PRESBYOND is a type of laser blended‑vision procedure for presbyopia, suited to adults who tolerate monovision‑style correction and have healthy eyes.
Typical candidate profile
Several criteria overlap with other presbyopic lasers.
- Presbyopic age group with bothersome near‑vision symptoms
- Stable low‑to‑moderate myopia or hyperopia within laser ranges
- Healthy corneas, clear lenses, and good retinal status
- Good binocular vision and ability to adapt to slight focus difference between eyes
- Successful in monovision contact lens trials, where used
Who may be less suitable
Some visual systems struggle with blended vision.
- Very strong eye dominance or intolerance of monovision trials
- Significant anisometropia or amblyopia
- Occupations demanding maximum stereopsis and fine depth judgement
- Corneal, lens, or retinal disease limiting expected acuity
- People uncomfortable with the concept of different targets in each eye
