Private SILK lenticule laser eye surgery, UK 2026
SILK is the Johnson & Johnson Vision Smooth Incision Lenticular Keratomileusis procedure performed on the ELITA femtosecond laser: a biconvex bi-aspheric lenticule is cut entirely inside the cornea and extracted through a sub-2 mm keyhole incision, with no flap and no excimer ablation.
Unlike LASIK that lifts a hinged flap, or first-generation lenticule extraction that uses thicker shaped lenticules and longer scan times, SILK uses a thinner biconvex aspheric lenticule and the high-pulse-frequency ELITA laser to deliver smoother stromal beds, faster optical recovery and a low induced aberration profile. UK 2026 projected self-pay is GBP 2,400-3,250 per eye in centres certified for SILK on ELITA.
Fast answer: private SILK laser eye surgery in the UK in 2026
Typical cost per eye
GBP 2,400-3,250 self-pay per eye, including consultant assessment, the ELITA femtosecond laser, theatre, drops and structured follow-up.
What it does
Cuts a thin biconvex bi-aspheric lenticule entirely inside the cornea and extracts it through a sub-2 mm keyhole, reshaping the cornea to correct myopia and astigmatism without a flap.
Procedure time
About 8-12 minutes per eye end-to-end with a laser scan time of approximately 25-30 seconds. Both eyes operated in a single attendance under topical anaesthesia.
Recovery
Functional vision typically returns from day 1, with most patients meeting the UK DVLA driving standard within 24-48 hours. No flap-related lifestyle restrictions.
What is SILK laser eye surgery on the ELITA laser?
SILK stands for Smooth Incision Lenticular Keratomileusis and is the Johnson & Johnson Vision lenticule extraction procedure performed exclusively on the ELITA femtosecond laser platform. Unlike LASIK, SILK does not lift a corneal flap and does not use an excimer laser. Instead, a single femtosecond laser session cuts a thin biconvex bi-aspheric lenticule entirely within the corneal stroma; the lenticule is then dissected and extracted through a sub-2 mm keyhole incision, with the cornea reshaped to correct myopia and astigmatism.
Two design choices distinguish SILK from first-generation lenticule extraction. First, ELITA operates at a high pulse frequency with a small spot size, delivering smoother stromal interfaces and faster post-op optical recovery. Second, the SILK biconvex bi-aspheric lenticule profile is optimised to reduce induced spherical aberration and to preserve corneal biomechanical stability compared with a standard convex-only lenticule. SILK is best understood as the second-generation flap-free keyhole laser eye surgery and sits in the same family as SMILE Pro on the Zeiss VISUMAX 800 and SmartSight on the Schwind ATOS, with which it competes for the same flap-free patient cohort. Patients not suitable for any corneal laser - because of thin corneas, high refractive errors or significant dry eye - are typically counselled towards the EVO ICL.
UK 2026 private SILK cost per eye
Private SILK is priced per eye and where available includes the consultant refractive assessment, advanced corneal topography and tomography, anterior segment OCT and corneal biomechanics, the ELITA femtosecond laser scan and lenticule extraction, the day-case theatre, postoperative drops and a structured 12-month follow-up. UK 2026 self-pay sits in the upper mid-range of the corneal refractive market because of the ELITA platform investment and the J&J certification requirements.
| Procedure | Typical UK 2026 cost per eye |
|---|---|
| SILK for myopia only (low/moderate) | GBP 2,400-2,750 |
| SILK for myopic astigmatism | GBP 2,650-3,050 |
| Bilateral SILK package (both eyes same attendance) | GBP 4,500-6,250 total |
| 12-month enhancement included where required (rare) | No further charge |
Compare with the private ICL price list for thick-cornea-unfriendly prescriptions, and the refractive lens exchange price list for presbyopic patients in their 50s and 60s. Stage payment via finance is available where the indication is met.

What does the evidence say about SILK on ELITA?
SILK on the ELITA femtosecond laser has been reported in international prospective cohort and comparative studies in the Journal of Refractive Surgery and at ESCRS, ASCRS, AAO and the Royal College of Ophthalmologists Annual Congress since the platform launch in 2022. Consolidated outcomes for myopia and myopic astigmatism within the platform range typically report uncorrected distance acuity of 6/6 or better in approximately 90-95 percent of eyes at three months, refractive accuracy within +/- 0.50 D in approximately 90 percent of eyes, rapid day-1 visual recovery comparable to modern LASIK, and a low induced higher-order aberration profile attributable to the biconvex bi-aspheric lenticule design and the smoother ELITA interface.
Dry eye scores at one and three months are favourable compared with myopic LASIK because of the much smaller incision footprint, although a transient dry eye phase is still expected and is managed with preservative-free lubricants and lid hygiene. Long-term refractive stability and ectasia safety are reassuring within the published five-year follow-up of comparable flap-free lenticule platforms, and SILK shares the same flap-free corneal biomechanical advantage. Patients with refractive errors outside the validated SILK range, with thin corneas, with high suspicion for keratoconus, or with significant dry eye remain better suited to alternative procedures.
SILK vs other refractive procedures
Choosing a refractive procedure is a trade-off between flap vs flap-free, corneal vs lens-based, the magnitude of refractive error, corneal thickness and biomechanics, dry eye risk and patient lifestyle. SILK is one of three modern flap-free lenticule platforms in the UK in 2026, alongside SMILE Pro on the Zeiss VISUMAX 800 and SmartSight on the Schwind ATOS.
| Procedure | Mechanism | Best for | Key trade-off |
|---|---|---|---|
| SILK (ELITA, J&J Vision) | Flap-free biconvex bi-aspheric lenticule extracted through <2 mm keyhole | Low/moderate myopia +/- astigmatism, healthy corneas, dry-eye risk | Newer evidence base than mature SMILE / LASIK; not suitable for hyperopia |
| SMILE Pro (Zeiss VISUMAX 800) | Flap-free convex lenticule, ultra-fast scan time | Low/moderate myopia +/- astigmatism, longest flap-free track record | Not for hyperopia; thicker lenticule than SILK |
| SmartSight (Schwind ATOS) | Flap-free lenticule with low-energy interface and cyclotorsion control | Low/moderate myopia +/- astigmatism with active torsion compensation | Smaller installed base; not for hyperopia |
| Contoura topography-guided LASIK | Flap-based, topography-customised excimer ablation | All ranges (myopia, hyperopia, astigmatism), irregular topography | Flap-related restrictions; higher dry eye than lenticule platforms |
| EVO ICL | Reversible phakic IOL behind the iris, no corneal ablation | High myopia, thin corneas, dry eyes, lens-preserving reversibility | Intraocular procedure with its own risk profile and follow-up burden |
| PRESBYOND blended vision | Bilateral micro-monovision LASIK with a custom blend zone | Presbyopes who want distance + intermediate + most near from a corneal procedure | Requires a brief neuroadaptation; not for distance-only patients under 40 |
See the in-depth SMILE Pro and SmartSight pages, and the ICL overview if your prescription, corneal thickness or dry-eye risk pushes you towards a phakic implant rather than a corneal procedure.
Are you a candidate for SILK?
Good candidates
- Adults aged 21 and over with stable myopia or myopic astigmatism within the validated SILK range and a stable refraction for the previous 12 months.
- Healthy corneas with normal Pentacam tomography and Corvis ST biomechanics, with adequate residual stromal bed thickness for SILK at the planned refractive correction.
- Patients who want a flap-free keyhole laser procedure with rapid day-1 recovery and minimal lifestyle restrictions.
- Patients with a higher baseline dry eye risk who would prefer the smaller incision footprint over LASIK.
- Active patients, contact sports, military and emergency services personnel who value the absence of a corneal flap.
Better suited to other options
- Patients with hyperopia - SILK is not currently licensed for hyperopia in the UK in 2026. Consider Contoura LASIK.
- Patients with very high myopia outside the SILK range, thin corneas or borderline biomechanics - EVO ICL is safer.
- Patients with keratoconus or any suspicion of corneal ectasia on tomography or biomechanics.
- Patients with significant cataract or established presbyopia wanting full presbyopic correction - refractive lens exchange is more definitive.
- Patients with active autoimmune disease affecting the ocular surface or recent active herpetic keratitis.
NHS vs private SILK in the UK
Refractive surgery for myopia and astigmatism is regarded by the NHS as a lifestyle indication and is not commissioned: NHS pathways centre on glasses and contact lens correction. SILK is accessed only through a private consultant-led refractive pathway at UK centres equipped with the Johnson & Johnson Vision ELITA femtosecond laser and certified for SILK in 2026. Private SILK offers same-week consultant continuity, full Pentacam tomography and Corvis ST biomechanics, ELITA-grade lenticule extraction and a structured 12-month follow-up with a 12-month enhancement where clinically indicated. See the wider treatments hub and the ICL overview for the full refractive pathway.
Insurance and funding
SILK is a refractive elective and is not typically covered by UK private medical insurers. Self-pay via interest-bearing or 0% interest stage payment plans is widely used. See insured patients for how we work with major UK insurers on any concurrent medically-indicated ophthalmic care, and finance for stage payment options on the refractive element.
Risks and limitations of SILK
SILK is a flap-free corneal lenticule procedure and shares the underlying risk profile of modern laser eye surgery: rare microbial keratitis, transient dry eye in the first 1-3 months managed with preservative-free lubricants, mild halo or glare in the first few weeks, lenticule extraction difficulty in a small minority of cases, refractive surprise from biometry or healing variability in a small minority of eyes amenable to a 12-month enhancement, and rare epithelial ingrowth at the incision site. Long-term ectasia risk is very low in well-screened eyes, and SILK shares the corneal biomechanical advantage of being flap-free. SILK is not currently licensed for hyperopia in the UK in 2026.
Recovery timeline after SILK
First 24 hours
Vision is bright but mildly hazy in the first few hours, with gritty sensation and mild light sensitivity. Drops start the same day. Most patients meet the UK DVLA driving standard at the day 1 review.
Week 1
Distance vision is functional. Drop regimen continues, preservative-free lubricants used regularly. A week 1-2 review confirms healing of the keyhole incision and titrates the schedule.
Weeks 4-6
The eye is largely stable. Vision is at or near the expected refractive target. Mild halo and glare typically settle. Most activities resumed including swimming, gym work and travel.
3-12 months
Full neuroadaptation and refractive stability. Dry eye continues to improve. A 12-month enhancement is offered at no extra charge if clinically indicated.
How to choose a UK SILK clinic
- Confirm the operating consultant is a GMC-registered refractive surgeon certified by Johnson & Johnson Vision for SILK on the ELITA femtosecond laser.
- Insist on Pentacam tomography, Corvis ST or ORA corneal biomechanics, anterior segment OCT, pachymetry and scotopic pupillometry at baseline screening.
- Ask for the surgeon's personal SILK refractive accuracy within +/- 0.50 D, retreatment rate, and 12-month uncorrected acuity outcomes.
- Confirm the clinic is CQC-regulated, with full theatre cover, an emergency pathway and a 24-hour postoperative advice line.
- Ask whether the same clinic offers EVO ICL or refractive lens exchange so any patient outside the SILK range is offered the right alternative rather than a default to SILK.
- Insist on a written, itemised quote covering the consultant assessment, ELITA laser, theatre, follow-up and any 12-month enhancement.

SILK frequently asked questions
How much does private SILK laser eye surgery cost in the UK in 2026?
Self-pay SILK in the UK in 2026 is typically GBP 2,400-2,750 per eye for myopia only and GBP 2,650-3,050 per eye for myopic astigmatism. Bilateral packages are GBP 4,500-6,250 in total. Pricing reflects the ELITA femtosecond laser platform investment, the J&J Vision SILK certification requirements and a structured 12-month follow-up including a 12-month enhancement where clinically indicated.
Is SILK available on the NHS?
No. The NHS regards refractive surgery for myopia and astigmatism as a lifestyle indication and does not commission SILK or any other laser eye surgery. SILK is accessed only through a private consultant-led refractive pathway at UK centres equipped with the Johnson & Johnson Vision ELITA femtosecond laser in 2026.
How does SILK differ from LASIK?
LASIK lifts a hinged corneal flap and uses an excimer laser to reshape the underlying stroma; SILK does neither. SILK creates a thin biconvex bi-aspheric lenticule entirely within the cornea using the ELITA femtosecond laser and extracts it through a sub-2 mm keyhole incision. No flap, no excimer ablation, smaller incision footprint and a generally lower dry eye risk.
How does SILK compare with SMILE Pro and SmartSight?
All three are flap-free lenticule extraction procedures. SMILE Pro on the Zeiss VISUMAX 800 has the longest flap-free track record. SmartSight on the Schwind ATOS adds active cyclotorsion control. SILK on the ELITA uses a biconvex bi-aspheric lenticule and a high-pulse-frequency laser to deliver smooth stromal interfaces and fast optical recovery. The choice in practice depends on which platform your surgeon is most experienced with and on your specific cornea.
What refractive errors can SILK correct?
SILK is currently used in the UK in 2026 for myopia and myopic astigmatism within the platform validated range. SILK is not currently licensed for hyperopia, very high refractive errors outside the validated range, or for primary presbyopic correction.
How long does SILK take?
Each eye takes about 8-12 minutes end-to-end. The ELITA laser scan itself is approximately 25-30 seconds. Both eyes are operated within a single attendance under topical anaesthesia.
How soon can I drive after SILK?
Most patients meet the UK DVLA driving standard at the day 1 review. You should not drive until you have been formally certified to do so by your surgeon at that visit.
How long does recovery from SILK take?
Functional vision typically returns from day 1, with steady improvement over the first week. Mild dry eye and occasional halo or glare typically settle by weeks 4-6. Full refractive stability is achieved by three months and surveyed at the 12-month review.
What are the risks of SILK?
SILK shares the modern lenticule extraction risk profile: rare microbial keratitis, transient dry eye, mild halo or glare, lenticule extraction difficulty in a small minority of cases, refractive surprise amenable to a 12-month enhancement, and rare epithelial ingrowth at the incision site. The flap-free architecture confers a long-term corneal biomechanical advantage over flap-based LASIK.
Will I still need reading glasses after SILK?
SILK corrects distance vision. Presbyopic patients in their 40s and older will still need reading glasses for near work, unless the plan deliberately includes a small monovision target on the non-dominant eye. Patients seeking distance, intermediate and most near vision from a corneal procedure are typically counselled towards PRESBYOND blended vision.
Can I have SILK if I have dry eyes?
Mild to moderate dry eye is not an absolute contraindication and may even be one of the reasons to prefer SILK over flap-based LASIK because of the smaller incision footprint. Severe dry eye, significant ocular surface disease or active autoimmune surface disease are best treated and stabilised first, and may push the plan towards EVO ICL instead.
Is SILK reversible?
SILK is not technically reversible because corneal tissue (the lenticule) is removed. However, an enhancement can be performed at 12 months if refractive accuracy is not as planned. Patients who prioritise reversibility typically prefer the EVO ICL.
Where can I book a private SILK consultation in the UK?
