Resumen
Purpose: We aimed to assess the impact of drinking water (500 and 1000 mL) on corneal biomechanics
and determine the level of association between changes in intraocular pressure and variations in the
different biomechanical properties of the cornea. Methods: A total of 39 healthy young adults ingested
either 1000 mL (n = 21) or 500 mL (n = 18) of tap water in 5 min. The CorVis ST system was used to assess
corneal biomechanics at baseline and at 15, 30, and 45 min after water ingestion. Results: Water drinking
induced statistically significant changes in the deformation amplitude (P < 0.001, η² = 0.166), highest
concavity time (P = 0.012, η² = 0.093), peak distance (P < 0.001, η² = 0.171), time and velocity of the first
applanation (P < 0.001, η² = 0.288 and P = 0.016, η² = 0.087, respectively), and time and velocity of the second
applanation (P = 0.030, η² = 0.074 and P = 0.001, η² = 0.132, respectively), being independent of the amount
of water ingested (P > 0.05 in all cases). There were significant associations between changes in intraocular
pressure and some parameters of corneal biomechanics. Conclusion: Small variations in whole‑body
hydration status alter different biomechanical properties of the cornea, with these changes being associated
with intraocular pressure levels. These findings indicate that whole‑body hydration status can be considered
for the diagnosis and management of different ocular conditions.
