PRESBYOND is approached very cautiously in retinal disease and is often avoided when retinal function is significantly compromised.
Concerns in retinal pathology
Visual potential may already be limited.
- Conditions such as diabetic maculopathy or vein occlusion reduce best‑corrected vision
- Multifocal or blended optics can further reduce contrast on a compromised retina
- Progressive retinal disease may overshadow any refractive benefit
- Retinal treatment and monitoring are usually higher priorities
- Risk of dissatisfaction if expectations exceed what the retina can deliver
When it might still be considered
Only with specialist input and caution.
- Stable, mild retinal changes with good central acuity
- Retinal specialist endorses the plan
- Extensive counselling about limited and uncertain gain
- Commitment to ongoing retinal follow‑up after surgery
- Often, lens‑based or non‑surgical options are preferred instead
