Customised freeform scleral lenses designed using advanced CNC lathing technology to match the full corneo-scleral profile — delivering precise, stable fits for the most complex irregular corneas.
The i-Shape Freeform Scleral lens from Appenzeller Kontaktlinsen (Switzerland) is designed using full corneo-scleral profilometry data from the Eaglet Eye ESP or equivalent platform. Every parameter — base curve, sagittal depth, haptic zone, and edge profile — is derived directly from the patient's own eye surface geometry.
Available with toric haptic options for patients with significant scleral toricity — reducing rotation, improving stability, and enhancing comfort in eyes where standard spherical haptics fail to align.
Every lens is individually lathed to a unique freeform design — not selected from a standard inventory. No two i-Shape lenses are identical.
Lens parameters derived directly from profilometry data — sagittal depth, scleral tilt, and toricity captured meridian by meridian.
Quadrant-specific toric haptic zones address scleral asymmetry — reducing edge lift and improving alignment in irregular scleral shapes.
Manufactured in Switzerland to ±0.1 µm tolerance. Appenzeller Kontaktlinsen has produced specialty lenses for over 50 years.
Full CE certification under EU Medical Device Regulation — meeting the highest European standards for safety and clinical performance.
Indicated where standard scleral geometries have failed. Designed for the most asymmetric, challenging corneal and scleral profiles.
The i-Shape is indicated when off-the-shelf or standard freeform sclerals cannot achieve adequate alignment, vaulting, or comfort. It is the tool of choice for the most complex cases.
