Purpose

To assess the corneal biomechanical properties of healthy individuals at different ages in relation to the corneal thickness and other aspects of the corneal configuration.

Setting

Department of Clinical Sciences/Ophthalmology, Umeå University, Umeå, Sweden.

Methods

This ongoing study involves healthy individuals between 10 and 45 years of age. Best corrected visual acuity, Pentacam Scheimpflug tomography (Oculus, Inc.) and anterior segment optical coherence tomography (AS-OCT; Casia2; Tomey, Inc.) are assessed in both eyes, and the corneal biomechanical properties are measured at 10 points in each cornea using the Brillouin Optical Scanner System (BOSS; Intelon Optics, Inc.).

Results

The results will map the differences in corneal biomechanical properties at different ages, and their relationship to the structural properties of the cornea.

Conclusions

The biomechanical properties of the cornea change with time, and there is no direct relationship between the biomechanics of a cornea and its configuration. This demonstrates the importance of also taking the biomechanical properties of the cornea into account in the planning of, for example, corneal crosslinking in keratoconus or refractive surgery.
