Cosmetic iris implants - double edge sword.

Iris implants were originally described as an option to treat photophobia and glare associated with aniridia, coloboma, corectopia or any other causes of acquired or congenital iris defects. They are not designed to be used in healthy phakic eyes and not approved by regulatory bodies anywhere in the world for cosmesis. However, widespread publicity and the compulsive need for beautification has popularised the use of these implants illicitly. Implantation into phakic eyes causes mechanical irritation of angle structures leading to chronic inflammation, pigment dispersion, prolonged endothelial cell loss and compression of the trabecular meshwork. The consequences are dire, leading to presentation of such patients with serious complications involving the cornea, angle, and lens. Here we give an extensive review of available literature on cosmetic iris implants and also describe a case with bilateral cosmetic iris implants (New-ColorIris). The patient presented with corneal decompensation, glaucoma, and cataract in both eyes, seven years after the implantation and was successfully managed with explantation of the device followed by a DMEK Triple procedure.
