Abstract

We demonstrate micro-scale vibrations of the porcine corneas as the result of the stimulation of the eye with air puff. Phase-resolved swept-source optical coherence tomography instrument was used to examine the post-air-puff reaction of the corneas. The impact of the intraocular pressure on vibration amplitude and frequency was examined. The results showed characteristic modes of vibration that will be correlated with the intraocular pressure level. The presented approach represents the next step towards understanding the eye dynamics due to air-puff-based mechanical stimulation.
