Can cornea transplantation be done for the macula under the eye What is the effect?

Corneal transplantation seems to be only used for **corneal lesions, not a professional doctor is not very clear, if the landlord needs to understand the situation of corneal transplantation, you can search for the introduction of corneal transplantation in Singapore, I saw in a ** called Dada Medical News that it is very convenient to do organ transplantation, especially corneal transplantation, the average waiting time for cornea donation is one to two weeks, because Singapore has a cornea bank (SEB) dedicated to transplantation, which not only ensures the legality of the cornea**, It is also guaranteed that the patient can be transplanted with the best quality cornea. The corneas of the Singapore Eye Bank have local donations and internationally recognized US eye banks. Donor corneas can be used by both Singaporeans and non-Singaporeans who have undergone transplant surgery in Singapore.

Macular degeneration should pay attention to eye rest, which can lead to blindness. Only corneal lesions can be used for corneal transfer.

Fundus macular degeneration**, there is no specific method in modern medicine, and clinical antioxidants, vitamins, hemostatics, and optic neurotrophic drugs or cell activation preparations are often used according to the stage of the disease process. Photocoagulation should be performed early if there is neovascularization of the choroid to prevent the condition from worsening. At this time, photocoagulation can seal the existing neovascularization and cannot prevent the formation of new neovascularization, so most of the above **symptomatic**.

A variety of corneal transplants.

The eye is the window to the soul, and the cornea is the glass on this window. One of the important factors why the cornea is transparent is that there are no blood vessels in the corneal tissue, and the blood vessels terminate at the limbus of the cornea, forming a network of blood vessels, from which nutrients diffuse into the cornea. The cornea is rich in sensory nerves, mainly from the ophthalmic branch of the trigeminal nerve through the ciliary nerve to the cornea.

The cornea is rich in sensory nerves, mainly from the ophthalmic branch of the trigeminal nerve through the ciliary nerve to the cornea.

However, the corneas of the following donors cannot be used for transplantation: 1. Certain infectious diseases such as AIDS, syphilis, rabies, tetanus, leprosy, diphtheria, viral hepatitis, encephalitis, polio, etc.; 2. Malignant tumors that have invaded eye tissues, leukemia, Hodgkin's disease, etc.; 3. Certain eye diseases such as anterior segment malignant tumors, retinoblastoma, viral keratitis, corneal degeneration or scarring, glaucoma, iridocyclitis, purulent endophthalmitis and those who have undergone internal eye surgery.

So look at the macula above for corneal transplantation.

I've heard that it works well.

Hello, it is useless to do corneal transplantation in the case of high myopia and fundus slippery macula, just like the negative of the camera is not good, and it is useless to change the lens of the land, so you must first ** fundus, I hope it can help you. Cheats.

Hello, macular blindness is a fundus problem, and corneal transplantation is an ocular surface surgery, so corneal transplantation is useless in this case.

Keratoconus is generally more common in young people, and the early manifestations are aggravation of myopia astigmatism, which cannot be corrected with glasses, and RGP can be used to correct vision, but it does not prevent the progression of keratoconus, of course, some patients may not continue to develop. If the vision suddenly decreases and the cornea becomes significantly thinner and bulging in the advanced stage, a corneal transplant should be performed as soon as possible before the corneal perforation. There is currently a technique that can be used to ** keratoconus without a corneal transplant – corneal collagen cross-linking (CCL).

I have a patient who had this surgery in Beijing, and after a year of re-examination on my side, I think the results are not bad.

Hello, what do you mean by failure? What's wrong with the eyes?

The ** of keratoconus depends on the severity of the condition, generally if RGP can correct vision, corneal transplantation is not done, and if RGP can not correct vision, corneal transplantation can be considered.

What is a corneal transplant?

Corneal transplantation is an ophthalmology method that replaces the patient's existing diseased cornea with a normal cornea to restore vision to the affected eye or control corneal lesions, so as to improve vision or some corneal diseases. The cornea itself does not contain blood vessels and is in the status of "immune amnesty", so that the success rate of corneal transplantation is the first among other allogeneic organ transplants, reaching more than 90%.

In China, corneal disease is the second most common blind eye disease after cataract, so there are about 4 million to 5 million people who are disabled and blind, and more than 75% of them can regain their vision through corneal transplantation. However, due to the severe shortage of cornea donors, in the face of so many corneal blind patients, corneal donors are a drop in the bucket, and many people can only spend their lives in the dark.

So what are the conditions that require a corneal transplant? Patients with the following four types of eye diseases should be considered for timely corneal transplantation:

1. Patients with corneal disease caused by trauma and acid and alkali chemical burns, corneal scarring and corneal vascularization in the later stage of the lesion;

2. Keratitis corneal ulcers caused by bacteria, fungi or Acanthoamites, with the possibility of perforation due to poor disease control;

3. Viral keratitis, including corneal scarring in the quiescent phase and active lesions with poor long-term drug conservatism;

4. Patients with severe vision loss caused by corneal margin dissolution and destruction caused by corneal tissue lysis, corneal dystrophy and degeneration, etc.

Hello, what is the situation on your side? What's wrong with the eyes?
