PROBLEM TO BE SOLVED: To provide corneal implants that will allow for the efficacious transmission of nutrients from the inner surface of a corneal implant to the outer surface, so that tissue in the outer portion of the cornea is properly nourished.SOLUTION: The corneal implant includes the body formed of an optically clear, biocompatible material with a refractive index substantially similar to the refractive index of the cornea, being solid, and formed with "x" and "y" axes oriented at 90° relative to each other, has a diopter power along one axis being greater than that along the other axis, useful for correcting astigmatism, and further includes markers 76a, 76b to mark and identify the direction of the implant 94 during implantation.COPYRIGHT: (C)2010,JPO&INPIT【課題】角膜インプラントの内表面から外表面への栄養分の効率的な移動を可能にし、その結果、適切な栄養分を角膜の外側部分の組織にもたらす角膜インプラントを提供する。【解決手段】角膜組織の屈折率と実質的に同じ屈折率を有する光学的に透明な生体適合性材料から形成され、非中空であって、相互に90°で向き合う「x」および「y」軸で形成された本体、及び乱視矯正に有効な、一方の軸上よりも他方の軸上の方が大きいジオプター度数、移植中にインプラント94の方向を助力するマーカー76a,76bをさらに含む角膜インプラント。【選択図】図20
