Onefit MED

Onefit MED has a larger diameter with 15,6 mm as standard. Onefit MED is an intuitive scleral lens that provides you with control to customize the ideal lens for highly irregular and medically indicated cornea or even normal corneas when a larger diameter is needed. Designed to allow the practitioner to fully customize the fit, adjustments are possible in four separate zones of the lens (Central, Mid-peripheral, Limbal and Edge). To easily find the exact location of the Mid-Peripheral and Limbal zones, the diagnostic lenses are etched with solid lines that can be observed at the slit lamp or OCT image.

Onefit MED is fitted after sagittal height (SAG) and can be ordered from SAG 3800 to 6200 micron

Onefit MED is available spheric, front toric, multifocal and with toric periphery, in prolate or oblate / revers geometry design

Unstable vision with soft contact lenses. Intolerance to soft or corneal RGP contact lenses

Corneal astigmatism or high ametropia

Irregular cornea. Post graft. Dry eyes. Post Lasik/Lasek

Onefit MED Fitting tool


Onefit MED+

When you need to cover a greater area of the eye or want the lens to bridge over larger irregularities.

Onefit MED+ is therefore best suited for

  • highly irregular corneas
  • post-surgical corneas
  • eyes with ocular surface diseases including dry eye syndrome


Onefit MED+ is the same advanced scleral lens as the original Onefit MED but in a 17.0 mm diameter.

The increased diameter creates a larger landing zone for precise alignment, a soft landing on the conjunctiva, and a healthy environment for the eye.

You control the design and fit to customize the ideal lens for each patient by selecting the parameter options for these four fitting zones:

  • Central (C)
  • Mid-peripheral (M)
  • Limbal zones (L)
  • Edge configurations (E)
