Summary
This study compared oscillating and rotating lamellar keratome techniques for corneal dissection. The rotating keratome showed potential for smoother surfaces with optimized settings, offering improved options for lamellar keratoplasty.
Area of Science:
- Ophthalmology
- Biomedical Engineering
- Materials Science
Context:
- Lamellar keratoplasty techniques are evolving.
- Accurate dissection of corneal tissue is crucial for surgical outcomes.
- Surface quality impacts graft integration and visual recovery.
Purpose:
- To compare the surface characteristics of two lamellar corneal dissection techniques.
- To evaluate the impact of cutting parameters on surface quality.
- To discuss the clinical applicability of different dissection methods.
Summary:
- Porcine corneas were dissected using oscillating and rotating lamellar keratomes.
- Scanning Electron Microscopy (SEM) revealed smoother surfaces with oscillating blades, while rotating keratomes produced wavy textures.
- Optimizing rotation speed and feed rate improved the rotating keratome's surface quality.
Impact:
- Findings provide insights into optimizing lamellar keratoplasty techniques.
- Understanding surface morphology can guide the selection of dissection methods for better clinical results.
- This research contributes to the development of advanced corneal surgical tools.
