Corneal transplant for Peters’ anomaly

What does it involve?

Peters’ anomaly is an inborn error in the development of the eyeball that may affect one or both eyes. Corneal transplantation involves replacing the opaque cornea with another healthy cornea from a donor. In case there are also cataracts (clouding of the crystalline lens), these are extracted during the same operation.

When is it carried out?

In cases where involvement by Peters’ anomaly is bilateral, the aim of corneal transplantation is to improve visual acuity.

What is the procedure?

Surgery indicated for the treatment of this disease is usually a corneal transplant. It is an outpatient procedure and it is done under general anaesthesia. After surgery, which lasts from 40 to 50 minutes, eye drops must be administered for several months. The child should avoid overexertion for three weeks; after this period, he or she may resume a normal routine.

At times, a significant improvement in visual acuity is achieved through surgery, although sometimes the results are less evident. For that reason, it can be difficult to decide whether or not surgery should be performed and the best moment to do it. The decision is made more complicated by the fact that it is difficult to know what small children really can see. If the patient also presents glaucoma, this must be treated.
