Keratoplasty, Cornea Transplantation (Comeal Graft)

Keratoplasty, also known as corneal transplantation, is an eye surgery that involves replacing diseased areas of the cornea with a donor corneal graft. This procedure can be performed either by replacing all layers of the cornea (penetrating keratoplasty), or only its superficial layers, leaving the deep layers intact (layered (non-penetrating) keratoplasty). In the latter case, the thickness of the replaced corneal layer decreases accordingly.

Reasons why keratoplasty may be needed include a number of conditions, such as keratoconus (where the cornea becomes conical), scarring of the cornea after injury or infection, corneal dystrophy, and others. Keratoplasty may also be necessary to correct the risk of vision loss or to transplant a cornea that does not respond to treatment.

The keratoplasty procedure is usually performed in a hospital or clinic, and can be performed under general or local anesthesia. Before surgery, the patient may be prescribed medications to help prevent infection and reduce the risk of transplant rejection. The surgery itself can take anywhere from a few hours to a full day, depending on the type of keratoplasty.

After surgery, the patient may be prescribed anti-inflammatory and decongestant medications, as well as eye drops to speed up healing. In most cases, patients can notice improved vision within a few days after surgery, but full recovery may take several months.

Keratoplasty is a relatively safe procedure, but like any other surgical procedure, it may come with some risks and complications. These risks may include infection, graft rejection, increased pressure inside the eye, and others.

In general, keratoplasty is an effective treatment for many diseases of the cornea. Thanks to modern technology and techniques, most patients who undergo this procedure notice significant improvements in vision and quality of life.

Keratoplasty, Cornea Transplantation (Comeal Graft) is a procedure that can help people suffering from various diseases of the cornea of ​​the eye, restore vision and improve the quality of life. The cornea is the clear, convex part of the eye that covers the pupil and iris. It plays a key role in the process of focusing light on the retina. When the cornea becomes damaged or diseased, it can lead to significant vision impairment and even complete loss of visual function.

One of the methods of treating a damaged cornea is keratoplasty, which can be performed as penetrating keratoplasty or lamellar keratoplasty.

Penetrating keratoplasty, or full-thickness penetrating keratoplasty (PKP), involves removing the entire damaged cornea and replacing it with a full-thickness donor cornea. This procedure is performed in severe cases of corneal disease such as deep ulcers, keratoconus and hereditary corneal diseases.

Lamellar keratoplasty (lamellar keratoplasty) is a method in which diseased layers of the cornea are replaced only with donor layers, leaving intact layers in place. In this case, depending on the depth of the corneal damage, only the superficial layers (the first 2/3 of the thickness) or deeper layers can be replaced. This treatment is typically used to treat milder forms of corneal disease, such as superficial ulcers and some cases of keratoconus.

However, like any other surgical procedure, keratoplasty has its risks and limitations. During the intervention, infection, graft rejection, damage to eye tissue, hemorrhage and other complications may occur. In addition, keratoplasty may not be effective in severe cases of corneal disease when the lesions are too deep and extend throughout the thickness of the cornea.

However, keratoplasty remains one of the most effective treatments for corneal diseases, and many patients experience significant improvement in vision after this procedure. As with any case, it is important to discuss the risks and benefits of keratoplasty with your doctor and make an informed decision about whether the procedure is right for you.

Keratoplasty can be performed either in a traditional format, using a microscope and hand instruments, or in a modern format, using laser technology. Laser keratoplasty can be more precise and cause less damage to healthy tissue around the damaged area of ​​the cornea. This can reduce the risk of complications and speed up the process of vision recovery.

It is also important to note that to perform keratoplasty, you must have a donor cornea. Cornea donors must consent to the donation and must undergo a series of medical tests to ensure there are no infections or other diseases.

Overall, Keratoplasty or Comeal Graft is an important treatment method for various corneal diseases that can help patients restore vision and improve their quality of life. However, like any other medical procedure, keratoplasty has its risks and limitations and should only be performed after a thorough evaluation of the patient and discussion of all possible treatment options with the physician.

Keratoplasty, or corneal transplant, is a treatment for corneal diseases that uses living or artificial tissue to replace a damaged or weakened cornea.

The cornea is the transparent outer layer of the eyeball that focuses light and protects the eye from
