New forceps and cutting block for donor corneas

Area of Science:

• Ophthalmology
• Surgical Instrumentation
• Corneal Transplantation

Background:

• Accurate preparation of donor corneal buttons is critical for successful corneal transplantation.
• Current methods for handling and cutting corneal tissue can be challenging, potentially impacting graft quality.

Purpose of the Study:

• To introduce novel surgical instruments designed to enhance the precision and ease of preparing donor corneal buttons.
• To address limitations in existing tools for corneal tissue manipulation.

Main Methods:

• Development of 12-mm media forceps specifically for grasping corneal tissue.
• Creation of a variable curved Teflon block featuring centering targets for precise cutting and alignment.

Main Results:

• The new instruments facilitate improved handling and cutting of donor corneal buttons.
• The design aims to increase accuracy and reproducibility in corneal graft preparation.

Conclusions:

• The developed instruments offer a potential advancement in the surgical preparation of corneal grafts.
• These tools may contribute to better outcomes in corneal transplantation procedures.
