Application of bio-artificial cornea and its research progress

摘要

Cornea is a layer of transparent film which located in the forefront of the eye.In the world,more than 30%blindness patients were caused by corneal disease.Corneal transplantation is the only effective means of treatment of corneal blindness.Owing to a serious shortage of donor cornea,China’s annual eye bank can only provide a small amount of surgery used cornea.Therefore,seeking a good equivalent corneal replacement is an important way to solve the problem of insufficient donor cornea.At present,in vitro reconstruction of the tissue engineering cornea can be used as a mild corneal equivalent substitute to solve the problem of insufficient donor cornea.We may be able to rebuild a good corneal replacement for corneal transplantation.And the corneal replacement can be acting as ideal grafts for corneal transplantation in patients with severe corneal injury in the future.
