PRESBYOND
A LASIK-based treatment that sets one eye mainly for distance and the other slightly for near. Your brain blends the two into one range of clear vision.
- Treats
- Presbyopia, with or without nearsightedness, farsightedness or astigmatism
- Laser
- ZEISS VISUMAX 800 for the flap, ZEISS MEL 90 with PRESBYOND software to reshape
- How it is done
- A thin layer of the cornea is lifted, then put back, as in LASIK
- After treatment
- Most daily tasks can usually resume the next day. Getting used to near and distance vision takes weeks, sometimes months
How PRESBYOND works
A few hours at the clinic. The laser itself takes moments.
Trying it first
At screening, trial lenses show whether blended vision suits you.
The flap
As in LASIK, a thin flap is made and lifted.
Two profiles
The laser sets one eye for distance and the other slightly for near.
Blending
Over the following weeks, your brain learns to combine them.
- People over about 40 whose near vision has started to fade
- Eyes that tolerate blended vision when it is tried at screening
- A healthy cornea thick enough for a LASIK-based treatment
- Eyes without early cataract; if the lens is already clouding, lens surgery may suit you better
What it does well, and where it falls short
Benefits
- Aims to give clear vision at distance, middle distance and near
- Can treat a distance prescription at the same time
- Many people use reading glasses far less often afterwards
Limitations
- You may still want glasses for very small print, dim light or long reading
- The brain needs weeks, sometimes a few months, to adapt to the blend
- Presbyopia keeps progressing with age, and cataracts can still develop later in life
Recovery
Most daily tasks can usually resume the next day. Getting used to near and distance vision takes weeks, sometimes months. Typical, not promised; healing differs from person to person.
The first day
Watery, scratchy eyes for a few hours, as after LASIK.
The first weeks
Distance returns quickly; near improves as your brain adapts.
The first months
Vision settles, and check-ups see how the two eyes work together.
Risks to talk through
Your surgeon will go through these with you before you decide.
More common
- Time to adapt
Some blur or reduced depth perception while the brain adapts.
- Dry eyes and night glare
Dry eyes, and glare or halos at night, as with LASIK.
- Glasses for some tasks
Needing glasses for some tasks, or a further adjustment.
Uncommon or rare
- Flap problems or infection
Both are uncommon.
Questions about PRESBYOND
What is presbyopia?
The normal ageing of the lens. From your forties you hold your phone further away and need more light to read.
Is it the same as monovision?
Related, but each eye also gets a wider depth of focus, which makes the blend easier for most people.
What if I already have a cataract?
Then lens surgery at Galileo may be a better route, because a new lens can address both. Your surgeon will tell you at screening.
Will I never need reading glasses again?
No one can promise that. The aim is to need them much less, and many people manage most daily tasks without them.
The other procedures
Is PRESBYOND right for your eyes?
A screening measures your eyes and ends with a plain answer.
