Area of Science:

Biomechanical modeling
Ophthalmic surgery simulation

Background:

Radial keratotomy (RK) is a refractive surgical procedure.
Understanding corneal biomechanics post-RK is crucial for predicting outcomes.

Purpose of the Study:

To develop a computational model for predicting eyeball displacements and curvatures after RK.
To analyze corneal behavior and incision characteristics following the procedure.

Main Methods:

A closed shell eyeball model was created, treating the cornea and sclera as connected ellipsoidal caps.
The model assumes macroscopic homogeneity and isotropy of corneal and scleral tissues.
A procedure for calculating principal curvature and a FORTRAN program for small displacement analysis were developed.

Main Results:

Related Experiment Videos

The model quantitatively predicts displacements and curvatures with fair accuracy.
Qualitative corneal behaviors observed include V-shaped incision opening and consistent radial displacements.
In-plane displacement was found to be significantly smaller than radial displacement.

Conclusions:

The developed closed shell eyeball model effectively simulates post-RK corneal biomechanics.
The model provides insights into the qualitative changes in corneal shape and displacement after radial keratotomy.
This computational approach aids in understanding and predicting surgical outcomes in refractive surgery.
