Monofocal intraocular lens Akreos®

polyhydroxyethylmethacrylate

Overview
Akreos® AO60 and MI60L are aspheric hydrophilic acrylic intraocular lenses developed for microincision cataract surgery, offering a range of powers and geometries to support precise centration and stability.

Key features

• Optical design delivers quality of vision and contrast sensitivity according to published references
• High flexibility enables implantation through incisions as small as 1.8 mm
• Three overall lengths and a four‑point haptic configuration for predictable fit, centration and rotational stability
• Equi‑biconvex optic and low refractive index material to minimize reflected light

Technical data
Model | Recommended Starting A-Constant | Overall Diameter | Diopter Powers
AO60 | 118.5* | 11.0 mm (+0 to +15 D); 10.7 mm (+15.5 to +22 D); 10.5 mm (+22.5 to +30 D) | +0 D to +9 D in 1.0 D steps; +10 D to +30 D in 0.5 D steps
MI60L | 119.1* | 11.0 mm (+0 to +15 D); 10.7 mm (+15.5 to +22 D); 10.5 mm (+22.5 to +30 D) | +0 D to +9 D in 1.0 D steps; +10 D to +30 D in 0.5 D steps
*A-constants are optical biometry estimates only. It is recommended that each surgeon develop his or her own values.
