Frequently Asked Questions > Immigration > Using Iris Recognition for Immigration Clearance   Question: I had undergone operations owing to eye problems such as serious cataract and glaucoma. Can I use iris recognition for immigration clearance? Answer: Certain serious eye diseases may lead to damage and indistinction of the iris features and other similar conditions that the iris is not recognizable by the iris scanner. In such case, the passenger may not be able to use the “iris automated channel” or conduct self-registration at the “iris automated channel”.   Previous Page
