MI60 - SALIENT FEATURES
Design optic
Design haptic

• Suitable for sub-2 mm injection without
  compromising quality of vision
• aspheric aberration-free optic
• 360 posterior barrier and square-edge design
• moderate refractive index
• 30 thinner than parent design
• 3D-deformable four-point haptics are the next
  generation haptic design seen in Akreos AO Micro
  Incision Lens only

• Provide consistent three-dimensional
  stability
• capitalizes on stability features of parent
  designs
• four-point capsular bag fixation with three
  overall diameters
• overall diameter varying with diopters
• average 10 angulation
• innovative haptic shape
