Description

The 68 ANIRIDIA IOL is a specialized intraocular device designed for individuals with aniridia and aphakia, providing both functional and cosmetic benefits. This implant serves as an artificial iris and lens, addressing visual challenges such as photophobia and glare while restoring the appearance of the iris.

Key Features

• Biconvex Monofocal Lens: The lens features a biconvex, monofocal, refractive design with a spherical optic, enhancing visual clarity.
• Customizable Size: The diaphragm size ranges from 4.5 mm to 10 mm, with overall dimensions customizable between 9.0 mm and 12.5 mm in 0.5 mm increments.
• Iris Mimicry: The peripheral region is colored to mimic the natural iris, available in various pigmentation options for seamless integration.

Implantation Versatility

The 68 ANIRIDIA IOL offers versatile implantation options, suitable for placement in the capsular bag, sulcus, or via scleral fixation. It supports advanced surgical techniques, including suture fixation and sutureless methods like the Yamane technique. The device can be folded for insertion through small incisions or sutured directly to the sclera.

Material Composition

• Optic Material: Constructed from black PEMA and PMMA, providing durability and stability.
• Haptics Material: Made from PMMA with zero-degree angulation, ensuring secure positioning.
• Alternative Material: The artificial iris component may use highly biocompatible flexible silicone.

Optical Properties

• Refractive Index: 1.49
• A Constant: 119.6 for scleral sutured cases
• ACD Constants: 5.37 and 5.90 for scleral sutured cases

Light Protection

The device includes UV-light protection with tinted options to reduce photophobia. It does not offer blue light control and does not correct astigmatism.

Clinical Outcomes

Clinical results indicate a significant reduction in light sensitivity and glare, with high patient satisfaction regarding cosmetic outcomes. The implant demonstrates long-term structural stability, maintaining position without migration, tilt, or corneal contact.

Considerations

Potential complications include corneal edema and decreased endothelial cell density, particularly in eyes with prior trauma or multiple surgeries. Long-term monitoring is recommended. The device is not intended for use in phakic eyes due to the risk of cataract formation.

Special Design Notes

The 68 ANIRIDIA IOL is engineered to address challenges such as zonular weakness and lens capsule fragility in aniridia. It can be trimmed to fit the specific needs of the patient’s eye, offering a tailored solution for complex ocular conditions.
