ABSTRACT

PURPOSE:

To describe a new technique for preparing corneal allogenic ring segments (CAIRSs) using femtosecond laser technology.

SETTING:

Hospital Foundation Adolphe de Rothschild-Noémie de Rothschild institute, Paris, France.

DESIGN:

Preclinical study conducted on human corneal grafts.

METHODS:

The corneal grafts were mounted on an artificial chamber pressurizer (ACP) with preset constant pressure, and the FSL was used to create a circular annulus with specific dimensions. The resulting CAIRSs were analyzed for their thickness and width after air drying.

RESULTS:

A total of 25 CAIRSs were prepared using the FSL. The mean width and thickness of the CAIRSs were 803 ± 77 µm and 83 ± 16 µm, respectively. Statistical analysis revealed no significant differences in width among the various quadrants of each CAIRS or between different CAIRSs. Significantly thicker CAIRSs were obtained with a higher ACP pressure.

CONCLUSIONS:

The technique of CAIRS preparation using FSL technology and controlled artificial anterior chamber pressure demonstrated reproducibility and precision. This approach holds the potential for customizing and personalizing CAIRSs based on individual corneal characteristics.
