Description

The 67G ANIRIDIA IOL by Morcher is a specialized intraocular lens designed to address the unique needs of patients with partial or total aniridia. This condition, whether congenital or resulting from trauma, presents significant challenges in visual clarity and glare reduction. The lens serves as an effective solution for those undergoing aphakia or cataract surgery where iris reconstruction is necessary.

Key Features

• Diaphragm Design: The lens features a black diaphragm made from poly(ethyl methacrylate) (PEMA), providing an adjustable size ranging from 3.0 mm to 10.0 mm. This design helps mimic the natural function of the iris, reducing glare and enhancing visual comfort.

• Optic Specifications: At the core of the lens is a clear poly(methyl methacrylate) (PMMA) optic with a central transparent zone of 3.0 mm. The central pupillary aperture measures 5.0 mm, allowing precise light transmission for improved visual outcomes.

• UV Protection: Equipped with a UV filter, the lens offers essential protection against UV light, safeguarding the eye without additional blue light control.

Technical Specifications

• Diameter: The lens has an overall diameter of 12.5 mm, suitable for implantation in the capsular bag with options for scleral fixation.

• Haptics: Constructed from PMMA with 0° angulation, the biconvex haptics ensure stable positioning within the eye.

• Refractive Index: With a refractive index of 1.49, the lens is available in a diopter range of 10.0 to 30.0 D in 0.5 D increments, with additional ranges available upon request.

• Incision Size: Typically requiring an incision size greater than 10.0 mm, the lens is not preloaded and may be requested without the optic if needed.

Surgical Considerations

• Fixation: Scleral fixation is recommended using 9-0 double-armed Prolene sutures with spatula needles. The lens constants include an A constant of 119.6 and ACD constants of 5.37 and 5.90 when sclera sutured.

Benefits

The 67G ANIRIDIA IOL is crafted to enhance visual acuity and reduce glare disability in patients with iris deficiency. Its biocompatible materials and thoughtful design make it a reliable choice for ophthalmic surgeons seeking to improve patient outcomes in complex cases of aniridia.
