Keratoprosthesis in Turkey | Types, process & recovery

Types of keratoprostheses available in Turkey

Keratoprostheses are made of transparent plastic, designed to mimic the optical characteristics of the natural cornea. Their design, size, and implantation method can vary based on the patient's needs and the medical facility. In Turkey, this procedure is performed by qualified ophthalmologists, often on an outpatient basis for rapid and effective recovery.

Several models of keratoprostheses are available in Turkey, each offering specific advantages depending on the type of corneal pathology. Some of the most common options include:

• Boston Keratoplasty: A widely used model that addresses a wide range of corneal disorders.
• Osteo-odonto-keratoplasty (OOKP): A more complex method, ideal for the most severe cases where other solutions are not viable.
• AlphaCor: Designed for long-term retention and optimal visual comfort.
• KeraKlear Prosthetic Keratoplasty: An innovative model providing an alternative for patients with advanced corneal disorders.

When to resort to a keratoprosthesis?

Keratoprostheses are generally used when conservative treatments such as rigid contact lenses, lasers, or intrastromal rings are no longer sufficient. They are indicated for patients suffering from severe corneal pathologies, such as:

• Corneal edema
• Post-traumatic or infectious scars (e.g., in cases of herpes)
• Shape abnormalities that alter the structure of the cornea

If you are facing a loss of corneal transparency or a shape irregularity that compromises your visual acuity, a keratoprosthesis can provide you with an effective alternative, restoring your eye's visual function to near-normal levels.

Preoperative examination for keratoprosthesis

Prior to any surgical procedure, a thorough preoperative examination is crucial to ensure a successful outcome. In the case of keratoprosthesis, the process begins with a consultation with a specialized ophthalmologist. During this consultation, the doctor will conduct a detailed assessment of your vision and perform specific tests to evaluate the condition of your eye.

The ophthalmologist will consider your medical history, as well as any previous eye treatments, to gain a better understanding of your situation. This comprehensive evaluation enables the doctor to discuss the potential benefits and risks of keratoprosthesis surgery with you. Once you decide to proceed, several medical and laboratory tests will be required to ensure that you are ready for surgery. These tests may include an X-ray, electrocardiogram (ECG),slit lamp examination, and B-scan or A-scan ultrasound to assess the overall health of your eye and body.

Based on the results of these tests, the practitioner will determine the appropriate date and time for the procedure.

Prerequisites for keratoprosthesis surgery

Certain conditions must be met before proceeding with keratoprosthesis surgery. Here are the selection criteria:

• Visual acuity: The patient's vision should not be better than 20/200.
• Retinal condition: The retina must be in place, and there should be no severe retraction of the optic nerve.
• Advanced glaucoma: If the patient suffers from advanced glaucoma, a more thorough evaluation may be required, and in some cases, conversion to another treatment might be considered.

This thorough examination ensures that keratoprosthesis surgery is suitable for your needs, thus maximizing the chances of success. If you are ready to take the next step and determine if you are a good candidate for this procedure, contact our specialists in Turkey to schedule your preoperative consultation.

Procedure of keratoprosthesis surgery in Turkey

On the day of the procedure, you will be welcomed at the hospital or specialized ophthalmic surgery center, where the keratoprosthesis procedure will take place. After a final physical examination to check your health status, you will be prepared for the operating room. Depending on your specific situation, the procedure will be performed under either general or local anesthesia to ensure maximum comfort and safety.

A blepharoscope will be used to keep your eye open throughout the procedure, ensuring optimal visibility for the surgeon. Ocular lubricants may also be used to prevent dryness during the procedure. Depending on the type of keratoplasty chosen, the surgery may involve either a full-thickness corneal replacement (full-thickness keratoplasty) or the placement of an intra-lamellar implant.

Specificities of Keratoprosthesis Techniques

For the AlphaCor method, a manual incision is made to create a corneal pocket. A punch is then used to open the posterior cornea, allowing the insertion of the implant into the corneal sinus. This process allows for the gradual bio-integration of the device. After several months, a second procedure is performed to remove part of the anterior cornea, thus facilitating the entry of light to the retina.

In the case of the KeraKlear keratoprosthesis, a corneal pocket is also created. After a few months, a second procedure will remove part of the anterior cornea, promoting light penetration and improving visual clarity.

Post-operative follow-up

After the surgery, a follow-up session will be scheduled a few days after the procedure. During this consultation, the doctor will check the health of your eye and adjust treatments if necessary to ensure the best possible recovery.
