PRESBYOND can act as a surgical alternative to reading glasses by extending the range of clear vision, but it is not a simple replacement for everyone.
When it functions well as an alternative
It targets presbyopia directly.
- Presbyopes heavily reliant on readers or varifocals for daily tasks
- Stable prescriptions and healthy corneas and lenses
- Strong motivation to reduce or eliminate near‑spectacle dependence
- Comfort with blended‑vision optics and possible night‑vision changes
- Understanding that occasional glasses may still be helpful for very fine print
When reading glasses remain the better option
Non‑invasive solutions often suffice.
- Mild presbyopia where low‑cost readers are needed only occasionally
- High sensitivity to risk or even small changes in visual quality
- Ocular or systemic conditions increasing surgical risk
- Patients who are generally happy with their current spectacles
- Those who prioritise maximum sharpness for prolonged reading over spectacle freedom
