The cornea plays a crucial role in maintaining clear vision by allowing light to enter the eye and focusing it on the retina. However, conditions like infections, injuries, or degenerative diseases can compromise corneal health, which leads to vision impairment or even blindness. Seeking the expertise of a Cornea Specialist in Mumbai Dr.Vinay K Agrawal (M.B.B.S., M.S. (ophthalmology), D.N.B. (Ophthalmology), Cornea Fellow, L.V.Prasad Eye Institute) is essential for diagnosing and treating corneal issues effectively. Advanced cornea treatments restore vision and improve overall eye health and quality of life.
Understanding Corneal Disorders
The cornea is a transparent, dome-shaped layer covering the front part of the eye. It serves as the eye’s primary refractive surface, helping to focus light accurately. When affected by diseases such as keratoconus, corneal dystrophy, or infections, the cornea loses its clarity and shape, resulting in distorted or blurred vision. Early diagnosis and appropriate treatment can prevent severe visual impairment and restore normal function.
Common Cornea Treatment Options
There are various treatment options available to address corneal conditions. The choice of treatment depends on the severity and type of corneal disease. Some of the most common cornea treatments include:
1. Corneal Transplantation
Keratoplasty, also known as corneal transplant surgery, becomes necessary when the cornea thins excessively or when contact lenses are no longer a viable option due to the cornea’s steep curvature.
If the rest of the eye, including the retina and optic nerve, remains healthy, the cornea can be successfully replaced through transplantation. Corneal transplants are among the most effective organ transplant procedures. The outcome largely depends on the extent and nature of damage caused by disease or injury.
Cornea Transplant Procedure:
Layered Corneal Transplantation:
With advancements in medical techniques, specific layers of the cornea, such as the epithelium, stroma, or inner cell lining (endothelium), can be selectively transplanted as needed.
- In most cases, corneal replacement surgery is performed as an outpatient or day care procedure using local anesthesia.
- The eyelids are thoroughly cleansed and covered with a sterile plastic drape.
- The surgery is conducted under a microscope, using a specialized instrument called a ‘trephine’ to remove the central part of the damaged cornea.
- A precisely sized button-shaped tissue is extracted from the donor cornea.
- This donor tissue is carefully stitched into place on the patient’s eye using ultra-fine nylon sutures.
- A protective patch and shield are applied to safeguard the eye from external contact.
Corneal transplants for keratoconus can be performed through two main techniques: Penetrating Keratoplasty (full-thickness corneal transplant) and Deep Anterior Lamellar Keratoplasty (DALK).
2. DSAEK
DSAEK: A Modern Corneal Transplant Technique for Faster Recovery and Improved Vision
DSAEK is an advanced corneal transplant procedure that offers a shorter recovery period and enhanced vision post-surgery.
Who Requires DSAEK?
A DSAEK corneal transplant is recommended for individuals experiencing:
- Fuchs’ dystrophy or trauma-related damage to the eye area
- Endothelial dysfunction caused by previous eye surgeries or specific eye diseases
- Progressive endothelial damage due to disease or injury, which can ultimately result in vision loss
This procedure can significantly aid in restoring vision and improving eye health.
DSAEK Procedure
Before the Surgery:
Prior to the procedure, the surgeon may require medical tests such as an EKG, chest X-rays, and blood tests. They will also review any ongoing medications to ensure patient safety.
During the Surgery:
- The procedure is performed under local anesthesia, which numbs the eye and prevents movement during surgery.
- A small incision is made in the cornea to access its inner layers.
- The damaged section of the cornea is carefully removed and replaced with a healthy donor corneal layer.
- The surgery is typically completed within an hour, and the donor cornea settles into position without the need for stitches or additional incisions in the outer cornea.
- As a result, patients benefit from a faster recovery and a reduced risk of complications.
3. DALK
Understanding Corneal Transplantation and the Benefits of DALK
Corneal transplantation is a procedure that can help restore functional vision in an eye affected by corneal damage. However, as with any surgical intervention, the potential risks must be carefully considered against the severity of the patient’s condition.
What is DALK?
Deep Anterior Lamellar Keratoplasty (DALK) is a partial-thickness corneal graft that preserves the innermost layers of the cornea, specifically the endothelium and Descemet’s membrane. The primary goal of this technique is to retain the patient’s endothelium, which plays a crucial role in maintaining corneal clarity by regulating fluid levels.
Advantages of DALK
DALK offers several benefits, including:
- Lower risk of postoperative complications
- Reduced chances of graft rejection
- Shorter duration of topical steroid therapy
The DALK Procedure
This procedure requires a high level of surgical expertise. The steps include:
- The cornea is carefully cut to approximately 95% thickness, and the damaged outer layers are removed.
- The donor corneal button is prepared by eliminating its Descemet’s membrane and endothelium.
- The donor graft is then meticulously sutured to the patient’s cornea.
Importance of Early Diagnosis and Treatment
Detecting corneal conditions at the early stage can make a significant difference in treatment outcomes. Regular eye examinations are essential to monitor corneal health and detect any abnormalities. Patients experiencing symptoms such as blurred vision, sensitivity to light, persistent redness, or pain should seek immediate consultation with an eye specialist.
