Summary
Tectonic grafts are a valuable treatment for corneal thinning and perforations, restoring eye integrity and improving vision. This study evaluated 42 grafts, achieving 85.4% anatomical success and 70.73% visual acuity improvement.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Grafting Techniques
Background:
- Corneal thinning and perforations pose significant risks to vision.
- Tectonic grafts are employed to restore ocular integrity in severe corneal pathologies.
Purpose of the Study:
- To assess the efficacy of tectonic grafts in managing corneal thinning and perforations.
- To evaluate visual outcomes and complications associated with different tectonic graft types.
Main Methods:
- A retrospective analysis of 42 tectonic grafts (full-thickness, mushroom, lamellar) in 41 patients.
- Evaluation of indications, graft types, visual acuity, and postoperative outcomes.
- Assessment of complications including graft melting and synechiae.
Main Results:
- Infection was the leading indication (12 eyes), followed by immunologic causes and trauma.
- Anatomical success was achieved in 85.4% of eyes (35/41).
- Improved visual acuity (6/24 or better) was observed in 70.73% of eyes (29/41), with a mean visual acuity improvement.
Conclusions:
- Tectonic grafting is a successful therapeutic strategy for corneal thinning and perforations.
- It effectively restores ocular integrity and facilitates visual rehabilitation in selected patients.
- Careful patient selection and graft type are crucial for optimal outcomes.
