Description

The 68 ANIRIDIA IOL by Morcher is a specialized intraocular lens designed for patients with partial or complete aniridia, often used in conjunction with cataract surgery or anterior segment reconstruction. This lens addresses unique challenges such as zonular weakness and lens capsule fragility, providing a tailored solution for complex ocular conditions.

Key Features

• Monofocal Design: The lens employs a refractive optical principle with a spheric optic, incorporating added spherical aberration (+0.2μ) to enhance visual outcomes. It does not correct astigmatism but offers significant UV-light protection.

• Iris Mimicry: The peripheral colored region of the lens mimics the natural iris, available in various pigmentation options. This feature reduces photophobia and improves cosmetic appearance, with tinted versions available for similar benefits.

Material and Construction

• Optic and Haptics: Constructed from black PEMA and PMMA, the lens is also available as a customizable silicone iris prosthesis, either fiber-free or fiber-reinforced, ensuring biocompatibility and flexibility.

• Design Specifications: The biconvex optic shape includes a pupillary aperture and diaphragm size of 4.5 mm, with an overall customizable diameter ranging from 9.0 to 12.5 mm. The haptic angulation is 0°, providing stability within the eye.

Implantation Details

• Incision and Fixation: Implantation requires a large incision, with options for scleral fixation using 9-0 Prolene. The lens can be folded for insertion through smaller incisions or sutured to the sclera, compatible with most IOL models and capsular tension rings.

• Versatile Placement: It can be implanted in the capsular bag, sulcus, or via scleral fixation, offering versatility to meet various surgical needs.

Optical Properties

• Refractive Index: The lens has a refractive index of 1.49, with specific constants (A constant: 119.6, ACD constant: 5.37 or 5.90) tailored for scleral sutured placement.

Clinical Benefits

Clinical studies highlight significant reductions in light sensitivity and glare, alongside improved cosmetic outcomes, making it particularly beneficial for aniridia patients undergoing cataract extraction. The customizable diameter and pigmentation enhance both functional and aesthetic integration, closely mimicking the natural iris.

This innovative lens design by Morcher offers a comprehensive approach to managing complex ocular conditions, enhancing both visual function and appearance.
