PresbyMAX and PRESBYOND are both laser strategies for presbyopia that extend focus range, but they use different optical concepts. Understanding their nuances helps tailor treatment to your visual needs.
Optical design differences
PresbyMAX typically creates explicit multifocal zones across the cornea. PRESBYOND uses a blended vision approach, extending depth of focus while setting one eye slightly more for distance and the other for near.
- Both aim to reduce dependence on reading glasses for everyday tasks
- PRESBYOND often relies on subtle differences between the eyes
- PresbyMAX may produce a more classic multifocal pattern
- Corneal shape, pupil size, and dominance influence which suits you best
Adaptation and expectations
Both techniques require brain adaptation and honest discussion about compromises. Personal preference plays a big role.
- Some patients prefer PRESBYOND’s smoother blend between distances
- Others do well with PresbyMAX but may notice more pronounced halos
- Trial contact lenses simulating blended vision can be very helpful
- Careful counselling ensures you understand likely night and fine-detail performance
