DALK (Deep Anterior Lamellar Keratoplasty)
DALK (Deep Anterior Lamellar Keratoplasty)
DALK surgery at The Sight Centre offers an advanced corneal transplant solution for those with conditions affecting the front and middle layers of the cornea. This innovative procedure can significantly improve vision while preserving your eye’s innermost corneal layer.
By selectively replacing the damaged anterior corneal tissue with healthy donor tissue, we can restore clarity to the eye’s surface while maintaining the integrity of your own endothelial cells.
Our experienced team of consultant ophthalmologists combines surgical precision with cutting-edge techniques to deliver this sight-saving procedure safely and effectively.
Benefits of DALK
- Preserves the patient’s own endothelial cells
- Lower risk of endothelial rejection compared to full-thickness transplants
- Stronger wound healing and structural integrity
- Suitable for conditions like keratoconus and corneal scarring
- Faster visual recovery for many patients
- Potential for better long-term graft survival
What is DALK?
Deep Anterior Lamellar Keratoplasty (DALK) is a partial-thickness corneal transplant procedure that replaces the front and middle layers of the cornea (epithelium and stroma) while leaving the innermost layer (Descemet’s membrane and endothelium) intact.
The procedure involves carefully separating the layers of the cornea and removing the damaged anterior portions. Healthy donor tissue is then grafted onto the remaining posterior corneal layer.
This technique is particularly beneficial for conditions that affect the front and middle corneal layers but spare the endothelium, such as keratoconus, corneal scarring, and certain corneal dystrophies.
DALK is typically performed under local anaesthesia with sedation and can take 1-2 hours to complete.
BOOK APPOINTMENTWhy Choose DALK?
Discover the vision-enhancing benefits of DALK. This advanced corneal transplant technique can help improve your vision while preserving more of your own corneal tissue.
Reduced Rejection Risk
By preserving your own endothelial cells, DALK lowers the risk of endothelial rejection, a common complication in full-thickness corneal transplants.
Stronger Wound Healing
The interface between your own posterior cornea and the donor tissue allows for stronger wound healing and better structural integrity.
Preserves Natural Inner Layer
Keeping your own endothelial cells intact can lead to better long-term outcomes and graft survival.
Suitable for Various Conditions
DALK is an excellent option for conditions like keratoconus, corneal scarring, and certain corneal dystrophies that affect the anterior cornea.
Faster Visual Recovery
Many patients experience faster visual recovery with DALK compared to full-thickness transplants.
Tailored Treatment
The procedure can be customised based on the depth of your corneal damage, ensuring the best possible outcome.
Long-lasting Results
With proper care, a DALK transplant can provide long-term vision improvement and corneal stability.
Your Treatment Journey
At The Sight Centre, we understand that any eye surgery can be concerning. That’s why our team of expert ophthalmologists is dedicated to guiding you through every step of the DALK process and ensuring your comfort and safety.
Preparation and Anesthesia
Before your surgery, we’ll administer local anaesthesia and sedation to ensure your comfort throughout the procedure. Your eye will be thoroughly cleaned and prepared for surgery.
Surgical Procedure
Your surgeon will carefully separate the layers of your cornea and remove the damaged anterior portions. The healthy donor tissue will then be precisely positioned and secured in place. The exact technique may vary depending on your specific condition and corneal anatomy.
Post-Operative Care
Immediately after your surgery, we’ll provide detailed post-operative care instructions. These may include using prescribed eye drops, wearing a protective eye shield, and attending regular follow-up appointments. Most patients can go home the same day, but you’ll need someone to drive you.
DALK FAQs
How long does it take to recover from DALK?
Initial recovery takes about 1-2 weeks, but vision continues to improve over several months. Full visual recovery can take 6-12 months.
Will I still need to use anti-rejection medication after DALK?
Yes, you’ll need to use steroid eye drops to prevent rejection, but typically for a shorter duration than with full-thickness transplants. Your ophthalmologist will provide a detailed medication plan.
How does DALK compare to a full-thickness corneal transplant?
DALK preserves your own endothelial cells, which can lead to better long-term outcomes and a lower risk of endothelial rejection. However, it may not be suitable for all corneal conditions.
Will I need glasses or contact lenses after DALK?
Many patients still require glasses or contact lenses after DALK to achieve their best vision. Your prescription may change as your eye heals.
What are the risks associated with DALK?
While generally safe, risks can include infection, graft rejection, and irregular astigmatism. In rare cases, the procedure may need to be converted to a full-thickness transplant during surgery.
How soon can I return to work after DALK?
Most patients can return to office-based work within 2-4 weeks, but this can vary. Your surgeon will provide specific guidelines based on your individual case and healing progress.
