PRESBYOND is not the best option when corneal or lens factors, lifestyle, or expectations make other treatments more appropriate.
Clinical situations favouring alternatives
Cornea, lens, or retina may dictate choice.
- Thin, irregular, or ectatic corneas unsafe for laser
- Early cataracts where lens replacement is more logical
- High refractive errors better suited to ICL or lens implants
- Significant retinal or optic‑nerve disease limiting visual potential
- Severe dry eye or autoimmune surface disease
Preference‑based reasons
Goals and tolerance influence suitability.
- Mild presbyopia manageable with simple readers
- Heavy night drivers or those extremely sensitive to halos
- Strong desire for reversibility rather than permanent corneal reshaping
- Contentment with current spectacles or contact lenses
- Better alignment with lens replacement or ICL given age and lifestyle
