Corneal grafts restore vision when scarring suddenly blurs sight during family moments, turning clarity hazy. These transplants treat keratoconus and Fuchs dystrophy common in the UAE. Modern methods shorten recovery while enhancing outcomes. Discover optimal graft types for specific pathologies.
Corneal Grafts: Penetrating Keratoplasty (PK) Technique
Penetrating Keratoplasty replaces the full-thickness cornea with donor tissue using precise trephination. The traditional full-thickness approach suits advanced disease. Key characteristics:
- Full replacement: Entire cornea exchanged (epithelium to endothelium).
- Indications: Keratoconus stage IV, leukoma, trauma scars. (watch this video)
- Suture time: 12-18 months, interrupted sutures.
- Visual recovery: 12-24 months for optimal refraction.
PK provides structural stability for severe cases.
DSAEK Technique: Partial-Thickness Endothelial Graft
DSAEK (Descemet Stripping Automated Endothelial Keratoplasty) transplants only the endothelium and Descemet membrane through a small incision. Minimally invasive posterior approach preserves stromal strength. Procedure highlights:
- Donor size: 8mm disc injected via 3mm incision.
- Attachment method: Air tamponade unfolds the graft.
- Indications: Fuchs dystrophy, pseudophakic bullous keratopathy.
- Recovery: Vision is functional within 1-2 weeks.
DSAEK excels in endothelial failure.
DALK Technique: Anterior Lamellar Graft
Deep Anterior Lamellar Keratoplasty replaces the stroma while preserving the patient’s endothelium. Selective stromal removal maintains natural pump function. Technical features:
- Big bubble technique: Air dissects the pre-Descemet plane.
- Endothelium spared: 95% patient cells retained.
- Indications: Keratoconus stage I-III, stromal scars.
- Suture burden: Reduced rejection risk (20% vs PK 40%).
DALK balances preservation and correction.
Corneal Grafts Comparison: PK vs DALK vs DSAEK
Each technique targets specific corneal layers with distinct outcomes. UAE surgeons select based on the pathology depth.
| Aspect | PK | DALK | DSAEK |
| Layers replaced | Full thickness | Stroma only | Endothelium |
| Suture time | 12-18 months | 6-12 months | 0-6 months |
| Rejection rate | 20-40% | 10-20% | 10-15% |
| Recovery | 12 months | 6 months | 1 month |

Factors in Choosing Corneal Grafts: Patient Pathology Match
Diagnosis determines graft selection. Comprehensive UAE corneal evaluation guides optimal technique.
Selection criteria:
- PK: Advanced keratoconus, full-thickness scars, trauma.
- DALK: Stromal pathology with healthy endothelium.
- DSAEK: Endothelial failure, bullous keratopathy.
- Contraindications: Active infection, poor tear film, unrealistic expectations.

Frequently Asked Questions
Which graft has the fastest recovery?
DSAEK typically 1-2 week functional vision.
Does DALK preserve my own endothelium?
Yes, retains 95% patient endothelial cells.
Long wear sutures after PK?
12-18 months with selective removal.
Can keratoconus use DSAEK?
No, DSAEK treats endothelial disease only.
Which graft rejects the least?
DALK shows 10-20% rejection versus PK 40%.
