ESPI and PulsESPI Applied to Ophthalmology Using Modified Twymann-Green Interferometer

Abstract:
Perhaps for the first time ever, application of Pulsed Electronic Speckle Pattern Interferometry (PulsESPI) technique to an animal (bovine) cornea for the investigation of its dynamic behavior to localized stresses is being presented. For the target of obtaining optimal results from laser ophthalmic surgery for the correction of cornea, it has already been observed that more attention is required on the adjustment of the necessary ablative laser power, while taking into account the otherwise neglected corneal elasticity as a parameter. It is being proposed that this need can be fulfilled by analyzing through this technique the behaviour of cornea under application of variable dynamic stresses. By addition of elasticity to the related cornea mathematical model, corneal healing evolution can also be forecasted for follow-up and for perfecting the correction during the post-op period. The tests were complemented by an in vitro measurement of the surface contour of the same cornea using a Twymann-Green Interferometer.
