DALK (Deep Anterior Lamellar Keratoplasty)
Corneal Transplantation

What a great experience! Very reassuring and I am very grateful for the consultation from Dr Musa he was so helpful in helping me make a decision to proceed to having eye correction surgery. I have the upmost confidence in him and the team at the Eye Doctor Clinic, Huddersfield.
Lozza 747I had implants with Dr Musa ten years ago. It was the best thing I've ever done. They are brilliant. My sight both near and distant was very poor but since the op I've had no glasses no lenses and my sight has been super. It remains really good to this day. Thank you Dr Musa. Brilliant consultations and treatment for glaucoma since.
Kay FitbitI can highly recommend the Eye Doctor Clinic, and I am so pleased I went there. Dr Musa, Gemma and Jess are lovely. They are very knowledgeable and were able to answer all my questions. My vision following surgery is great, and not having to wear glasses is fantastic.
Carol PeelDeep Anterior Lamellar Keratoplasty (DALK) is generally considered a last-resort option when vision is severely impaired and the cornea is too thin, scarred, or irregular for other treatments.
DALK (Deep Anterior Lamellar Keratoplasty) Treatment Description
Deep anterior lamellar keratoplasty, commonly known as DALK, is a specialised form of corneal transplant surgery used to treat corneal conditions that affect the front layers of the cornea while preserving the healthy inner layer.
Unlike full-thickness corneal transplantation, DALK replaces only the diseased anterior corneal tissue and leaves the patient's own endothelium intact. This makes it a preferred option for suitable patients, particularly those with keratoconus or anterior corneal disease, because it reduces the risk of endothelial rejection and supports better long-term graft survival.
At the Eye Doctor Clinic, DALK is performed by a consultant corneal surgeon with specialist expertise in lamellar corneal procedures.
How It Works
During DALK, the surgeon removes the front layers of the cornea down to or near the Descemet membrane, which sits just above the endothelium. Donor corneal tissue is then carefully shaped and sutured into place to restore corneal clarity, structure, and curvature.
The procedure is technically demanding and requires specialist surgical skill to achieve consistent results. At the Eye Doctor Clinic, careful surgical planning and technique are central to every procedure.
Is DALK Right for You?
DALK may be recommended when:
- Keratoconus has progressed to a stage where contact lenses or CXL are no longer sufficient
- Corneal scarring is causing significant visual impairment
- Other corneal conditions affecting the anterior layers have not responded to treatment
Conditions treated with DALK include:
- Advanced keratoconus
- Anterior corneal scarring
- Certain corneal dystrophies
- Post-inflammatory corneal scarring
- Corneal thinning disorders with healthy endothelium
Your consultant will assess whether DALK is suitable or whether another corneal procedure is required.
Safety and Success
DALK has an excellent safety profile when performed by an experienced corneal surgeon. The risk of rejection is significantly lower than with full-thickness corneal transplants, and long-term graft survival is high.
At the Eye Doctor Clinic, careful surgical technique and long-term follow-up are central to maintaining graft health and visual outcomes.
Restoring Vision and Quality of Life
By restoring corneal clarity and structure, DALK can significantly improve vision, comfort, and confidence. Many patients regain the ability to read, drive, and return to daily activities with improved visual stability.
For patients with keratoconus, DALK can be a life-changing procedure that preserves vision for the long term.
Why Choose the Eye Doctor Clinic
Every procedure is tailored to protect eye health and maximise visual outcomes.
