Prosthetic iris devices

Long-term results after artificial iris implantation in patients with aniridia

“…Most cases of aniridia occur after severe ocular trauma, less common causes are congenital, ICE-syndrome, or an iatrogenic iris defect. While small defects can be repaired with specific suture techniques [1], more complex cases require an iris prosthesis [2,3]. Due to limited flexibility of the iris tissue, better iris implants have evolved over the last decade with soft and foldable material for easy and minimal invasive implantation and with enough structural stability for suturing [4].…”

Elevated Intraocular Pressure and Endothelial Cell Loss Following Iris Color Change

“…1 However, a newer trend has been the implantation of these devices for purely cosmetic purposes. Figure 1 features a PID called NewColorIris, which has been associated with serious postimplant complications in several published reports.…”

Surgical technique for explantation of cosmetic anterior chamber iris implants

“…4 With a poor fit, the increased mobility of the implant may result in mechanical trauma to the corneal endothelium and angle structures. 1 Increased IOP may also result from the semicircular flaps on the implant directly impinging on the trabecular meshwork. Pigment dispersion and PAS are among other potentiating factors for increased IOP.…”

“…The implants are used to treat congenital and acquired aniridia, ocular albinism, iris coloboma, and other iris defects. 1 In 2004, a silicone anterior chamber, anglesupported implant, the Newcoloriris (Kahn Medical Implants), was described for treatment of oculocutaneous albinism. A It has subsequently been marketed in Panama for cosmetic alteration of the iris color.…”
