homei-shape-freeform-the-new-standard-for-scleral-lenses
At Chris Geysen Contact Lenses, we work with Appenzeller freeform scleral lenses (i-Shape). This is the latest generation of scleral lenses, designed entirely based on the actual shape of your eye.
Not a standard lens, but pure customisation. The new standard in scleral lenses.
The i-Shape is a freeform scleral lens that is no longer fitted using only trial lenses, but is calculated entirely digitally. Your eye is measured biometrically and translated into a lens that fits exactly.
With more than 160,000 measurement points per eye, we obtain an extremely accurate image of your ocular surface.
The result? A lens that fits like a fingerprint.
Traditional scleral lenses start from a standard shape and are then adjusted. Freeform works the other way around: we start with your eye.
Freeform lenses are based on profilometry and make it possible to successfully complete even difficult fittings.
The i-Shape lens is thin, oxygen-permeable, and remains stable on the eye.
Due to the exact fit, the lens often fits correctly right away, with less need for subsequent adjustments.
We combine i-Shape with advanced measurements such as profilometry. This allows us to:
For us, freeform scleral lenses are not a niche, but a logical step in modern contact lens care.
We have a strong focus on scleral lenses and customisation. i-Shape fits perfectly within that vision: using technology to achieve better results for the patient.
Would you like to know if freeform scleral lenses are right for you? We will evaluate this together and find the solution that truly works for your eyes.
