A corneal mold to restore normal corneal dimensions

Area of Science:

• Ophthalmology
• Biomaterials Science
• Surgical Innovation

Background:

• Post-mortem corneal tissue is often edematous and lacks normal thickness and curvature.
• Existing methods for processing corneal tissue for research are limited.
• Standardized corneal buttons are crucial for reproducible experimental refractive surgery.

Purpose of the Study:

• To describe a novel corneal mold for processing post-mortem corneal tissue.
• To produce a uniform corneal button with normal thickness and curvature from edematous tissue.
• To facilitate the use of processed corneal tissue in experimental refractive surgery.

Main Methods:

• Development of a specialized corneal mold.
• Processing of edematous, post-mortem corneal buttons using the mold.
• Evaluation of the thickness and curvature of the processed corneal buttons.

Main Results:

• The corneal mold successfully produced a corneal button of normal thickness.
• The processed corneal button exhibited normal curvature.
• The uniform tissue is suitable for experimental refractive surgery.

Conclusions:

• A novel corneal mold effectively processes edematous, post-mortem corneal buttons.
• The resulting uniform corneal buttons are viable for experimental refractive surgery research.
• This technique enhances the utility of post-mortem corneal tissue for scientific investigation.
