The cornea is the transparent membrane of the eye that covers the iris and the pupil .
Being a very delicate area with limited self-repairing possibilities, an injury could also have serious consequences and make the so-called corneal transplant necessary.
Corneal transplantation, or keratoplasty, is the surgical procedure by which total or partial replacement of the original cornea, severely damaged, is performed with a similar healthy element, coming from a recently deceased donor or of synthetic origin.The following is a series of questions related to keratoplasty, which the prospective cornea transplant recipients usually ask the doctor who will treat them:
- Is it a painful procedure?
No, as local or general anesthesia is required (depending on the situation).
However, discomfort (such as "sand in the eyes") or pain may be felt in the first few days after surgery. In the first case, it is a passing sensation; in the second, instead, it is better to consult the doctor, as a precaution.
- How long after transplantation can you return to a normal life?
In the first post-operative weeks, it is recommended to avoid efforts, such as lifting weights or pushing excessively during defecation.
The healing time of the cornea is very long: total healing could take place even in 18-24 months. During this time, care must be taken to protect the eye operated from any external "insult".
- What is the average duration of transplanted corneas?
The endothelial cells that constitute the corneas (whether normal or transplanted) are destined to a progressive decay. Generally, transplanted corneas maintain their transparency for about 25 years. As in every circumstance, there are exceptions: some transplanted corneas, in fact, resist for even forty years.
- After a month and a half the sight is still tarnished, is it normal?
Yes, as it takes several months (usually 6) before the "new" cornea reaches the desired transparency.
- What is suture remodeling?
This is an adjustment of the surgical sutures, applied to the transplanted cornea. It serves to accelerate visual improvement. The procedure is quick and painless and involves the use of an anesthetic and eye drops.
