Area of Science:

  • Ophthalmology
  • Biomechanical Engineering

Background:

  • Corneal biomechanics are crucial for eye health and surgical outcomes.
  • Accurate assessment of corneal elasticity in vivo is challenging.

Purpose of the Study:

  • To evaluate the clinical feasibility of in vivo dynamic corneal imaging (DCI).
  • To assess individual elastic properties of normal, abnormal, and post-refractive surgery human corneas.

Main Methods:

  • Utilized DCI with stepwise corneal indentation (50-800 µm) and videotopography.
  • Analyzed corneal topography changes using Zernike polynomials to create a flexing curve.
  • Employed a modified Placido disk-based system for image acquisition.

Main Results:

  • DCI demonstrated reproducible and reversible changes in corneal topography.

  • Flexing curve correlated significantly with indentation depth, intraocular pressure, central corneal thickness, and age.
  • Successfully evaluated keratoconic and post-refractive surgery corneas.

    • Conclusions:

    • DCI is a clinically practical method for assessing in vivo corneal elasticity.
    • Corneal elastic behavior is influenced by multiple clinical parameters.
    • DCI technology may enhance refractive surgery predictability and early disease diagnosis.
