The first fully personalised LASIK treatment of it's kind.
Ray-Tracing Guided LASIK is a fully customised laser vision correction surgery that uses 3D ray‐tracing technology to scan each eye for a completely personalised outcome and significantly improved vision for whatever life might bring.
Focus Clinics' state of the art procedure uses Sightmap's Innoveyes diagnostic tool to create a custom, virtual 3D model of your eye.
This personalised model guides a highly customised procedure that can correct visual acuity and subtler, more complex vision problems.
This revolutionary technique allows surgeons to correct not just basic refractive errors (short-sightedness and astigmatism) but also subtle imperfections in the eye's optics.
We're thrilled to be the first in the UK to offer this technology, which offers the potential to achieve vision far better than 20/20 in the majority of patients.

Ray-Tracing: LASIK Evolved
What Is Ray Tracing?
The digital cloning technology (WaveLight Plus) provides a personalised treatment based on your own unique eye rather than the prescription glasses you wear. Previously, treatments were the same between individuals if they wore the same glasses.
Using this advanced diagnostic technology, we trace how up to 2,000 beams of light move through your eye with microscopic precision of 1/100,000 of a millimetre. The Sightmap Innoveyes scanner technology also measures all the components of the eye, such as the length of the eyeball and its curvature.
Creating an Eyevatar
Knowing the shape of the eye and how it processes the 2,000 beams of light, a digital copy of your eye is created that understands precisely how each ray of light moves through your eye as it gets refracted and focused by the cornea and lens.
This personalised, multidimensional, 3D model of the eye, called the ‘eyevatar’, is invaluable as we can now virtually treat your eye and safely determine the best possible personalised treatment pattern before you have your actual physical procedure.
The Results of Ray-Tracing
This means increased safety and better vision results. In fact, in trial results, the majority of patients achieved supervision of 20/12 or even better.
For the first time, we are now offering true ‘personalised’ laser eye correction, employing tracking technology that allows the laser to move faster than the eye, simultaneously detecting and accommodating any eye movements like never before during the procedure.
For the first time, surgeons are now moving beyond 20/20 to achieve high-definition vision.

Frequently Asked Questions
Ray-Tracing Guided LASIK is an advanced laser vision correction procedure that creates a highly detailed 3D digital twin of your eye, known as an Eyevatar, using over 100,000 data points.
This virtual model allows surgeons to test and refine your personalised treatment before performing the actual surgery, ensuring the best possible visual outcome.
Ray-Tracing Guided LASIK provides superior results, with over 50% of patients achieving supervision (20/12 or better).
Unlike traditional LASIK, which relies on standardised measurements, Ray-Tracing Guided LASIK customises the procedure for each patient using a digital 3D model of their eye.
This Eyevatar undergoes multiple virtual treatments before surgery, ensuring precise correction.
The technology also improves night vision and reduces side effects, with 89% of patients seeing better than 20/20 compared to 76% with wavefront-optimised LASIK.
You may be eligible if you:
- Are over 18 years old;
- Have a stable prescription;
- Are short-sighted (up to -11.00) with astigmatism (up to 4.50);
- Have no previous eye surgery;
- Have healthy eyes with no conditions that could affect healing;
Not sure if you’re suitable? Schedule a free, no-obligation phone consultation with one of our experts and they’ll be able to tell you which treatment is right for you.
There are several benefits to Ray-Tracing Guided LASIK, including:
- You get 100% personalised treatment based on your Eyevatar for precise correction;
- Incredible results, with 100% of patients achieving 20/20 vision or better and more than 50% achieving supervision (20/12 or better);
- Enhanced night vision with reduced spherical aberration;
- Minimised side effects compared to traditional LASIK.
Ray-tracing technology traces up to 2,000 individual rays of light through your eye, mapping how they bend and interact with internal structures.
This allows for an unparalleled level of personalisation, resulting in sharper focus and reduced optical distortions.
Clinical studies have shown no significant increase in optical aberrations, and contrast sensitivity (ability to see subtle shade differences) is actually improved.
The results for Ray-Tracing Guided LASIK are incredible:
- 100% of treated eyes achieved 20/20 vision or better;
- 89% of patients saw better than 20/20;
- 51% achieved supervision (20/12 or better);
- And 8% reached 20/10, the absolute limit of human vision.
These results make it the most advanced laser eye surgery available today.
The surgery itself takes around 10 to 15 minutes per eye.
However, you should expect to be at the clinic for a few hours to allow for pre-procedure checks and post-procedure monitoring.
No, numbing eye drops are used to ensure a painless procedure. Most patients feel only mild pressure during surgery.
Some minor discomfort, such as dry eyes or irritation, may occur for a few days post-surgery.
Most patients experience improved vision within 24 hours. Full visual stability may take a few weeks as the eyes heal.
During this time, mild light sensitivity and dryness are common but usually temporary.
A significant improvement in vision is noticeable within the first 24 hours, with further refinements occurring over the next few weeks.
Yes, the results are long-lasting. However, natural ageing processes such as presbyopia (age-related long-sightedness) may still occur, potentially requiring reading glasses later in life.
Ray-Tracing Guided LASIK has a low risk of complications, but possible side effects include:
- Temporary or persistent dry eyes;
- Night vision issues (rare, and significantly reduced compared to traditional LASIK);
- Under or overcorrection (only 0.3% of cases);
- Corneal flap problems (extremely rare).
Your surgeon will discuss all risks during your consultation so you have complete peace of mind prior to going ahead with any treatment.
Ray-Tracing Guided LASIK is an advanced, premium vision correction solution that goes beyond standard LASIK, offering unmatched precision and personalisation.
Rather than being a one-size-fits-all treatment, it creates a fully customised Eyevatar (a digital twin of your eye) allowing the procedure to be tested and refined before surgery even begins. The result is superior visual outcomes, better night vision, and reduced side effects compared to traditional laser eye surgery.
Focus Clinics are the only clinic in the UK to offer this procedure, and for those who want the absolute best results, Ray-Tracing Guided LASIK is the most advanced option available today.
