ForeSight AI:
simulating the result before surgery.

In refractive surgery, the patient trusts the surgeon. But trust should not replace information. The patient has the right to see what will happen to their cornea before deciding whether to have surgery — not afterwards.

SCHWIND ForeSight is predictive simulation software integrated into the AMARIS ecosystem. It creates a virtual replica of the patient's cornea and allows us to simulate the exact effect of the laser treatment on that specific cornea, with those specific data. It is not a generic illustration: it is an individual calculation.

How ForeSight works

The process is linear. The patient's diagnostic data — topography, tomography, pachymetry, epithelial map — are acquired by the MS-39 tomographer and the Peramis aberrometer. This data feeds the SCHWIND CAM planning software, which calculates the personalised ablation profile for the AMARIS 1050RS laser.

ForeSight intervenes at this stage: it takes the virtual replica of the cornea and mathematically subtracts the calculated ablation profile. The result is a three-dimensional map of the simulated post-operative cornea — curvature, refractive power, aspherical profile — visible on screen as on any diagnostic instrument.

The surgeon can thus perform a dry run — a rehearsal of the procedure — and verify the expected result before touching the eye. If something in the simulated profile is not optimal, the planning is modified. The patient is not involved in these technical iterations, but benefits directly: when the surgeon presses the button, they already know what to expect.

What changes for the patient

In a clinic without ForeSight, the patient asks: "How will my procedure go?" The surgeon responds with general statistics: "95% of patients achieve 10/10." These statistics are real, but say nothing about their specific case.

With ForeSight, the surgeon shows the patient their simulated cornea after the procedure. Not an average cornea, not a statistic — theirs. The patient sees the expected keratometry, the anticipated aspherical profile, the safety margins relative to residual thickness. The decision shifts from "I trust you" to "I have seen the data and I decide".

An integrated ecosystem, not isolated software

ForeSight is not a generic application that works with any laser. It is a component of the SCHWIND ecosystem: it works exclusively with data from SCHWIND diagnostic devices (MS-39, SIRIUS) and ablation profiles calculated by SCHWIND CAM for the AMARIS laser.

This is not a limitation — it is the reason it works. The diagnostic data and ablation profile speak the same language: same grid, same algorithms, same calibration. No conversion, no approximation, no "import" from one manufacturer's instrument to another's laser. The data flow is native end to end.

In our clinics, the entire pathway — from the first measurement to the simulation, from profile calculation to ablation, from intraoperative verification to post-operative follow-up — takes place within a single coherent ecosystem: MS-39 → Peramis → SCHWIND CAM → ForeSight → AMARIS 1050RS. Every data point is tracked, every step is verifiable.

Clinical validation

ForeSight is not a concept: it is clinically validated software. A study published in BMC Ophthalmology in 2025 compared the corneal geometries predicted by ForeSight with real post-operative measurements on 52 eyes treated with the AMARIS laser. The results showed a significant correlation between simulation and real outcome, confirming the predictive reliability of the system in daily clinical practice.

From simulation to real-time verification

ForeSight simulates before the procedure. But on the day of the laser, the AMARIS 1050RS verifies in real time that everything matches the plan: pupillary offset, cyclotorsion, intraoperative pachymetry, corneal OCT during ablation. The simulation predicts; the laser confirms. Two levels of safety that complement each other.

Why not all centres offer it

ForeSight requires the complete SCHWIND ecosystem: MS-39 diagnostics, Peramis aberrometer, CAM software, AMARIS laser. Most centres use diagnostic instruments from one manufacturer and a laser from another — a combination that works, but does not allow integrated simulation. It is not a question of surgical competence: it is a question of technological infrastructure.

In Switzerland and Europe, very few centres have the complete SCHWIND ecosystem with operational ForeSight. Our four clinics — Lausanne, Yverdon, Geneva and Mendrisio — are among them.

ForeSight and the choice of ablation profile

The AMARIS 1050RS laser does not apply a single type of treatment. The SCHWIND CAM software offers three distinct ablation profiles, each with different indications. ForeSight allows us to simulate the result of each on the patient's specific cornea — and therefore to choose the optimal profile before operating, not in hindsight.

1. Aberration-Free (aspherical)

The standard profile for the majority of corrections. Corrects the refractive error (myopia, hyperopia, astigmatism) without inducing high-order aberrations. Preserves the natural aspherical profile of the cornea. It is the profile indicated for regular corneas with a normal aberrometric profile — the most frequent situation.

2. Corneal Wavefront-Guided

Profile guided by the corneal wavefront, measured by MS-39 topography. In addition to correcting sphere and cylinder, it treats high-order aberrations of the cornea — coma, trefoil, spherical aberration. Indicated for irregular corneas, asymmetric astigmatisms, secondary treatments or post-surgical touch-ups. ForeSight is particularly valuable here: the simulation shows whether correcting corneal aberrations produces a real benefit or risks disrupting the balance with the internal aberrations of the crystalline lens.

3. Ocular Wavefront-Guided

Profile guided by the total ocular wavefront, measured by the Peramis aberrometer. Corrects aberrations of the entire visual system — cornea + crystalline lens + vitreous. It is the most personalised profile, indicated when internal and corneal aberrations interact unfavourably. ForeSight simulates the impact of the treatment on corneal geometry and allows verification that correcting total aberrations does not negatively alter the corneal profile.
