PRESBYOND and PresbyMAX are advanced laser options for presbyopia that extend focus range in different ways. Both aim to reduce dependence on reading glasses while keeping distance vision useful.
Approach to blended vision
PRESBYOND uses wavefront-optimised profiles and a blended vision concept, giving each eye extended depth of focus with a slight distance-near bias. PresbyMAX tends to create more defined multifocal zones across the cornea.
- PRESBYOND often feels like a smoother transition between distances
- PresbyMAX may produce stronger multifocal effects with noticeable zones
- Pupil size, dominance, and visual tasks influence which suits best
- Both require healthy corneas and stable prescriptions
Adaptation and patient preference
Personal preference is crucial because responses vary. Careful counselling and, where possible, contact lens trials help predict comfort.
- Some patients adapt quickly and enjoy extensive spectacle freedom with either method
- Night-time halos or reduced contrast can occur, especially early on
- Fine-detail workers may still use glasses for demanding tasks
- Long-term follow-up ensures vision remains comfortable and stable
