Assessing biomechanical corrections: A comparison between Corvis ST and ICare tonometer for intraocular pressure measurement

Results in Optics, 2023
This study aims to compare the accuracy of IOP measurements in pediatric patients using two different tonometers: ICare PRO and Corvis ST (CST). However, the choice of tonometers may vary between screening centers, depending on patient suitability.

Application of the Brillouin Optical Scanning System in the Regional Corneal Biomechanical Evaluation of Keratoconus and Its Correlation with Corvis ST Parameters. [PDF]

Bioengineering (Basel)
(1) Background: The early diagnosis of keratoconus is critical for prognosis. Traditional methods like ORA and Corvis ST measure overall corneal biomechanics but lack regional specificity and are affected by intraocular pressure.
