世界上超过1000万人的眼盲是由角膜疾病引起的,为导致眼盲的第二大原因,仅次于白内障。角膜盲患者80%可以通过角膜移植手术脱盲。然而,传统的角膜移植手术有其两大弊端,一是角膜供体的来源困难,二是手术成功率低。因此人工角膜的出现及应用为角膜盲患者带来了希望的曙光。 Eye blindness in more than 10 million people in the world is caused by corneal disease, the second largest cause of blindness, after cataract. Eighty percent of patients with corneal blindness can become blind by a corneal transplant. However, the traditional corneal transplantation has its two major drawbacks, one is the source of corneal donor difficulties, and second, the success rate of surgery is low. Therefore, the emergence and application of artificial corneal blind patients brought hope of the dawn.
