Riyan ACE is an advanced Monofocal IOL with a negative aspheric optic design. It offers many advantages compared to a normal Monofocal IOL.
Most of the spherical and standard Monofocal IOL MTF (for Modular Transfer Function) are represented below. The black line represents an ideal IOL. The blue line represents a standard Monofocal IOL.
The advanced design of Riyan ACE give a number of advantages for the patient :-
- A negative spherical aberration of -0.20µm to compensate the average corneal of most of the people. The transfer of light is very close to the Ideal IOL.
- An improvement of the depth of focus and contrast sensitivity for a better vision.
- A better vision in case of decentering and tilting of the lens. As we can see in the 2 images below, a decentering of 0.3mm and a tilting of 0.5° don’t affect much the performance of the intraocular lens.
