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 performed by consultant refractive surgeons at our South England partner clinics, with UK-wide guidance through your assessment. 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.
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.
Wondering whether PRESBYOND, distance LASIK or a lens-based option suits your eyes and lifestyle?
Book your suitability assessmentRecovery timeline
Day 2–3
Most patients are back to office work and screens. Vision is functional but the brain is still learning to blend the two eyes.
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?
UK 2026 self-pay PRESBYOND typically costs £4,800–£6,800 for both eyes all-inclusive, with most reputable London refractive centres in the £5,200–£6,400 range. The fee should cover the refractive consultation, full diagnostic work-up (Pentacam, OCT, wavefront, dry-eye assessment), femtosecond flap, MEL 90 ablation, theatre, surgeon, drops and 12 months of follow-up. Most clinics offer 0% finance over 24 months, typically £200–£285 per month subject to status. Always ask for one written all-in figure for both eyes. See our full price list for comparison.

What is the difference between PRESBYOND and standard LASIK?
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.
Will I be completely free of glasses after PRESBYOND?
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.
Should I have PRESBYOND or refractive lens exchange (RLE)?
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.
How long is the recovery after PRESBYOND?
Most patients are back to office work and screens at day 2–3, driving comfortably in daylight from day 3–7, and fully neuro-adapted to the blend at 4–12 weeks. 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.
Does private medical insurance or the NHS cover PRESBYOND?
No. As with all elective refractive laser surgery in the UK, PRESBYOND is treated as a self-pay procedure by Bupa, AXA, Aviva, Vitality and WPA, and it is not funded by the NHS, which regards refractive surgery as a lifestyle indication. Most clinics offer 0% finance over 24 months as an alternative to upfront payment.
