The Onefit™ family
Multilens manufactures Onefit scleral lenses with designs from Blanchard in Canada.
The Onefit lenses provide good comfort right from the start and are easy to fit.
Onefit is ordered with radius/base curve calculated according to corneal curvature, while Onefit MED and Onefit MED+ are ordered with sagittal height (SAG). Onefit MED and MED+ are available with more customisable options than Onefit.
Indications
Onefit is designed for the correction of regular vision defects and dry eyes as well as the correction of moderately irregular corneas, while Onefit™ MED can be used for very irregular corneas when a more customised fit is needed.
Tailored for the user
All Onefit lenses are tailor-made specifically for your customer or patient. All lenses in the Onefit family are manufactured in materials with DK values of 100 or more to be suitable for keratoconus, corneal dystrophies, irregular cornea, and post-graft.
Fitting
Onefit is fitted using a trial set and easily calculated in the Onefit online fitting tool, before ordering. Se below for links to fitting tools.
