Aspheric AF

Product catalog summary
Specifications:
The SeeLens AF and BunnyLens AF are intraocular lenses (IOLs) designed for placement in the capsular bag. They have an overall diameter of 13 mm and 11 mm respectively, with optic diameters of 6 mm. The power range for these lenses varies from -5.0 to +40.0 diopters, with different increments depending on the power range. The lenses feature an aspheric optic design with a 360° continuous square edge and a haptic angulation of 5°.
Material and Design:
These IOLs are made from hydrophilic acrylic material with a bonded UV absorber and violet light filter, providing a refractive index of 1.46 when hydrated at 35°C. The A-constant for optical or immersion ultrasound biometry is 118.9 for SeeLens AF and 118.5 for BunnyLens AF, while for contact ultrasound biometry, it is 118.56 and 118.16 respectively. The lenses are sterilized using steam.
Performance and Features:
The Aspheric AF IOLs are known for their excellent biocompatibility and mechanical quality. They incorporate a violet filtering chromophore for enhanced retinal protection. The aspheric optical design ensures aberration-free vision, providing high-quality vision in both day and night conditions. The lenses are available in a preloaded configuration for ease of use.
Optical Performance:
Graphs indicate the modulation transfer function (MTF) values under various conditions, showing the lenses' performance in night conditions, sensitivity to decentration, and sensitivity to tilt. The aspheric design offers superior performance compared to spherical IOLs, maintaining stability and centration.
