Description

The 68 ANIRIDIA IOL is a specialized intraocular lens designed for patients with aniridia and iris coloboma. This innovative lens serves multiple purposes, including iris reconstruction and optical correction during aphakia or cataract surgery. Its unique design allows for versatile fixation options, accommodating cases that require scleral, sulcus, or capsular bag fixation.

Key Features

• Iris Reconstruction: The lens features a colored body and haptics that mimic the natural iris, available in various pigmentation options. This design enhances cosmetic outcomes and reduces light sensitivity through tinted options.

• Optical Design: The lens is monofocal, refractive, and spherical with a biconvex optic. It includes a spherical aberration of +0.2μ and provides UV-light protection, although it does not offer blue light control or astigmatism correction.

Material Composition

Constructed from black PEMA and PMMA, the lens body is complemented by PMMA haptics. The use of black polycarbonate is noted for its fragility compared to PMMA, which may influence handling considerations.

Fixation and Implantation

The lens supports various fixation methods, including scleral fixation using 9-0 Prolene sutures, sulcus fixation, and capsular bag fixation. It is particularly suitable for cases with extreme subluxation. The lens requires a large incision of over 10.0 mm for implantation, with an overall size of 12.5 mm and a pupillary aperture of 4.5 mm.

Optical Properties

With a refractive index of 1.49 and specific A-constants for scleral suturing, the lens offers precise optical performance. The ACD constants are 5.37 and 5.90, while other optical properties such as the Abbe number and optic edge are not specified.

Color Options

Standard color options include brown, green, and blue, with black available for patient-specific designs. While the lens aims to match the color of the fellow eye, variations may occur, and the implanted color may appear lighter.

Additional Considerations

The 68 ANIRIDIA IOL addresses light sensitivity and cosmetic needs in aniridia patients. It is not preloaded and does not provide astigmatism correction or additional blue light control. These features make it a tailored solution for enhancing visual function and appearance in affected individuals.
