Description

The 67B ANIRIDIA IOL, developed by Morcher, is a specialized intraocular lens designed to address the unique challenges faced by patients with aniridia, whether congenital or acquired. This condition, characterized by the partial or complete absence of the iris, often results in significant visual impairment, increased glare, and light sensitivity. The 67B ANIRIDIA IOL serves as both a functional and cosmetic solution, aiming to restore visual function and improve the aesthetic appearance of the eye.

Key Features

• Artificial Iris Design: The lens features an artificial iris diaphragm, making it suitable for complex anterior segment reconstruction. It is particularly beneficial for patients with large iris defects and those with a history of multiple ocular surgeries.

• Material Options: Constructed from custom silicone or black PMMA, the lens offers durability and adaptability. The total diameter options of 12.5 mm or 13.5 mm, along with varying diaphragm sizes, provide tailored solutions for individual patient needs.

• Optic Design: Available in Sundmacher and Masket designs, the lens includes biconvex optics with diameters of 3.0 mm and 4.0 mm, respectively. Haptic angulation varies between designs, influencing the required incision size for implantation.

Surgical Integration

The 67B ANIRIDIA IOL can be integrated with other surgical procedures such as penetrating keratoplasty, anterior vitrectomy, or tube shunt revision. It can be sutured to the sclera using techniques like knotless Z-sutures or CV-8 Gore-Tex sutures, providing flexibility in placement within the ciliary sulcus or capsular bag.

Clinical Outcomes

Patients receiving the 67B ANIRIDIA IOL often experience significant improvements in visual function, reduction in glare, and enhanced light sensitivity management. Aesthetic outcomes are also notably positive, with effective centering of the artificial iris in most cases.

Potential Complications

While the device offers substantial benefits, potential postoperative complications include inflammation, intraocular pressure elevation, secondary glaucoma, and cystoid macular edema. Careful surgical handling is advised, particularly due to the brittleness at the haptic-diaphragm junction in black PMMA models.

Certification and History

Clinically tested since 1991 and CE certified since 1994, the 67B ANIRIDIA IOL represents a well-established option for ophthalmic surgeons seeking to address the complex needs of patients with significant iris defects. Customization options, including diopter ranges and design specifications, further enhance its applicability across diverse clinical scenarios.
