Henriquez MA, et al. - In this prospective cohort study, authors estimated 30 healthy eyes and 31 keratoconus (KC) eyes between January 2017 and July 2017 to study the result of eye rubbing in KC vs healthy eyes on Scheimpflug imaging parameters and corneal biomechanics. The mean change in steeper anterior keratometry, posterior astigmatism, anterior chamber volume, flattest posterior keratometry, and Goldman correlated intraocular pressure (IOPG) after eye rubbing in the KC group was -0.03±0.32 D, 0.14±0.50 D, -5.09±8.45 mm3, 0.03±0.06 mm, and -1.61±1.41 mmHg, respectively. But, in the healthy group, the immediate mean change was 0.07±0.15 Diopters (D), -0.01±0.08 D, 0.03±7.06 mm3, -0.001±0.04 mm, and -1.21±1.99 mmHg, respectively. They noticed statistically significant differences between pre- and post-eye-rubbing values of posterior astigmatism, anterior chamber volume, and IOPG in the KC group but not in the healthy group.
