Description

The Morcher 67G Aniridia IOL is a highly specialized intraocular lens crafted for individuals with partial or total iris deficiency, known as aniridia. This condition may be congenital or result from ocular trauma. Designed to be implanted during aphakia or cataract surgery, this lens aims to significantly reduce glare and enhance visual outcomes for patients.

Design and Material

• Optic Design: The lens features a biconvex, monofocal, spheric optic, providing clear vision without correcting astigmatism. It is not preloaded, allowing for customized surgical handling.
• Materials: Constructed from clear poly(methyl methacrylate) (PMMA) for the optic, and black poly(ethyl methacrylate) (PEMA) for the diaphragm, with PMMA haptics. This combination ensures durability and effective light management.

Dimensions

• Overall Diameter: 12.5 mm
• Diaphragm Diameter: 10.0 mm
• Central Transparent Zone: 5.0 mm
• Optic Diameter: 3.0 mm
• Pupillary Aperture: 5.0 mm

Optical Properties

• Diopter Range: 10.0 D to 30.0 D, with a specific focus on +22.0 D
• Refractive Index: 1.49
• UV Filter: Integrated for eye protection

Implantation and Fixation

The lens is versatile in its implantation, suitable for endocapsular, sulcus, or scleral fixation. Recommended fixation involves 9-0 double-armed Prolene sutures with spatula needles. The required corneal incision is typically between 10.0 mm and 11.0 mm, with zero-degree haptic angulation for stable positioning.

Intended Benefits

This lens is intended to improve best-corrected visual acuity and reduce glare for patients with iris deficiencies. Clinical performance data indicates a strong safety profile, with effective visual improvement and a low incidence of complications such as mild postoperative anterior uveitis.

Additional Features

The Morcher 67G Aniridia IOL includes a UV filter but does not provide extra blue light control. It is also available without an optic, offering flexibility depending on patient needs. This product is not preloaded, allowing surgeons to tailor the implantation process to specific clinical scenarios.
