System's description of the present invention what improves vision or treats the disease, illness or the device of damage, method and composition of eyes. Device for eyes, for example inlay, corneal inlays and full-thickness corneal implantation material on cornea, are the material that system passes through or cover the device from effective help nerve growth. This material may include the collagen of a quantity, big what 1% (w/w), for example between about 10% (w/w) and about 30% (w/w). This material may include collagen condensate and/or second of biopolymer or water-soluble synthesized polymer body, is chemically crosslinked using EDC/NHS. This material can additionally comprise synthesized polymer body. The device system is set in what eyes, to correct or improve the vision of individual, or disease, illness or the damage for the treatment of individual eyes.本發明係描述用於改善視覺或治療眼睛之疾病、病症或損傷之裝置、方法及組合物。眼用裝置，譬如角膜上嵌體、角膜內嵌體及全厚度角膜植入物，係製自有效幫助神經生長經過或覆蓋該裝置之材料。此材料可包含一數量之膠原，大於1%(w/w)，譬如在約10%(w/w)與約30%(w/w)之間。此材料可包括膠原聚合體及/或第二種生物聚合體或水溶性合成聚合體，使用EDC/NHS化學交聯。此材料可另外包含合成聚合體。該裝置係被置於眼睛中，以矯正或改善個體之視覺，或治療個體眼睛之疾病、病症或損傷。
