Summary
One-piece mushroom keratoplasty effectively treats corneal perforations and deep stromal opacities. This surgical technique ensures high rates of transparent corneal engraftment with good visual outcomes.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Regenerative Medicine
Background:
- Corneal perforations and deep stromal opacities pose significant challenges in vision restoration.
- Descemet's membrane involvement complicates standard surgical interventions.
- Innovative keratoplasty techniques are crucial for improving patient outcomes.
Purpose of the Study:
- To clinically evaluate the efficacy of one-piece mushroom-shaped keratoplasty.
- To assess the surgical outcomes for patients with severe corneal damage.
Main Methods:
- A cohort of 10 patients with corneal perforations and deep stromal opacities underwent one-piece mushroom keratoplasty.
- Hypothermically preserved donor corneas were utilized for transplantation.
- A specialized surgical technique involving a Moria vacuum trephine with differential blade diameters was employed.
Main Results:
- Successful transparent cornea engraftment was achieved in all 10 patients.
- The average best-corrected visual acuity was 0.55 ± 0.22.
- Mean corneal astigmatism was 3.35 ± 1.73 diopters, with refractive spherical components ranging from -4.25 to +2.75 D.
Conclusions:
- One-piece mushroom keratoplasty is an effective treatment for corneal perforations and deep stromal opacities involving Descemet's membrane.
- The technique ensures a high success rate for transparent corneal engraftment.
- The specialized trephine use minimizes the risk of graft decentration, enhancing surgical precision.
