Corneal Transplant

Understanding the Cornea 

The cornea is the clear, dome-shaped surface that covers the front of the eye. It plays a crucial role in focusing light onto the retina, which is essential for clear vision. Any damage or disease affecting the cornea can significantly impact your vision and overall eye health. 

Common Corneal Conditions 

1. Keratoconus

Keratoconus is a progressive eye disease where the cornea thins and bulges into a cone-like shape, causing distorted vision. Symptoms include blurred vision, sensitivity to light, and frequent changes in eyeglass prescriptions. Treatment options range from corrective lenses to corneal cross-linking and, in severe cases, corneal transplant. 

2. Corneal Infections

Corneal infections, or keratitis, can be caused by bacteria, viruses, fungi, or parasites. Symptoms include redness, pain, blurred vision, discharge, and light sensitivity. Prompt medical treatment is crucial to prevent scarring and vision loss. 

3. Corneal Dystrophies

These are a group of genetic, often progressive, disorders that affect the cornea. They cause the gradual accumulation of abnormal material in the cornea, leading to cloudy vision and other symptoms. Common types include Fuchs’ dystrophy and lattice dystrophy. 

4. Corneal Ulcers

A corneal ulcer is an open sore on the cornea, typically resulting from an infection. It can cause severe pain, redness, discharge, and reduced vision. Immediate medical attention is necessary to treat the infection and prevent complications. 

5. Corneal Scarring

Scarring can occur due to injury, infection, or previous eye surgery, leading to vision impairment. Depending on the severity, treatment options may include medications, laser therapy, or corneal transplant. 

Corneal Transplant 

When the cornea becomes damaged or diseased to the point where vision is significantly impaired and cannot be corrected with other treatments, a corneal transplant may be necessary. At Netrodaya, we offer various types of corneal transplants to restore vision and improve quality of life. 

Types of Corneal Transplants 

1. Penetrating Keratoplasty (PK) This is a full-thickness transplant where the damaged cornea is replaced with a healthy donor cornea. It is typically used for advanced keratoconus, severe corneal scarring, and certain corneal dystrophies. 

1. Endothelial Keratoplasty (EK) This partial-thickness transplant involves replacing only the innermost layer of the cornea, the endothelium. Types of EK include Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet’s Membrane Endothelial Keratoplasty (DMEK). EK is preferred for conditions like Fuchs’ dystrophy and other endothelial disorders. 

1. Deep Anterior Lamellar Keratoplasty (DALK) This procedure replaces the front and middle layers of the cornea while preserving the healthy endothelium. DALK is often used for keratoconus and superficial corneal scarring. 

1. Anterior Lamellar Keratoplasty (ALK) Similar to DALK, ALK involves replacing only the outer layers of the cornea. It is used for superficial corneal diseases that do not affect the endothelium. 

The Corneal Transplant Procedure 

1. Pre-Operative Assessment A thorough pre-operative evaluation is conducted, including detailed eye examinations, imaging tests, and a review of your medical history. This ensures that you are a suitable candidate for the procedure and helps in planning the surgery. 

1. Donor Cornea The donor cornea is sourced from an eye bank and thoroughly screened to ensure its suitability and safety for transplantation. 

1. Surgery The transplant procedure is performed under local or general anesthesia. The damaged portion of your cornea is carefully removed and replaced with the healthy donor cornea, which is then secured with fine sutures. 

1. Post-Operative Care After surgery, you will need to use prescribed medications to prevent infection and reduce inflammation. Follow-up visits are crucial to monitor the healing process and ensure the success of the transplant. Sutures may be removed gradually over several months. 

Recovery and Aftercare 

Recovery from a corneal transplant can take several months to a year. During this period: 

• Follow-Up Visits: Regular check-ups are essential to monitor your eye’s healing and detect any signs of rejection or complications. 

• Medications: You will need to use antibiotic and anti-inflammatory eye drops as prescribed by your doctor. 

• Activity Restrictions: Avoid strenuous activities, rubbing your eyes, and exposing your eyes to irritants like dust and smoke. 

• Vision Correction: It may take some time for your vision to stabilize. Glasses or contact lenses might be needed, and in some cases, additional procedures like laser treatment can help fine-tune your vision. 

Risks and Complications 

As with any surgical procedure, corneal transplants carry some risks, including: 

• Rejection: The immune system may recognize the donor cornea as foreign and attempt to reject it. Prompt treatment can often reverse rejection. 

• Infection: Post-operative infections can occur, requiring immediate medical attention. 

• Glaucoma: Increased eye pressure can develop after surgery, potentially leading to glaucoma. 

• Astigmatism: Irregular curvature of the cornea may cause blurred vision, which can be corrected with glasses, contact lenses, or further surgery.
