परिचय

What is Cornea Transplantation (Keratoplasty)?

Cornea transplantation, also known as keratoplasty, is a surgical procedure to replace a damaged or diseased cornea with a healthy donor cornea. The cornea is the clear, dome-shaped surface at the front of the eye that helps focus light onto the retina. When it becomes cloudy, scarred, or irregularly shaped due to injury, infection, or disease, vision can become significantly impaired. Corneal transplant surgery restores vision, reduces pain, and improves the overall health of the eye.

 

 

When is a Corneal Transplant (Keratoplasty) Needed?

A corneal transplant is required when the cornea becomes so damaged that it no longer functions properly. Common conditions that may necessitate a transplant include:

  • keratoconus

    – A progressive thinning of the cornea that causes it to bulge into a cone shape.

  • कॉर्नियल स्कारिंग

    – Due to infections, trauma, or chemical burns.

  • Fuchs’ Dystrophy

    – A condition where the inner layer of the cornea deteriorates, leading to swelling and vision loss.

  • कॉर्नियल अल्सर

    – Severe infections or ulcers that leave the cornea damaged.

  • Previous Failed Corneal Transplant

    – Some patients may require a repeat transplant if the initial one fails.

  • Hereditary Eye Conditions

    – Some genetic disorders can affect corneal health.

कॉर्निया प्रत्यारोपण सर्जरी कौन करता है?

Corneal transplant surgery is performed by an ophthalmologist specializing in corneal diseases and surgeries. These highly trained eye surgeons carefully assess each patient’s condition and determine the best type of transplant procedure.

What is the Procedure of Cornea Transplant (Keratoplasty)?

Corneal transplant surgery is a delicate procedure that follows these steps:

  • Pre-Surgical Assessment:

    The patient undergoes a detailed eye examination, including corneal measurements and imaging.

  • Anesthesia Administration:

    The procedure is usually performed under local or general anesthesia.

  • Removal of the Damaged Cornea:

    The surgeon carefully removes the affected portion of the cornea using precision instruments.

  • Donor Cornea Placement:

    The healthy donor cornea is prepared and positioned in place.

  • Suturing or Fixation:

    The new cornea is secured using fine stitches or a laser-based attachment, depending on the technique used.

  • ऑपरेशन के बाद की देखभाल:

    Medications and follow-up visits ensure the success of the transplant and prevent rejection.

कॉर्निया प्रत्यारोपण के प्रकार क्या हैं?

There are several types of corneal transplant procedures, each suited for different conditions:

  • Penetrating Keratoplasty (PK):

    A full-thickness transplant where the entire cornea is replaced.

  • Deep Anterior Lamellar Keratoplasty (DALK):

    Only the outer layers of the cornea are replaced, preserving the inner layers.

  • Endothelial Keratoplasty (DSAEK/DMEK):

    A selective replacement of the cornea’s innermost layer, often used for conditions like Fuchs’ dystrophy.

  • Artificial Cornea Transplant (Keratoprosthesis):

    Used in cases where donor corneas are not an option.

Risk Factors of Cornea Transplantation

While corneal transplant surgery has a high success rate, some risks include:

  • Rejection of the Donor Cornea

    – The immune system may attack the transplanted tissue.

  • Infection

    – Post-surgical infections can occur if proper care is not taken.

  • Increased Intraocular Pressure (Glaucoma)

    – A possible complication leading to optic nerve damage.

  • दृष्टिवैषम्य (अस्थिग्मैटिज़्म)

    – Irregular curvature of the cornea, sometimes requiring glasses or contact lenses.

  • Swelling or Cloudiness

    – Can affect vision post-surgery.

How to Prepare for a Cornea Transplant?

Patients undergoing corneal transplant surgery should follow these steps:

  • Undergo a comprehensive eye examination.

  • Discuss medications with their doctor, as some may need to be stopped before surgery.

  • Arrange for someone to assist them post-surgery.

  • Follow pre-operative fasting instructions if required.

What to Expect After Cornea Transplant Surgery?

Recovery from cornea transplant surgery varies by individual and procedure type. Some general expectations include:

  • Initial Healing Period:

    Vision may be blurry for a few weeks as the eye adjusts.

  • Use of Eye Drops and Medications:

    Steroid eye drops help prevent rejection.

  • Avoiding Strenuous Activities:

    Activities such as heavy lifting and rubbing the eyes should be avoided.

  • Regular Follow-Up Visits:

    Monitoring is crucial to detect any complications early.

How to Take Care of Your Eyes After a Cornea Transplant?

To ensure a successful recovery, patients should:

  • Follow the prescribed medication schedule.

  • Protect their eyes from dust, wind, and bright sunlight.

  • Avoid swimming and exposure to contaminated water.

  • Wear protective glasses to prevent accidental injury.

  • Report any sudden pain, redness, or vision changes immediately.

What Are the Alternatives to Cornea Transplant?

For some patients, alternative treatments may be considered before opting for corneal transplant surgery:

  • Corneal Cross-Linking:

    Strengthens the cornea in keratoconus patients to slow progression.

  • Specialty Contact Lenses:

    Scleral lenses can help improve vision in certain corneal conditions.

  • Laser Treatments:

    Procedures like PTK (Phototherapeutic Keratectomy) can remove superficial corneal scars.

  • Artificial Cornea (Keratoprosthesis):

    For severe cases where donor transplants are not viable.

Frequently Asked Questions (FAQs) about Cornea Transplantation

What Are the Success Rates and Longevity of Corneal Transplants?

Corneal transplants have a high success rate, with 90% of transplants remaining clear and functional after one year. The longevity of the transplant depends on factors such as the patient’s overall health, adherence to post-operative care, and the presence of underlying conditions. A well-maintained corneal graft can last 10–20 years or even longer.

The cost of a corneal transplant in India varies based on hospital facilities, surgeon expertise, and the type of keratoplasty performed. On average, the cost ranges from ₹50,000 to ₹2,50,000. Patients should also consider post-operative care expenses, including medications and follow-up visits.

While a corneal transplant can significantly improve vision, it may not always restore perfect vision. Patients may still need glasses or contact lenses for fine-tuned vision correction. Success depends on factors like the condition being treated, post-operative healing, and any underlying eye diseases.

The recovery period for a corneal transplant varies depending on the type of surgery. Initial healing takes a few weeks to a few months, but full visual stabilization may take up to a year. Patients need regular follow-ups and must follow the prescribed medication regimen to ensure proper healing.

Corneal transplantation is performed under local or general anesthesia, so the patient does not feel pain during surgery. Post-surgery, mild discomfort, irritation, or a foreign body sensation may be experienced, which is manageable with prescribed medications.

Corneal transplantation is generally safe, but risks include graft rejection (10-20% cases), infections, increased eye pressure (glaucoma), astigmatism, and corneal haze. Most complications can be managed with prompt medical care and regular follow-ups to ensure successful healing and long-term vision improvement.

A transplanted cornea can last 10 to 20 years, but longevity varies based on patient health and post-surgical care. Some patients may require a second transplant if the graft fails or deteriorates over time. Following the surgeon’s recommendations can help maximize graft survival.
