Summary
A novel corneal shovel technique enables atraumatic donor corneal button transfer during transplantation. This method ensures stability, preventing slippage and complications in corneal transplants.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Transplantation Science
Background:
- Corneal transplantation is a common procedure to restore vision.
- Donor corneal button handling during transplantation presents challenges, including potential slippage and trauma.
- Existing methods may lack sufficient stability for precise donor cornea transfer.
Purpose of the Study:
- To develop an atraumatic surgical technique for donor corneal button transfer.
- To enhance the stability and safety of donor cornea manipulation during transplantation.
- To introduce a novel corneal shovel-assisted method for corneal transplantation.
Main Methods:
- A microcorneal shovel is used to lift the donor cornea.
- Drying the epithelial surface with a microsponge creates a seal on the shovel.
- The sealed cornea can be rotated 180 degrees without movement, then transferred to the host eye.
Main Results:
- The technique was successfully applied in 52 corneal transplants.
- No instances of donor corneal button slippage or detachment were observed.
- The method demonstrated effective stabilization and transfer of the donor cornea.
Conclusions:
- The described method offers a reliable and atraumatic approach for donor cornea transfer.
- This surgical technique improves the safety and efficacy of corneal transplantation.
- The corneal shovel method provides a stable platform for precise donor cornea placement.
