Clinical Application of a Novel Corneal Biomechanical Device in Refractive Surgery
A Study of the Clinical Applications of a Novel Corneal Biomechanical Device in Refractive Surgery
This study aims to evaluate the accuracy of corneal Young's modulus measurements (E_CID and E_Steady-State) obtained using a steady-state corneal biomechanical measurement device in patients scheduled to undergo refractive surgery and to explore their potential applications in assisting refractive surgical procedures.

Participants wear negative-pressure goggles, and a pressure test is performed to ensure an adequate seal. They then position their chin on the chinrest and fixate on a target while the operator aligns the imaging system with the cornea. The device applies controlled negative pressure and captures corneal deformation images using a Scheimpflug camera, with a coaxial imaging system assisting in alignment and monitoring eye movements. Following data acquisition, the software analyzes corneal biomechanical parameters and generates an assessment report. |
