If the cornea is detached, the cornea generally has a more serious ulcer that has broken down. This surgery is usually considered for a corneal transplant, and if the lamina cribrosa is transplanted, the cost of the surgery is about $7,000-8,000, and if the full corneal transplant is generally more than $10,000. However, corneal material is now donated and must be registered with the Red Cross before an appointment can be made for the cornea to be treated. Overall there are two parts to a corneal transplant, one is the cost of the corneal transplant, and the other is the follow-up eye drops, which require immunosuppressive drugs and long-term use for about a year, the cost of the eye drops is about 2,000-3,000 yuan a year, but there is a certain probability that the corneal transplant will not be successful.
