Flow3 Technology explained
Flow3 is a touch-free, cut-free surface procedure: no incision and no flap are made in the cornea. Recovery takes about a week, the eye keeps its natural strength, and your chosen package comes with a guarantee of up to 10 years.
Flow3 is a touch-free surface procedure performed entirely with the Schwind Amaris 1050RS laser, without making any cuts to the eye. Recovery is natural and smooth, allowing you to quickly return to your normal active lifestyle.
In 2016, KSA Vision Clinic updated the Flow3 procedure with SmartSurfACE and SmartPulse technologies, developed by Schwind EyeTech. In 2018, we introduced the Schwind Amaris 1050RS laser with SP6.1 software and the Intelligent Thermal Effect Control (ITEC) system, which made surface laser treatments safer and more precise. From 2025, procedures are performed with the latest Schwind Amaris 1050RS model.
From 25 October 2026 KSA's operating suite runs on the SCHWIND Signature Line — Schwind's newest package built around the same Amaris 1050RS platform: a redesigned user interface, advanced presbyopia planning modules, enhanced Foresight, therapeutic TheraCare and connected data management through ATRIUM. The procedure itself stays the same incision-free surface treatment. From the same date, KSA's Presbyopia Project starts together with Schwind's application specialists.
Recovery takes about a week. KSA Vision Clinic's 24/7 patient support is there for you throughout, and lifestyle restrictions after the procedure end on day 5–8, so Flow3 also suits people with an active lifestyle.

Which treatment plan fits your eyes? We work it out at the Flow3 eye exam.
Equipment we use for eye examinations
For eye exams we use digital measuring instruments. They give accurate, consistent results.
Diagnostic deviceThis device measures the front of the eye in one second. SCHWIND SIRIUS+ maps the shape and thickness of the cornea for treatment planning.
Scheimpflug + Placido combination
Combining both technologies provides precise detail for both corneal surfaces, detecting subtle structural irregularities that surface topography alone cannot show.
- Diagnostic accuracy in detecting keratoconus (Sirius Scheimpflug–Placido)ScienceDirect, 2026
- Repeatability of higher-order corneal aberration measurementsEye and Vision (Springer Nature), 2022
All features
- Measures pachymetry, elevation, curvature, and power for front and back corneal surfaces
- Complete anterior segment diagnosis in one step
- Transfers cyclotorsion correction data to Schwind Amaris lasers

- Glaucoma screening and pupillography (pupil diameter analysis)
- Dry eye analysis (tear film, meibomian glands, tear meniscus)
Clinical use at KSA (Dr Ants Haavel)
- The Scheimpflug camera images the entire anterior segment in cross-section — from the cornea to the lens — in a single acquisition.
- Scheimpflug lens images help assess the state and progression of cataracts.
- We use it to diagnose dry eye and track treatment outcomes over time, not just for a single snapshot assessment.

Additional information
No, it is painless. Numbing drops go in before the treatment starts. You spend about 15 minutes in the room and the surgeon talks with you throughout.
About a week. Sport and swimming are fine once the protective contact lenses are removed. Restrictions end on day 5–8.
People aged 18–45 with confirmed myopia. Whether it suits your eyes is decided at the Flow3 eye exam.
The operation is the same in every package; the difference is the guarantee and the aftercare: Flow3 Solo €2490 (1-year guarantee), Flow3 €2990 (7-year guarantee), Flow Signature Line €5990 (10-year guarantee). If needed, a repeat procedure is free during the guarantee; about 2.9% of patients need one.
KSA's operating theatre starts working with a new SCHWIND AMARIS 1050RS laser. It replaces the current laser. The procedure stays the same cut-free treatment.
Usually only 5–10 seconds. For higher prescriptions it can be 20–30 seconds. The procedure is quick and painless.
The laser delivers over a thousand light pulses per second. This keeps the procedure very short. The eye does not dry out during treatment.
About 15 minutes. The laser works for only a few seconds per eye. It is painless throughout and the surgeon talks with you.
Yes. In one independent study, active eye tracking cut the need for retreatment from 8.2% to 2.2%. The Amaris 1050RS tracking works on the same principle.
The laser follows the eye continuously. If you move your eye or blink, the laser stops automatically. It then resumes from exactly the same spot.
The tracker registers even tiny movements and places every pulse correctly. This keeps the treatment safe and the result reliable.
Only a very thin layer. It is many times thinner than a human hair. The procedure is gentle and precise.
The correction is planned precisely for your eye. It matches the eye's natural optics. The result is clear, stable vision.
Every eye is unique – that’s why every Flow3 procedure begins with a detailed corneal map and precise measurements, allowing us to customise the laser pattern specifically to your eyes. The result is accurate and personalised vision correction.
KSA Vision Clinic is the only clinic in Estonia using the Schwind Amaris 1050RS together with SmartSurfACE technology. This means a precise, short procedure and recovery in about a week.
Unlike traditional methods that require a corneal incision or mechanical lens removal, Flow3 is completely touch-free. The cornea retains its natural strength and heals naturally, making it suitable for people with an active lifestyle and for those with thinner corneas.
Do you want to know if Flow3 laser eye surgery is right for your eyes?
Book an eye examination – it’s the first step towards clarity and a life without glasses. The examination will give you a clear answer on whether your eyes are suitable for myopia correction with Flow3.
