PRESBYOND is Carl Zeiss laser blended vision, a customised femto-LASIK treatment for presbyopia. It uses an aspheric profile to expand each eye’s depth of focus plus a small monovision offset (about −1.25 to −1.50D in the non-dominant eye), so the two in-focus zones overlap and your brain fuses them into one continuous range — from reading distance to the horizon — reducing your need for reading glasses.
What is PRESBYOND?
From your mid-40s the eye’s natural lens stiffens (presbyopia) and reading glasses become necessary even after standard distance laser. PRESBYOND addresses this directly. Rather than the large offset of traditional monovision — which forces the brain to suppress one eye per task — PRESBYOND combines a smaller offset with a customised aspheric ablation that widens each eye’s depth of focus, so the focused zones overlap and the brain blends both images. Published data show better contrast, faster adaptation (median two weeks versus six) and a much lower failure-to-adapt rate than conventional monovision.
It is a private, self-pay treatment; Precision Vision London, the clinic we work with for laser eye surgery, lists its own Blended Vision from £2,500 per eye and performs it at 22A Harley Street, London, with Dr CT Pillai leading its laser service; it uses PresbyMAX on the SCHWIND AMARIS laser rather than Zeiss’s PRESBYOND. A tolerance trial before surgery confirms you adapt to the blend; PRESBYOND is best suited to healthy presbyopic eyes with a clear natural lens, typically from the mid-40s to early 60s.
Who is a good candidate for PRESBYOND?
PRESBYOND is typically suited to people aged roughly 45–65 who are presbyopic and want to reduce their reliance on reading glasses and varifocals. Good candidates usually have:
- Established presbyopia (the everyday need for reading glasses)
- A healthy, suitably thick cornea with no significant dryness or surface disease
- A stable prescription, which may also include short sight, long sight or astigmatism to correct at the same time
- No significant cataract — if the lens is already clouding, lens-based surgery is usually the better choice
A detailed pre-operative assessment with corneal scanning and a dominance and tolerance check confirms suitability. If laser is ruled out, your surgeon will discuss refractive lens exchange or other laser eye surgery options.
PRESBYOND vs other options
How PRESBYOND is performed
Treatment is an outpatient femto-LASIK procedure under anaesthetic drops — no injection, no general anaesthetic. After your full diagnostic work-up (Pentacam, OCT, wavefront and dry-eye assessment) and a tolerance trial of the blend, the femtosecond laser creates a thin corneal flap and the Zeiss MEL 90 excimer laser applies the customised aspheric profile to each eye, with the planned small offset on the non-dominant eye. The flap is repositioned and seals without stitches. Both eyes are treated in the same session and you go home the same day with lubricating drops. Precision Vision London’s Blended Vision uses PresbyMAX on the SCHWIND AMARIS laser instead of Zeiss’s lasers, so ask at your consultation which technique and lasers will be used for your eyes.

Recovery timeline
Day 2–3
Vision is functional but the brain is still learning to blend the two eyes. Precision Vision London asks its patients to wait until their first post-operative check, when Dr CT Pillai examines the eyes and advises on work, driving and the next steps.
Day 3–7
Comfortable daytime driving for most patients, once you meet the legal vision standard and feel confident.
Weeks 4–12
Full neuro-adaptation to the blend, with near and intermediate vision steadily improving. Lubricant drops are used for 3–6 months.
12 months
Final refractive outcome documented. If the blend is not tolerated, the non-dominant eye can be re-treated to full distance.
How much does PRESBYOND cost?
Precision Vision London lists Blended Vision from £2,500 per eye, or from £5,000 for both eyes (our arithmetic: Precision Vision London says to double its per-eye price); its Blended Vision uses PresbyMAX on the SCHWIND AMARIS laser rather than Zeiss’s PRESBYOND. It says every price is all-inclusive — the consultation and diagnostics, the procedure, medications, protective eyewear, 12 months of follow-ups and any enhancement within the first year — and that Advanced Wavefront technology is standard on all its laser procedures at no extra charge. Precision Vision London’s laser consultation is free, with a £100 holding fee refunded when you attend and meet its eligibility checks, and Precision Vision London’s deposit is £250 per eye, deducted from the total. Precision Vision London says 0% APR finance is available over 12 months on selected treatments, with longer plans at 9.9% APR over 24 to 60 months, subject to status. Other clinics set their own prices and payment terms, so always ask for one written figure for both eyes; Eye Surgery Clinic does not lend money or arrange finance. See our Presbyond cost page, the London laser eye surgery cost page and our full price list.

PRESBYOND FAQs
Precision Vision London lists Blended Vision (PresbyMAX on the SCHWIND AMARIS laser, not PRESBYOND) from £2,500 per eye, or from £5,000 for both eyes (our arithmetic: Precision Vision London says to double its per-eye price), and says the price includes the consultation and diagnostics, the procedure, medications, protective eyewear, 12 months of follow-ups and any enhancement within the first year. Other clinics set their own prices, so always ask for one written figure for both eyes.
Standard LASIK aims for both eyes fully corrected for distance and accepts that reading glasses will still be needed after about age 45. PRESBYOND uses a customised aspheric profile that expands each eye’s depth of focus and a small monovision offset (about −1.25 to −1.50 dioptres in the non-dominant eye) so the two depth-of-focus zones overlap and the brain blends them into one continuous range from reading distance to the horizon. About 95–97% of suitable patients are spectacle-independent for the majority of daily tasks at one year.
Approximately 95–97% of suitable patients are spectacle-independent for distance and intermediate, and 80–90% are spectacle-independent for normal print (N6) at one year. A small minority still use reading glasses for prolonged fine print or in poor light. PRESBYOND does not promise zero glasses for every task; it promises a continuous binocular range of clear vision for the great majority of daily activities.
Generally PRESBYOND is preferred for healthy presbyopic patients in their mid-40s to early 60s with a clear natural lens, and RLE with an EDOF or trifocal IOL is preferred from the early 60s onward, especially if early cataract changes are present on slit-lamp examination. The decision depends on lens clarity, pupil size, lifestyle, dry-eye status and personal preference. Both are discussed openly at consultation.
PRESBYOND typically suits presbyopic patients aged around 45–65 who want to reduce reliance on reading glasses, have a healthy and suitably thick cornea, a stable prescription and no significant cataract. It can correct short sight, long sight or astigmatism at the same time. A full assessment with corneal scanning and a tolerance check confirms suitability; if laser is ruled out, refractive lens exchange is discussed instead.
Precision Vision London asks its patients to wait until their first post-operative check, when Dr CT Pillai examines the eyes and advises on work, driving and the next steps. Full neuro-adaptation to the blend takes 4–12 weeks, and lubricant drops are used for 3–6 months. The final refractive outcome is documented at 12 months, and if the blend is not tolerated the non-dominant eye can be re-treated to full distance.
No. As with all elective refractive laser surgery in the UK, PRESBYOND is generally not covered by private medical insurance — check with your insurer what your policy covers — and it is not funded by the NHS, which regards refractive surgery as a lifestyle indication.
