Characterization of the Corneal Biomechanics of Patients Treated by Corneal Lenticule Extraction for Advanced Refractive Correction (CLEAR) to Correct Myopia

NCT04817592 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 100

No results posted yet for this study

Summary

This study aims to perform biomechanical tests on extracted CLEAR lenticles that are routinely discarded after surgery. The investigators also aim to perform Brillouin microscopy to get an in-vivo assessment of the patient's cornea preoperatively and to correlate this data with the postoperative characterization of the extracted corneal lenticule. The characterization will be done with established biomechanical and morphologic tests.
