    iSee ortho-k lenses

    The iSee ortho-k contact lens is our most advanced orthokeratology lens with a level of customization that matches the doctor and the patient’s needs. Originally receiving FDA approval in 2002 as the Fargo lens and then renamed to iSee, the lens has been prescribed to tens of thousands of wearers around the world. This lens is ideal for patients with moderate to advanced myopia with and without astigmatism and for doctors who prefer to customize an ortho-k lens design.

    The proprietary MM One™ profile optimizes a custom retinal defocus which is one of the core principles of managing myopia.

    The lens delivers reliable and predictable results thanks to the state-of-the-art design algorithms that are based on big data from 18 years of proven efficacy.

    With a track record of two decades of individualized customization, the design supports multiple case complexities for varying degrees of treatment. Ideal for the eye care practitioner who favors customized designs and the lens is straightforward to prescribe either empirically or using a trial set.  

    The proprietary MM One™ profile optimizes a custom retinal defocus. The advanced design increases mid-peripheral steepening on the cornea. 

    We are confident with the success rates and excellent track record and are able to offer one of the most risk-free warranty policies in the ortho-k industry.

    Prescribing iSee is straightforward, either empirically with K’s, Rx and topography or using a trial set. Using exam data, the iSee calculator can be used to select an initial lens.

    The lens has FDA Approval for myopia correction. It is approved in the United States, Korea, China, Malaysia, and Vietnam.

    Lens Benefits


    • The iSee design includes 6 curves and gas permeable optics that deliver customization for myopia management
    • Adjustable optic zone to optimize hyperopic defocus optics.
    • The aspheric base curve determines the mold for the treatment zone: The treatment zone is the part of the lens that will flatten the cornea and can be adjusted to the amount of myopia in diopters you want to correct.
    • The Reverse Curve is carefully calculated to create high mid-peripheral plus and myopic defocus. It allows the hydraulic forces to flatten the central cornea and form a mid-peripheral ring that may be observed in a topography. This may be changed in 0.12 D steps.
    • The Alignment Zone is designed to facilitate good centration, which is very important in having positive ortho-k lens outcomes. The aspheric zone aligns with the mid-peripheral cornea to form a wide bearing surface which facilitates the best centration. The zone is fitted in 0.25 D steps
    • The Peripheral Zone affects tear exchange and comfort. This aspheric ‘ski edge lift’ creates controlled edge clearance and ensures optimum patient comfort. Widths range from 0.20 mm to 0.60 mm.
