Onefit MED provides practitioners with complete control over their scleral lens designs and fits.  With a standard diameter of just 15.6mm, Onefit MED is unique and simplifies the fitting process for a wide range of applications. Designed to allow the practitioner to fully customise the fit, adjustments are possible in four (4) 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 Dx lenses are etched with solid lines that can be observed at the slit lamp or OCT image. Onefit MED minimises both lens thickness and tear layer, maximising oxygen transmission to the cornea and stem cells. The design serves as its own platform from which Multifocal, Oblate and Front Toric geometries can be ordered.

Onefit MED is very predictable and the final lens parameters can be determined, as well as visualised, using the Onefit MED Fitting Tool.

Onefit MED minimises both lens thickness and tear layer required to support the lens, to optimise oxygen transmission to the cornea and stems cells, for long-term ocular health.

With a trial set composed of 20 lenses, practitioners can fit:

• Irregular Corneas
• Ectactic Corneas (moderate to severe)
• Nipple & Oval Cones
• Post-RK, Post-LASIK
• Pellucid Marginal Degeneration
• Ocular Surface Disease
• Astigmatism
• Presbyopia
• Normal Prolate Corneas
• Pingueculas or other growths, shunts or scleral elevation – utilising Controlled Peripheral Recess*

Design Options for Onefit MED include:  Spherical, Multifocal, Toric, Toric Haptic, Oblate, Oblate Multifocal, Quadrant Specific, Controlled Peripheral Recess (CPR)*.

*Controlled Peripheral Recess, or “CPR” technology, is a manufacturing process that creates a precise, controlled and reproducible peripheral recess to accommodate pingueculas, scleral shunts, and other scleral elevations that may contribute to lens discomfort and/or poor lens centration. CPR technology is available in Spherical, Oblate, Multifocal, Front Toric, Toric Haptic, and Quadrant Specific specifications. Up to two recesses can be created on a lens!

The extremely user-friendly CPR Tool keeps you in total control of CPR placement and size, simplifies the design and ordering process, and provides a visual representation of the lens design.  You can connect directly to the CPR Tool, along with other innovative fitting tools, at http://prod.blcalculator.com/tools/

Benefits provided by Onefit MED lenses include superior comfort, stability of fit, vision that remains consistent throughout the wearing time, reduced glare and starbursts and reduced dryness.  Although designed for more advanced irregular patients, the attributes of this lens design also make it an ideal lens for athletes and active wearers, unhappy soft and soft toric lens wearers, and intolerant corneal GP wearers.  Onefit MED lenses offer the crisp vision of a GP while providing the comfort of a soft lens.
