PRESBYOND is often better than lens replacement for younger presbyopes with clear lenses who wish to avoid intraocular surgery.
Scenarios favouring PRESBYOND
Preserving the natural lens is advantageous.
- Age roughly 40-55 with minimal lens opacity
- Good natural contrast and accommodation for intermediate tasks
- Suitability for corneal laser and blended‑vision optics
- Low tolerance for intraocular risks such as infection or retinal detachment
- Desire to defer lens surgery until cataracts truly justify it
When lens replacement is preferable
Lens changes or goals point to IOLs.
- Early cataract or lens‑related glare already affecting vision
- Age typically over 55-60 where cataract is likely in the nearer term
- Wish for a once‑off procedure addressing both presbyopia and lens ageing
- Corneal contraindications to laser, such as thin or irregular corneas
- Suitability for multifocal or EDOF lenses with acceptable risk profile
