Irises Unlimited produces over 800 unique sample iris buttons which represent every possible human eye color and structure combination. In addition, parts of any iris on the board may be chosen to make a custom iris instruction that allows an ocularist to make an eye more efficiently and higher quality with precise color and structure replication.
Each iris has a dash number which corresponds to its value in steps of 5 points of lightness.
In order to make a custom iris, the diameter of the iris may be calculated using an object with a known diameter, such as a coin for example that is held on the same plane as the patient’s iris.
For example, a US dime is 17.91 mm in diameter which would represent the variable b in this equation.
In your iris instruction, components of any iris can be used with another, such as the collarette color from B4371-5 or the limbus color from Br2243-7. In addition, slight color adjustments, lightness, and fine structure may also be specified, preferably in conjunction with a target iris color.
This video shows how to turn down your iris button and how to achieve a soft or sharp limbal blend.
