Long-term complications of cosmetic iris implants.

Background: Additive cosmetic implants (NewColorIris, Kahn Medical Devices, Panama City, Panama) are placed in the anterior chamber, in order to externally change iris color. There is a lack of robust clinical long-term prospective studies regarding the safety of these devices, as they have been related to the early-onset presentation of corneal decompensation, elevated intraocular pressure (IOP), uveitis and hyphema. However, in this case report some mild complications started to manifest unexpectedly late: 15 years after an uneventful procedure.
