Summary
A handheld slit beam aids surgeons in identifying graft orientation during Descemet membrane endothelial keratoplasty (DMEK) and confirming big bubble formation in deep anterior lamellar keratoplasty (DALK), improving outcomes.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Corneal Transplantation
Background:
- Descemet membrane endothelial keratoplasty (DMEK) and deep anterior lamellar keratoplasty (DALK) are advanced corneal transplantation procedures.
- Accurate graft positioning and confirmation of surgical steps are crucial for successful outcomes.
Purpose of the Study:
- To detail methods for utilizing a handheld slit beam.
- To enhance visualization of detached Descemet membrane during DMEK and DALK procedures.
Main Methods:
- Employed the Eidolon model 510L handheld slit lamp.
- Used the slit beam to assess graft orientation in DMEK before unrolling.
- Applied the technique to identify big bubble formation in DALK.
Main Results:
- The slit beam allows DMEK surgeons to determine graft endothelium side for correct placement or air injection.
- In DALK, the technique verifies big bubble presence through stromal opacity post-air injection.
Conclusions:
- The described slit beam techniques offer valuable assistance to surgeons performing lamellar keratoplasty.
- Implementation of these methods is expected to lead to improved patient results in corneal transplantation.

Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...
01:22Overview of Microscopy Techniques
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...
