What
Deep anterior lamellar keratoplasty replaces the damaged anterior stroma while preserving the recipient's Descemet's membrane and endothelium. A common practice is to inject gas into the corneal stroma to form a separation, or to gradually cut and remove the diseased tissue in layers, and then suture and fix the donor anterior stroma with the endothelium removed. Postoperatively, corneal transparency, corneal shape, and intraocular pressure are monitored, with the goal of improving optical quality and reducing endothelial-related risks. The above is general health information and not medical advice; specific information is subject to specialist assessment and hospital protocols.
How
- Inject gas into the corneal stroma to form a separation.
- Gradually cut and remove the diseased tissue in layers.
- Suture and fix the donor anterior stroma with the endothelium removed.
- Postoperatively, monitor corneal transparency and intraocular pressure.
Recovery
Postoperative visual recovery is staged, and regular eye drops and scheduled follow-up visits are required in the early stage; avoid rubbing the eyes and collisions, and postpone water activities such as washing the face and swimming. The suture retention time and removal strategy are determined by follow-up, and may require multiple adjustments. Whether or not to fly is subject to the doctor's assessment, and please bring medical records and a list of medications when going out. Seek medical attention promptly if symptoms worsen or vision changes suddenly.
- Administer eye drops regularly and follow-up visits as scheduled.

FAQ
Will rejection occur?
DALK preserves the endothelium, and the immune-related risks and manifestations are different from full-thickness transplantation; seek medical attention as soon as possible if redness, pain, or vision loss occurs.
What if DALK is not suitable?
Penetrating transplantation may be performed, or contact lenses, cross-linking, and other protocols may be used, and the final path is subject to specialist assessment.
Will the surgery leave scars?
The corneal incision needs to be sutured, and fine suture marks may remain on the surface; the optical quality depends on healing and suture adjustment.
Can I pass security or have an MRI?
Sutures and transplanted tissue generally do not affect security checks or MRI; it is recommended to bring surgical records and a doctor's certificate when going out.
Where does the donor cornea come from?
Usually donated corneas are provided by compliant eye banks and meet screening and quality standards; acquisition and use are subject to local laws and procedures.
Can I wear contact lenses after surgery?
It depends on the assessment of corneal shape and suture stability, and some people can wear rigid or scleral lenses to optimize vision.
Do I need to take medication for a long time?
Antibiotic and steroid eye drops are commonly used in the early stage, and then gradually reduced; the course and frequency are adjusted by the doctor during follow-up.
How long will it take to return to work/study?
The recovery progress varies greatly, and near vision and driving need to be confirmed by follow-up; it is recommended to reserve sufficient rest time.
