HYDIFF (Multifocal)

Optimum Posterior Capsular Contact

Long - term stabilization of refractive outcomes

Additional stability over traditional single - piece IOL

Square Edge against the posterior capsule limits LEC migration

Specifications

Optic type - Biconvex
A Constant - 118.9 (Theoretical Values)
Refractive Index - 1.525
A. C. Depth - 5.10 mm (Theoretical Values)
Diopter - +10.0 D to +30.0 D (with 0.5 D increments) +3.25 addition for Near Focus

Each Lens is Accompanied by Power Map & MTF Graph of Near & Far Focus

- Ensures Predictable Post-Operative refractive results
- RNI - Relative Near Intensity: 60/40 % for far and near respectively.

Advantages

- Reduces chances of halos, glare and scattering of light.
- Ensures balanced distribution of light energy
- Synchronized Clear Vision .

Limitations

- Possibility of glare.
- Creates Halos and Scattering Light.
