Official OVITZ Dealer — Netherlands & Europe

See more clearly with wavefront-guided technology

Do you suffer from halos, double vision or glare that glasses cannot correct? We correct higher order aberrations with OVITZ xwave technology — for patients with keratoconus, post-LASIK complaints and other complex eye conditions.

The science

What are higher order aberrations?

Optical aberrations can be detected in every eye. Lower-order aberrations (LOAs) such as myopia, hyperopia and astigmatism account for over 80% of all refractive errors and are easily corrected with glasses or standard contact lenses.

Higher-order aberrations (HOAs) are more complex optical errors — such as coma, trefoil and spherical aberrations — that cannot be corrected with glasses. In keratoconus, HOAs occur up to 6× more frequently.

1 Coma

Light rays through the corneal periphery are refracted differently than through the centre. Causes comet-tail distortions, very disturbing when driving.

2 Spherical aberration

Light rays at the lens edge refract differently than centrally. Causes halos and blurry edges around light sources.

3 Trefoil

Three symmetrical lobes of distortion around a light source ('cloverleaf' shape). Usually less severe than coma.

Causes

When do higher order aberrations occur?

🔬

Keratoconus

Cone-shaped cornea with severe distortion

⚡

Post-LASIK

Complications after laser eye surgery

🩹

Scarring

After infection, trauma or transplant

💧

Dry eyes

Sicca syndrome, Sjögren's

🔅

Cataract

Clouding of the eye lens

OVITZ xwave Technology

The solution: wavefront-guided scleral lenses

The OVITZ xwave system is the world's first streamlined production system for wavefront-guided contact lenses. It measures the entire optical system of the eye and designs a unique correction lens that precisely neutralises your specific HOAs.

Measurement

Complete ocular wavefront profile with the xwave aberrometer

Analysis

Automated HOA analysis and visual simulation of your vision

Design

The OVITZ algorithm designs a custom-made HOA optic

Production

Results

Measurably better vision

Clinical results show an average HOA reduction of 50%. Patients typically experience one or more lines of improvement on the acuity test, sometimes up to five lines.
