Thermoelastic analysis of laser iridectomies.
We have attempted to derive the stress-strain-temperature relationships of the iris stroma subject to a restrictive thermal burn from a laser. The corresponding displacement equation embodies the mechanical impulses due to this thermal insult. This thermoelastic analysis of laser iridectomy attempts to describe the mechanism involved in the surgical procedure. It is clear from this study that the flexural behaviour of the iris is principally due to thermal insult and not due to vapour bubbles or redistribution of the aqueous.
