Understanding Onefit MED

About Onefit MED

The Onefit MED by Blanchard (now CooperVision Specialty) is a 15.6mm standard-diameter scleral lens designed with four independently customizable fitting zones. This modular design lets the fitter adjust the central optic, limbal clearance, and two scleral landing zones independently — a significant advantage for irregular corneas where a one-curve-fits-all approach often fails. The Onefit MED is a workhorse lens for keratoconus, post-graft corneas, and other irregular-cornea conditions.

Benefits of Onefit MED Treatment

  • Four independently adjustable fitting zones for precise customization
  • Standard 15.6mm diameter — comfortable and easy to handle
  • Excellent for irregular corneas where simpler designs struggle
  • Boston XO/XO2 gas-permeable material with high oxygen transmission
  • Modular design reduces chair time — faster, more predictable fitting

Common Questions About Onefit MED

The Onefit MED is a 15.6mm scleral lens by Blanchard (CooperVision Specialty) with four independently adjustable fitting zones. This modular design lets the fitter customize each part of the lens — central optic, limbal area, and two scleral landing zones — independently, which is a major advantage for irregular corneas.
Both are excellent scleral lenses. Zenlens (Bausch + Lomb) is available in 16.0mm and 17.0mm with prolate and oblate base curves and SmartCurve technology. Onefit MED is 15.6mm with four independently adjustable zones. The best lens depends on your corneal shape and the fitter's assessment — we stock both diagnostic sets and choose based on your anatomy.
Medical insurance often covers scleral lenses when prescribed for a documented medical condition like keratoconus (V2531 billing code). Coverage varies by plan. We verify your benefits and handle the claim submission.
Scleral lenses including Onefit MED typically cost $1,500-$3,500 per eye, which includes the custom lens, fitting process, and initial follow-up visits. Replacement lenses are less since the fitting work is already done.
