Regarding eye-iris recognition, biometric evidence points to the view that iris patterns in individuals are randotypic and not shaped by the inherited genome. However, if the psychoplasm (the soul genome with as-yet-unrecognized energetic patterns) does include some inherited physical characteristics that come from the past-life and not the parents (as the reincarnation hypothesis posits), there is a chance that iris patterns could be part of the package. For this reason, I think comparisons should be made between past and present where possible in reincarnation research. This project is collaborating with Adrian Finkelstein, M.D., and colleagues in India to develop a pilot study to make such comparisons.

Technical Issues: Iris matching involves more than just color and size; it is the patterns that count. More than 2000 data points are compared through algorithms to measure the degree of difference. That requires computer software and visual/photo inputs. Some success has been achieved using photographs (not in reincarnation cases) to make reliable matches. See Wikipedia for explanations.
It is for this reason that we suggest that if in evaluating a case the researcher has two good, wide-eyed photos of (past-life) and (present-life), it might be possible for an iris ID expert to calculate a statistical probability that the two photo-sets of eyes were not the same person (the backwards way of demonstrating the likelihood that it is the same person).
If such a comparison of the two photos revealed a very close match, it might reveal an aspect of reincarnation that has not yet been documented. A high-level match would not definitively prove the reincarnation hypothesis, but it would be one more area of corroborating evidence
