Deep Anterior Lamellar Keratoplasty (DALK)

Deep Anterior Lamellar Keratoplasty (DALK) removes the entire anterior cornea up to the very thin Descemet’s membrane.  It is a newer technique that maintains the posterior corneal integrity, minimizing endothelial rejection.  The surgical technique is slightly more difficult and delicate.  Post-operative appearance is very similar to a penetrating keratoplasty, as both surgeries require similar suturing techniques. 

The anterior diseased central cornea is carefully dissected away from the patient's normal posterior cornea (Descement's membrane), taking care not to perforate the membrane.  The new donor cornea graft is measured and cut with a trephine.  The Descemet's membrane is removed, the graft is placed over the patient's native Descemet's membrane, and sutured in place with approximately 16-20 stitches.  The surgery usually takes 60 minutes. The eye is numb completely during the surgery and patients are sedated ("twilight sleep") during the procedure. A patch and shield is placed on the eye and remains in place until the next day follow-up examination in the office.  Eye drops are used to prevent infection and rejection.  The transplant can take several months to heal and stabilize.  Sutures may be selectively removed after a few months.  All the sutures do not have to be removed.  Dr. Koreishi examines and decides which sutures should be removed to allow the best healing, corneal contour, and vision outcome.  Most patients will need glasses, contacts, or rigid gas permeable contacts after a transplant.  Vision recovery can take up to 6-9 months.
 
Specific post-op instructions will be given at the time of surgical counseling and after surgery.  Risks are inherent to any surgical procedure.  Detailed risks, benefits and alternatives will be discussed thoroughly between each patient and the doctor at the time of consultation.


Each patient's eye is different. The description above may not apply to every individual situation. Your doctor will perform a full evaluation and discuss her findings thoroughly. A treatment regimen will be planned and re-evaluated throughout follow-up visits. Please contact your doctor if you feel you have dry eyes or if you have any concerns or questions regarding your ocular health. 



As cornea specialists in DFW, Dallas-Fort Worth, Dr. Koreishi and Dr. Ple-plakon strive to provide the best cornea care, availability, and patient education.
