Abstract EN
No study has so far evaluated the impact of coffee drinking on ocular wavefront aberration (OWA) measurements.
This study presents novel findings regarding the OWA of the eye following coffee intake.
We aimed to evaluate the acute changes in pupil size and OWA of the eye after single administration of coffee.
A total of 30 otherwise healthy participants were included in this prospective study.
All subjects drank a cup of coffee containing 57 mg caffeine.
Measurements of pupil size, total coma (TC), total trefoil (TF), total spherical aberration (TSA), and total higher order aberration (HOA) were performed before and at 5 minutes, at 30 minutes, and at 4 hours after coffee drinking using a wavefront aberrometer device (Irx3, Imagine Eyes, Orsay, France).
The mean age of the study population was 20.30 ± 2.74 years.
Pupil size did not show a significant change during the measurements ( p > 0.05 ).
A significant increase was observed in TF and HOA measurements following coffee intake ( p = 0.029 and p = 0.009 , resp.).
Single administration of coffee results in significant increase in TF and total HOAs in healthy subjects without any effect on pupil diameter.
Ultrastructural changes in the cornea following coffee intake might be of relevance to the alterations in ocular aberrations in healthy subjects.
