インプラントは、眼のPCOを低減させるように構造的障壁を提供することによって、白内障手術後に残存水晶体上皮細胞の移動を阻止する。
「1つの」(「a」または「an」)エンティティは、1つまたはそれを上回るそのエンティティを指し、例えば、「1つのポリマー」は、これらの組成物のうちの1つまたはそれを上回るもの、もしくは少なくとも1つの組成物を指す。したがって、「1つの」(「a」または「an」)、「1つまたはそれを上回る」、および「少なくとも1つの」という用語は、本明細書で同義的に使用されることができる。さらに、「から成る群から選択される」という用語は、要素のうちの2つまたはそれを上回るものの組み合わせを含む、以降に続くリスト内の要素のうちの1つまたはそれを上回るものを指す。
