Prosthetic iris preparation method

摘要

A method and system for making digitized iris prints for prosthetic eyes in a consistent, efficient, and cost-effective manner using digitally created and stored irises. A database of known iris colors and characteristics can be stored and associated with unique quantitative identifiers. An ocularist is provided with an array of sample irises containing known iris colors and characteristics matching the iris colors in the database. Each sample iris has unique, scientific, reproducible quantitative markers or indicia. The ocularist can select one sample iris from the array where the iris color and characteristic most closely matches the natural eye. The selected sample iris can be identified by its unique quantitative markers, and vice versa. The identifier can be looked up in the database of known iris colors. Furthermore, by applying the tools of the digital age to an artistic skill and trade that goes back many decades, a new easy-to-reproduce iris with appropriate modification to selected markers for a digitized iris print can be created and used for the new prosthetic eye. Accordingly, maximum success is achieved by maintaining control of technical variables which include, but are not limited to, hue, saturation, brightness, iris dimensions, and effect of clear PMMA encapsulation.

主权项

1. A method for producing a color-matched iris for a prosthetic eye, comprising:
a. providing an array of sample irises, each sample iris comprising:
i. a sample cornea;ii. a digitized iris print encapsulated in the sample cornea; andiii. a plurality of unique indicia associated with the digitized iris print, wherein each sample iris has a plurality of unique characteristics selected from the group consisting of: an iris body color, an inner ring color, a degree of how pronounced the inner ring is, an inner ring dimension, an outer ring color, a degree of how pronounced the outer ring is, and an outer ring dimension, said plurality of characteristics being identifiable by the plurality of unique indicia; b. receiving two or more unique indicia selected by matching at least one sample iris from the array of sample irises with a natural eye of a patient; c. retrieving a digital image associated with the two or more unique indicia; and d. printing the digital image to create a final iris.
